Auth Resync-Reboot
SIP Proxy-Require
SIP Remote-Party-ID
SIP GUID
If this feature is enabled, the SPA9000 authenticates the
sender when it receives the NOTIFY resync reboot (RFC
2617) message. To use this feature, select yes. Otherwise,
select no.
Default: yes
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.
Default: blank
To use the Remote-Party-ID header instead of the From
header, select yes. Otherwise, select no.
Default: yes
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
