Installing QuadroE1/T1 QuadroE1/T1; (SW Version 2.4.x) 8 Installing QuadroE1/T1 Networking Overview To establish a connection between the PSTN (or your PBX) and the Internet, a VoIP gate- way is needed. The QuadroE1/T1 is a VoIP gateway, and will perform the task of connecting your PSTN (or PBX) via its E1/T1 port to a Private Data Network that includes Quadro SIP routers (Quadro2x, -4x and/or16x) or the Internet. The QuadroE1/T1 will process and regu- late the voice traffic between these networks by means of Call Routing paths that are speci- fied by the administrator according to a dial plan. The QuadroE1/T1 has one additional LAN port that is used to connect a PC for management purposes. The WAN port transmits up to 10 Mbps, and the LAN port transmits at 10 Mbps or 100 Mbps. Fig. I-3: Connection overview Every device within an IP network requires a unique IP address to identify itself. Since the QuadroE1/T1 connects to both the LAN (Admin PC) and the WAN (Private Data Network or Internet), it has to be part of both networks, and must have two IP addresses: one for the WAN side and one for the LAN side. The QuadroE1/T1’s integrated firewall/NAT functional- ity will hide the LAN IP address from the WAN (Internet) side. There are two ways of assigning an IP address: statically or dynamically. The Quadro E1/T1 can be configured with a static IP address on the WAN interface. You also can use a DHCP server assigned IP address on the WAN side. Please Note: A DHCP client is software that requests an IP address from a DHCP server. A DHCP server assigns on request a unique IP address to a device. The QuadroE1/T1 acts as a DHCP client on its WAN interface and as a DHCP server on its LAN interface.

Installing QuadroE1/T1 QuadroE1/T1; (SW Version 2.4.x) 9 Connecting the Hardware Fig. I-4: Connecting the Hardware • Verify the product package contents are complete. Refer to the contents sheet included in the packaging to determine if all the items were shipped in the box. • Connect a telephone to the PHONE port on the QuadroE1/T1’s rear panel. • Connect the QuadroE1/T1’s E1/T1 port to your PBX or the trunk from the PSTN Central Office ONLY after configuring the E1/T1 settings according to the specifi- cations of your PSTN provider. (see Appendix: Pin Assignment of E1/T1) • Connect the Ethernet port on your PC via a straight CAT 5 cable with an RJ-45 connec- tor to the LAN socket of the QuadroE1/T1. If a hub or switch is connected between the QuadroE1/T1 and your PC, use a crossover cable from the LAN interface of the QuadroE1/T1 to the hub/switch. • Connect the WAN port of the QuadroE1/T1 to the Private Data Network or Internet ser- vice. • When using a DSL or Cable modem, power up the modem before the Quadro. • Connect the power adapter to the POWER port on the QuadroE1/T1’s rear panel and plug the power adapter into a power outlet. Only use the original power adapter and plug it into a power strip with surge protection or to a UPS if available. The red LED (Fault) will glow for several seconds followed by the yellow LED (Info), which will glow for several minutes. As soon as Info is off, the QuadroE1/T1 is opera- tional. • Power up any hub or switch followed by any PC and other devices on the LAN side. Please Note: The PC must be configured for DHCP to receive an IP address directly from the QuadroE1/T1. Refer to Appendix: PC DHCP Settings for instructions on how to set up a PC for DHCP operation. • Check the LEDs: The green Busy LED should glow continuously. The green LAN and WAN LEDs will blink when cables are connected to these ports and all devices are pow- ered up. If the green LAN and WAN LEDs do not blink, verify cabling and ensure that all devices are powered up. Please Note: CAT 5 cables can be faulty without visual indication. The LAN and WAN LEDs verify that the Ethernet connection is established between the end points. If these LEDs are not illuminated, there is a connection problem between the QuadroE1/T1 and the other device. Some modems, hubs, switches and routers will require the use of crossover cables.

All these settings must be entered on the man- agement page Trunk Settings that is displayed when you select E1/T1 Settings from the Telephony menu: Fig. I-20: Trunk Settings page The Trunk Settings page is used to configure the E1/T1 trunk and timeslots settings. The table lists the available E1/T1 trunks of Quadro and their settings (Trunk name, E1/T1 mode, interface and signaling type). Clicking on the trunk will open its Signaling Settings page (Trunk CAS Signaling Settings or the Trunk CCS Signaling Settings page depending on the selected signaling type). Selecting the corresponding trunk's checkbox and pressing Edit will open the Trunk - Edit Entry page. The E1/T1 Stats link is displayed for every active Quadro trunk and leads to the page where the E1/T1 trunk and the traffic statistics can be viewed.

