Chapter 21 Voice Table 114 VoIP > SIP > SIP Service Provider > Add new provider/Edit (continued) LABEL SIP Server Address SIP Server Port REGISTER Server Address REGISTER Server Port SIP Service Domain RFC Support Support Locating SIP Server (RFC3263) DESCRIPTION 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. Enter the SIP server's listening port number, if your VoIP service provider gave you one. Otherwise, keep the default value. 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. 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. 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. Select this option to have the Device use DNS procedures to resolve the SIP domain and find the SIP server's IP address, port number and supported transport protocol(s). The Device first uses DNS Name Authority Pointer (NAPTR) records to determine the transport protocols supported by the SIP server. It then performs DNS Service (SRV) query to determine the port number for the protocol. The Device resolves the SIP server's IP address by a standard DNS address record lookup. RFC 3262(Require: 100rel) The SIP Server Port and REGISTER Server Port fields in the General section above are grayed out and not applicable and the Transport Type can also be set to AUTO if you select this option. 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 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.
