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 GUID The Global Unique ID is generated for each line for each
device. When it is enabled, the ATA device adds a GUID

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.
Default setting: no
