Packets are routed to the PBX based on the set port routing IP address on the router. STUN – fill in the STUN server address and port to identify the current address behind the NAT router. Authorisation required – activate authorisation request for incoming calls from the counterparty. User login data are used for call authorisation. All logins are always searched through. Remote SIP Server Parameters Connect to – set the IP address or DNS name of the counterparty (operator or another PBX) to which you want to connect the via a 2N IP Audio Manager ® trunk (where call and registration requests shall be routed). To use a port other than 5060, specify the port behind the colon (192.168.122.43:5071). Protocol – specify whether UDP and/or TCP shall be used for transmission. If you choose NAPTR (Name Authority PoinTeR), a query to the DNS is made first and, depending on the reply, the proper transmission protocol is set. The Use DNS SRV parameter can be used with this setting and suitable DNS only. Register line – enable registration with the counterparty and specify the gateway registration number (Caller ID). No call setup requests can be resent to an unregistered gateway. Validity – set the registration validity term. The resultant value can be defined by the counterparty (if shorter). Authorisation Data Name – user name for registration with the counterparty. Password – password for registration with the counterparty. Trustful IP Addresses The parameter helps secure the against undesired call 2N IP Audio Manager ® attempts via the given SIP gateway. Tick off this option to make the PBX process only the requests coming from trustworthy IP addresses included in the list. Add, remove or modify an IP address to/in the list using the buttons to the right of the IP address list or the context menu retrieved in the IP address list with the right–hand mouse button.

® SIP Parameters Figure: Advanced VoIP Settings Always mediate RTP – enable this parameter to route the RTP stream via the PBX VoIP card in all cases. Otherwise, the RTP stream might be routed outside the PBX (for VoIP – VoIP connections) and the PBX processes only signalling for such a call. Reverse RTP negotiation – tick off this option to set the codec negotiating method. If you do not tick off this option, the PBX offers codecs in the INVITE message. Use short headers – tick off this option to use abbreviated header items for outgoing SIP packets. Example: From = f, To = t, Via = v. This optimisation helps minimise data to be transmitted. Do not replace +,#,* in numbers – if you do not tick off this option, the above mentioned characters will be replaced with adequate strings %xx in numbers. Tick off the option to send the characters. Route by To header – if you tick off the option, incoming call routing on the port will obey the To header setting. Otherwise (and by default!), calls are routed by the Request URI header. Dedicated Registrar – is used for the gateway only and helps route registration to another server. Address – IP address of the selected Registrar server. Port – port of the selected Registrar server. Scheme – set the or scheme in the "To" and "From" headers of the SIP. sip tel tel is used for networks based on the numbering plan according to recommendation E.164. Min. MTU – set the minimum packet length for obligatory use of TCP in the

® UDP&TCP mode. The recommended maximum value is 1448 bytes. Headers Complete domain – specify the domain to be used within the From and To headers. Send information – – activate the P–Asserted–Identity P–Asserted–Identity header for the INVITE message. This header is used for CLIR transmission to the counterparty, giving it information on the calling number even in the case of active CLIR (Calling Line Identification Restriction). By default, the header is enabled on the SIP Gateway and disabled on the SIP Proxy. Aliases Use this option to specify additional Realms (Domains) to be accepted on this port. Such incoming calls (their INVITEs) will be routed to this port whose Request–URIs match the given SIP GW or SIP Proxy settings and Domains or Aliases. RTP DSP– here you can optimise data to be transmitted. Packets are not sent while the user is not speaking. VAD stands for Voice Activity Detection. Disabled VAD VAD acc. to G.729 Annex B VAD light Generate comfort noise – enable comfort noise generating. As users of classic analogue lines are used to some background noise, this option simulates a similar call impression to them. Mask lost packets – enable optimised computing of probable contents of lost packets. QoS The section helps you set outgoing packet parameters which define the TOS/DiffServ packet priority for processing by network elements. SIP – hexadecimal priority value for SIP packets. RTP – hexadecimal priority value for RTP packets. Default values – restore the default values for the two parameters. Echo Suppression Use this tab to activate various echo cancelling methods. Suppression disabled Profile G.168 8 ms Profile G.168 16 ms Profile G.168 32 ms Profile G.168 64 ms Profile G.168 128 ms Delay [ms] Adaptive suppression Non–linear processing Reuse of coefficients Automatic control

Send marks by INFO method DTMF – select one of the two DTMF sending modes using the SIP INFO method. The modes have different formats of the DTMF transmitting message. KeepAlive Period – define the KeepAlive packet sending interval. The default value is 10s. STUN server The STUN server helps NAT clients (i.e. PCs behind the firewall) set up telephone calls with the VoIP provider hosted outside the LAN. – complete the STUN server address (IP or domain name) to be Address used if the STUN IP method is selected in the port RTP interface configuration. The default value is . stunserver.org – set the port to be used for STUN. The default value is . Port port 3478

® Scheduler Scheduler Scheduler is used for creating actions used for control of playlists or sessions. You can schedule various actions for the playlists and assign them to time. A set of actions for playlists is called and you can control multiple playlists in multiple sessions Event within one event. Fig.1 shows an example of event with two sessions. One contains a playlist, the other is without a playlist. Event Creation As mentioned above, the event is a set of actions that are executed over playlists or other sources included in sessions.
