receives the NOTIFY resync reboot (RFC 2617) message. To use this
feature, select yes. Otherwise, select no.
Default:
yes
SIP Proxy-Require
The SIP proxy can support a specific extension or behavior when it
detects 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

SIP GUID
The Global Unique ID is generated for each line for each device. When it
is enabled, the SPA9000 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.
Default:
no