Registering on Epygi's Technical Support QuadroE1/T1; (SW Version 2.4.x) 22 Editing the E1/T1 Trunk Fig. I-21: Trunk Edit page Select Network as your Interface Type if your QuadroE1/T1 is connected to a PBX, other- wise choose User. Next, you are required to enter the Signaling type (CAS or CCS), adjust the correct inter- face type (E1 or T1), and specify the requested settings of the selected interface type. The appropriate parameters should be requested from the service provider or in case of connect- ing to a PBX - according to the settings in the PBX manual. CAS signaling allows use of the same timeslot both for voice and data transmission. CCS signaling uses a single timeslot for signaling data transmission for the whole trunk, all other timeslots are used for voice transmission. E1, the European system, enables 30 active timeslots (both for CAS and CCS) to be used; T1, the US system, enables 24 timeslots (if CAS is used) and 23 (if CSS is used). Please Note: Modifying the E1/T1 trunk settings may lead to some broken routes in the Lo- cal Call Routing Table.

Registering on Epygi's Technical Support QuadroE1/T1; (SW Version 2.4.x) 23 Signaling Type CCS Fig. I-22: Trunk T1 Signaling Type CCS page If you selected CCS as your Signaling Type, using the Trunk link will take you to the page shown above. Here you can specify the signaling settings in more detail. Further, this page allows selection of the timeslots for signaling data and voice. The D Channel Timeslot For Transmit/Receive drop down list offers all available timeslots to be selected for signaling data transmit/receive. The Non Automat checkbox switches to non-automatic Terminal Endpoint Identifier (TEI) searching and enables the TEI Address text field that requires a TEI number (digit values from 0 to 63) for connection establishment between CO and E1/T1 client. In automatic mode, an E1/T1 connection will be established on the first available TEI, while in non- automatic mode a specific TEI may be reserved for the connection. In this case both call partners need to specify the same TEI in their settings. In the Network Mode (PBX connected) you need to specify the same TEI address on both sides (Quadro and PBX), if the Non Automat mode is selected. If the Automat mode is se- lected the user on the PBX side may set any mode related to TEI assignment in the PBX configuration. In the User Mode (CO/PSTN connected) the TEI assignment depends on the CO/PSTN set- tings. So you have to enter the values you've got from your PSTN provider. The Excessive Ack. Delay T200 text field configures the period in milliseconds (digit values from 500 to 9999) between transmitted signaling packet and its acknowledgement received. The Idle Timer T203 text field configures the period in milliseconds (digit values from 1000 to 99999) for E1/T1 client idle timeout. The Service Provider provides these settings. Route Incoming call to offers Attendant, Routing, Routing with inbound destination number and 21 (Quadro's FXS extension) to be selected. Routing will request the caller to pass the authentication (if enabled) and will invite the caller to dial the destination number to connect the user within the Quadro Network. Routing with inbound destination number will request the authentication (if enabled) and then will automatically use the initially dialed number to connect the destination without any additional dialing. The value for Switch Type depends on the CO when acting in the User mode and the pri- vate PBX capabilities when acting in the Network mode. The link B Channels leads to the Signaling Type CCS - B Channel Settings page (see below) where available timeslots may be enabled/disabled for the voice transfer. The Force Update option can be optionally used to apply new settings immediately. This will force the

Registering on Epygi's Technical Support QuadroE1/T1; (SW Version 2.4.x) 24 timeslot(s) to be restarted and any active connection on the selected timeslot(s) will be inter- rupted. Edit will display another page, where the signaling settings for the selected timeslots may be specified in detail. Attention: A timeslot can be used either for voice or signaling data transfer. The configura- tion prevents the selection of a timeslot from the B channel list if it has already been selected from the D Channel receive/transmit drop down list. Fig. I-23: Trunk T1 Signaling Type CCS - B-Channels page Edit will display another page (see below) where the signaling settings for the selected time- slots may be enabled or disabled and the Force Update Timeslot service may be enabled to apply new settings immediately. This will force the timeslot(s) to be restarted and any ac- tive connection on the selected timeslot(s) will be interrupted. Fig. I-24: Trunk T1 Signaling Type CCS - B-Channels Edit page

The page lists all timeslots and allows editing of the signaling settings for each single timeslot: Fig. I-26: Trunk T1 Signaling Type CAS page

