DESCRIPTION
Enter a descriptive name of up to 63 printable characters for this SIP
service provider profile. Spaces are not allowed.
Enter the VDSL Router'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 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 VDSL Router use DNS procedures to
resolve the SIP domain and find the SIP server's IP address, port
number and supported transport protocol(s).
The VDSL Router 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 VDSL Router resolves the SIP server's IP
address by a standard DNS address record lookup.
The SIP Server Port and REGISTER Server Port fields are grayed
out and not applicable and the Transport Type can also be set to
AUTO if you select this option.
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 VDSL Router include a SIP Require/Supported
header field with the option tag 100rel in all INVITE
the VDSL Router receives a SIP response message indicating that the
phone it called is ringing, the VDSL Router sends a PRACK message to
have both sides confirm the message is received.
If you select this option, the peer device should also support the option
tag 100rel to send provisional responses reliably.
Use this section to modify the header or some information in SIP
messages in order to resolve interoperability issues with some SIP
servers.
