SIP Settings
Field Description
SIP Port Port number of the SIP message listening and transmission port.
The default is 5060.
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 SPA9000 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
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.
The default is yes.