Registering on Epygi's Technical Support QuadroE1/T1; (SW Version 2.4.x) 26 Here you may Enable the timeslot by checkbox and select whether the DID Service (Direct Inward Dialing) shall be disabled or enabled. In User mode, the Quadro cannot route incoming calls from the E1/T1 trunk to extensions if the timeslot in the trunk does not have DID service enabled. Incoming call routing takes place according to the received caller ID. If the DID service is enabled on some timeslot(s), an incoming call on these timeslots may be routed to the specified extension, the Attendant, or the routing client (depending on the configuration). Please Note: The timeslot with DID service enabled cannot be used for outgoing calls. In Network mode DID service does not limit the Quadro functionality but a timeslot with en- abled DID service cannot be used for incoming calls. Please Note: The CO/private PBX must support the DID service, if it is to be configured on the QuadroE1/T1.

Registering on Epygi's Technical Support QuadroE1/T1; (SW Version 2.4.x) 27 Setting up Call Routing The Call Routing service allows you to specify the communication structure between all in- volved devices by developing a dialing plan and setting the call routing paths accordingly. For the Quadro extension users, the call procedure should be simple and familiar for all kinds of calls (internal, IP, PSTN or IP-PSTN). The possibilities Call Routing offers are numerous. The following configuration just a single example used to explain setup of the QuadroE1/T1 as a gateway: In this example, the QuadroE1/T1 is connected within a protected Private Data Network built of two other Quadro devices (-2x and -4x) where 6 extensions are connected. Each exten- sion will be configured such that they all shall reach each other and the PSTN. The exten- sions also shall be reached by calls from the PSTN. Fig. I-27: Call Routing example Your PSTN Service Provider supplies you with a set of PSTN telephone numbers for your E1/T1 line. If you want to assign these numbers to the phones connected to the Quadro2x and Quadro4x within your Private Data Network, you have to create a dial plan to define Call Routing paths on the QuadroE1/T1 and on each of the other Quadro devices. To illustrate the dial plan with an example, we will assume, you have the phone number set 854603-30 to 854603-59 and you assigned the numbers as follows: Quadro 2x (IP: 10.20.30.10) Quadro4x (IP: 10.20.30.20) QuadroE1/T1 (IP: 10.20.30.30) Auto Attendant 854603-30 Auto Attendant 854603-40 Extension 1 854603-50 Extension 1 854603-31 Extension 1 854603-41 Extension 2 854603-32 Extension 2 854603-42 Extension 3 854603-43 Extension 4 854603-44 Auto Attendant: All numbers of the numbers set, that are not assigned to an ex- tension are caught here

Registering on Epygi's Technical Support QuadroE1/T1; (SW Version 2.4.x) 28 All unassigned numbers of the phone number set will lead to the Auto Attendant of QuadroE1/T where a message may inform the callers that the dialed number does not exist. Fig. I-28: Call Routing example; dialing plan To define the call routing paths needed on QuadroE1/T1 open Call Routing in the Teleph- ony menu and select Local Routing Table. The Call Routing - Local Routing page will be displayed (it is a wide table, thus it is shown here and in the following pictures in two parts): Fig. I-29: Call Routing - Local Routing page

Registering on Epygi's Technical Support QuadroE1/T1; (SW Version 2.4.x) 29 Before you can start defining the local call routing paths, you have to select Add to define the first call routing path that leads the incoming PSTN calls 854603-30, -31 and -32 to the Quadro2x. Fig. I-30: Routing Call Type Add Entry page Pattern requires the routing pattern. To make the specified call, the appropriate Call Code should be dialed prior to the routing pattern. Only digit values and wildcard symbols are al- lowed here: • the "?" character stands for only one unknown digit • the "*" character stands for any number of any digits. • '[' , ']' , ',' and '-' are used to define a range or a quantity of numbers, e.g. 8546033[0-2] means that the dialed number may be 8546033-0. -1 or -2 to match the specified pat- tern; for 2[3,7], the dialed number may be 23 or 27 to match the specified pattern. Number of Discarded Digits (NDD) specifies the number of digits that that should be dis- carded from the beginning of the routing pattern. In this example, no digits have to be dis- carded, so leave that field empty. Prefix specifies digits that will be inserted at the beginning of the routing pattern. Leave the field empty if no digits need to be added. Call Type gives a possibility to select the routing call type (PBX, IP, IP-PSTN or E1/T1). For this example IP has to be selected. Metric allows entry of a rating for the selected route in a range from 0 to 20. If no value is in- serted into this field, 10 will be used as a default. When two route entries match a user's dial string, the route with the lower metric will be preferred. In this example the Metric field will be left empty. Description allows entry of short text, e.g. to name the path. Fill Call Source Information allows to limit the functionality of the current route to be used by the defined caller(s) only. If this checkbox is enabled, inbound caller information (Inbound Caller Pattern, Inbound Call Type, Inbound Port ID, etc.) will be required further in the Local

