SIP 100REL Enable To enable the support of 100REL SIP extension
for reliable transmission of provisional responses
(18x) and use of PRACK requests, select yes.
Otherwise, select no.
The default is no.
EXT SIP Port The external SIP port number.
Auth Resync-Reboot If this feature is enabled, the SRP authenticates
the sender when it receives the NOTIFY resync
reboot (RFC 2617) message. To use this feature,
select yes. Otherwise, select no.
The default is yes.
SIP Proxy-Require The SIP proxy can support a specific extension
or behavior when it sees this header from the
user agent. If this field is configured and the
proxy does not support it, it responds with the
message, unsupported. Enter the appropriate
header in the field provided.
SIP Remote-Party-ID To use the Remote-Party-ID header instead of the
From header, select yes. Otherwise, select no.
The default is yes.
SIP GUID The Global Unique ID is generated for each line
for each device. When it is enabled, the SRP
adds a GUID header in the SIP request. The GUID
is generated the first time the unit boots up and
stays with the unit through rebooting and even
factory reset. This feature was requested by Bell
Canada (Nortel) to limit the registration of SIP
accounts.
The default is no.
