Configuring SIP Server
The MultiVOIP 210/410/810-SS models have the additional capability of SIP survivability. This section describes
the settings for SIP server mode.

In “Survivability” mode, the MVP-SS unit can function as a SIP server for
other gateways in its network in case that network loses contact with the
network’s main SIP server (typically a PBX). When in “Survivability” mode the
unit is a backup SIP server.
In “Stand-Alone” mode, the MVP-SS functions as a primary SIP server for
other gateways. In this mode, the MVP-SS operate to technical advantage
with ‘smart’ SIP phones. Such smart SIP phones can choose the SIP server
under which they operate and, consequently, can be controlled by either the
SIP-based PBX or by the MVP-SS
Survivability
Status Check
Register,
Options
One of two status-check packets is sent to the main SIP Proxy servers to
which the MVP-SS serves as a backup. This packet determines if the MVP-SS
takes over SIP server functions or stays in normal backup mode. “Options”
and “Register” are two SIP request “methods.” The Options method solicits
information but does not set up a connection. The Register method conveys
information about a user’s location to the SIP server. The “Register” method
may entail more data overhead than the “Options” method. If your SIP
server supports these methods, you can use either one. If only one is
supported, use the supported method.
Registrar Options
Allow Undefined
Registrations
Y/N
If undefined registrations are allowed, then gateways other than those listed
in the Predefined Endpoints list can register with the MVP-SS unit as it
functions in its SIP server mode. If undefined registrations are not allowed,
then incoming registrations are allowed if they originate from endpoints at
accepted domains or IP addresses.

Defines if registrations to the MVP-SS SIP server are accepted from any
domain or only from specified domains. Multiple domains can be listed,
separated by semicolons. The “any domains” option is intended for private
networks not accessible through Internet.