Registering on Epygi's Technical Support QuadroE1/T1; (SW Version 2.4.x) 30 Call Routing Wizard (see Manual-II, Administrator's Guide). In this example, no caller spe- cific limitation is needed, so leave that checkbox unchecked empty. Please Note: This checkbox selection, as well as any Inbound Caller information inserted, won’t be considered and will make the current routing pattern invalid, if the E1/T1 Settings are switched to CAS mode, Loop Start, Group Start, E&M, R2 DTMF or R2 Compelled/Non Compelled (without ANI) signaling types. Next will display the second page of the Local Routing Wizard Fig. I-31: Routing Call Settings - Add Entry page Enter the IP address of the Quadro2x into the Destination IP Address text field. Destination Port requires the port number of the destination or the SIP server. As Quadro devices use port 5060 per default, enter 5060. User Name and Password are identification settings for public SIP servers or servers re- quiring authentication. Leave these fields empty. Call End Point defines whether the destination is the end point (specified user will ring) or if the remote destination Routing Table should be parsed for matching patterns to continue call routing. As the destination is the endpoint in this example, check this checkbox Fail Reason offers a list of fail reasons depending on the selected call type. If the selected fail reason occurs, the local routing table will be parsed for the next matching pattern, and if found, the call will be routed to the destination specified there. In the example described here, the default value None is used. The third page of the Local Call Routing Wizard summarizes all settings and Finish will save the route. The Call Routing - local Routing page is displayed again showing the new call routing path:

Appendix: PC DHCP Settings QuadroE1/T1; (SW Version 2.4.x) 33 Appendix: PC DHCP Settings The QuadroE1/T1 LAN port has a DHCP server that provides DHCP IP addresses to de- vices connected to the LAN either directly or through an Ethernet hub or switch. Appendix A describes how to configure Windows PCs for DHCP. The PC used to access the QuadroE1/T1 must meet the following conditions: • TCP/IP network protocol has to be installed. • DHCP has to be activated to request the IP address automatically. Please Note: If your PC is already configured for DHCP, then simply power it on. Verify the LAN LED is lit. If not, check the cable connections. Follow the instructions below to install TCP/IP and enable DHCP functionality: TCP/IP and DHCP under Windows 2000/Windows XP Windows 2000 and Windows XP PCs with Ethernet cards or adapters normally are config- ured with a TCP/IP network connection by default.

