Chapter 21 Voice Each field is described in the following table. Table 96 VoIP > SIP > SIP Service Provider > Add new provider/Edit LABEL DESCRIPTION SIP Service Provider Selection Service Provider Select the SIP service provider profile you want to use for the SIP account you configure in this Selection screen. If you change this field, the screen automatically refreshes. General SIP Service Provider Select this to enable the SIP service provider. SIP Service Enter the name of your SIP service provider. Provider Name SIP Local Port Enter the VMG's listening port number, if your VoIP service provider gave you one. Otherwise, keep the default value. SIP Proxy Server Address Enter the IP address or domain name of the SIP server provided by your VoIP service provider. You can use up to 95 printable ASCII characters. It does not matter whether the SIP server is a proxy, redirect or register server. SIP Proxy Server Enter the SIP server's listening port number, if your VoIP service provider gave you one. Port Otherwise, keep the default value. SIP REGISTRAR Server Address Enter the IP address or domain name of the SIP register server, if your VoIP service provider gave you one. Otherwise, enter the same address you entered in the SIP Server Address field. You can use up to 95 printable ASCII characters. SIP REGISTRAR Server Port Enter the SIP register server's listening port number, if your VoIP service provider gave you one. Otherwise, enter the same port number you entered in the SIP Server Port field. SIP Service Domain Enter the SIP service domain name. In the full SIP URI, this is the part after the @ symbol. You can use up to 127 printable ASCII Extended set characters. RFC Support PRACK (RFC 3262, Require: 100rel) PRACK (RFC 3262) defines a mechanism to provide reliable transmission of SIP provisional response messages, which convey information on the processing progress of the request. This uses the option tag 100rel and the Provisional Response ACKnowledgement (PRACK) method. Select this to have the peer device require the option tag 100rel to send provisional responses reliably. VoIP IOP Flags Select the VoIP inter-operability settings you want to activate. Replace dial digit '#' to '%23' in SIP messages Replace a dial digit "#" with "%23" in the INVITE messages. Remove the 'Route' header in SIP messages Remove the 'Route' header in SIP packets. Bound Interface Name Bound Interface If you select LAN or Any_WAN, the VMG automatically activates the VoIP service when any LAN Name or WAN connection is up. Outbound Proxy Outbound Proxy Address Outbound Proxy Port If you select Multi_WAN, you also need to select two or more pre-configured WAN interfaces. The VoIP service is activated only when one of the selected WAN connections is up. Enter the IP address or domain name of the SIP outbound proxy server if your VoIP service provider has a SIP outbound server to handle voice calls. This allows the VMG to work with any type of NAT router and eliminates the need for STUN or a SIP ALG. Turn off any SIP ALG on a NAT router in front of the VMG to keep it from re-translating the IP address (since this is already handled by the outbound proxy server). Enter the SIP outbound proxy server's listening port, if your VoIP service provider gave you one. Otherwise, keep the default value. VMG4927-B50A / VMG9827-B50A User's Guide 219