Appendix: Configuring SIP NAT Traversal QuadroE1/T1; (SW Version 2.4.x) 36 Appendix: Configuring SIP NAT Traversal The QuadroE1/T1 initiates and receives SIP calls from the network connected to the WAN port) To receive SIP calls, the QuadroE1/T1 must be able to receive packets from the SIP server or any other device that is trying to make an incoming call. If the QuadroE1/T1 is placed behind a router with NAT, like most basic routers on the market today, the QuadroE1/T1 will not be able to receive calls. To resolve this issue, either STUN must be enabled on the QuadroE1/T1 or SIP NAT traversal must be set up in the router and in the QuadroE1/T1 to properly route the incoming calls. NAT or Network Address Translation is a common feature used to expand the use of con- nected PCs and other networked devices without having to use multiple global Internet pub- lic IP address. Most ISP will assign one public IP address to each customer that is con- nected to the Internet. The customer can use a router to provide NAT capability and create a private network of PCs and other devices not visible to the Internet. This method offers security and also eliminates the need to assign global Internet public IP addresses to each device. Please Note: SIP NAT traversal only works with Internet connections that have static IP ad- dresses. Verify from your provider this is the case for your Internet connection. Some ISPs provide dynamic IP addresses that may change from time to time, and are not appropriate for SIP NAT traversal. Please Note: If you have more than one router in series between the QuadroE1/T1 and the Internet, the same port forwarding setup must be configured on each router. SIP NAT Traversal Setup • Install the QuadroE1/T1 behind the router. If the QuadroE1/T1 is configured with its fac- tory default settings, it is already configured for DHCP and will obtain an IP address automatically from the router. If the DHCP was changed, please run the Basic Configuration Wizard to place the QuadroE1/T1 in DHCP mode. Power up the QuadroE1/T1. • Connect a PC or laptop to the QuadroE1/T1 LAN port and power it up. • Verify the QuadroE1/T1 can connect to the Internet by opening a browser window and browsing to a familiar WEB site. If the QuadroE1/T1 can not reach the Internet, verify the LAN/WAN LEDs and the cabling. Verify the QuadroE1/T1 is set up for DHCP on the WAN and that the router has the DHCP server enabled for the devices behind it. • Find the address of the router and log into the router. Refer to the router user manual on how to open the router configuration. • Set up port forwarding on the router to forward the UDP ports according to the ports specified for SIP (Mapped Port for SIP, default: 5060) and RTP/RTCP (Min mapped RTP/RTCP port (default 6000 and Max mapped RTP/RTCP port (default 6099)) on the QuadroE1/T1. The router should forward that UDP (USP/TCP for SIP) ports to the IP address assigned to the QuadroE1/T1. You can see the IP address of the QuadroE1/T1 in the System menu under Status. The IP address will be listed as the WAN IP address. Your router may also indicate the IP address assigned to the QuadroE1/T1. • Find out the public Internet address of the router. To do so, open a browser and go to www.whatismyip.com. The site will return your public Internet IP address. Record this IP address. • From the QuadroE1/T1 Management menu go to the SIP Settings menu and check Use Manual NAT Traversal for SIP. For NAT station IP, enter the public Internet IP address found on the step above and the port numbers for SIP and RTP/RTCP. The de- fault values are: • For Mapped Port for SIP 5060 • For Min mapped RTP/RTCP port 6000 • For Max mapped RTP/RTCP port 6059 • Click the Save button to save the contents.

Appendix: Configuring SIP NAT Traversal QuadroE1/T1; (SW Version 2.4.x) 37 The QuadroE1/T1 will activate the settings and register the extension on the Epygi SIP Server after a few minutes. You can verify the settings from the main QuadroE1/T1 Management menu under Status in the SIP Registration Status section.

Appendix: Checking the Connections QuadroE1/T1; (SW Version 2.4.x) 38 Appendix: Checking the Connections If the system seems to work incorrectly even when all cables are connected properly, it may be helpful to Start Network Diagnostics: The WAN link, IP configuration, gateway, DNS server, and STUN-NAT (if used) will all be checked. To start diagnostics, open the System's menu item Diagnostics and click Start Network Diagnostics. Fig. I-35: System Diagnostics page In the case of a successful test, the output of the system looks as follows: Basic Tests: Checking for physical link: WAN link ok Checking IP configuration: dynamically via DHCP Client DHCP Client is running Checking internet connectivity (ICMP ping): Gateway: reached Primary nameserver: reached Secondary nameserver: not configured www.epygi.com: reached STUN Network Address Translation (NAT) Check: External visibible address: 212.126.210.179 Detected NAT type : Restricted cone Performing MTU Discovery: preparing system Sending UDP Datagram of size 1500 got answer clean up Largest usable MTU size is: 1500 Bytes Test successful.

Appendix: Checking the Connections QuadroE1/T1; (SW Version 2.4.x) 39 Depending on where the test is failing, the diagnostic can give some advise to solve the problem. See the example below of a failed test: Basic Tests: Checking for physical link: no WAN link Please check the physical connection of the WAN interface. Cable not plugged or broken? Test failed. If you pass the diagnostics successfully, but are still not able to place a call to 899# then check the SIP registration status. Open the SIP Registration Status page using the QuadroE1/T1 management System menu item Status. If QuadroE1/T1 is placed behind a NAT router, the detected NAT type and the IP address of this router's WAN port is displayed. Fig. I-36: SIP Registration Status page If you are using the STUN functionality the page shown above will additionally display the Detected Connection Type. Unsupported Connection types will cause one of the following messages: • Unknown connection - unexpected error, • Symmetric NAT, • Symmetric Firewall, • Blocked UDP If the Detected Connection Type is any of the types listed above, QuadroE1/T1 cannot work behind your router. You must either connect the QuadroE1/T1 in front of the router, or configure NAT traversal manually as explained in Appendix: Configuring SIP NAT Tra- versal If you are unable to resolve your problems, please send us a technical support request on the Support section of http://www.epygi.com/. Please prepare a system log file and attach it to your request. To create a system log file, open the System Diagnostics page System menu item Diagnostics) and click Download System Logs.
