SIP Server: Predefined Endpoint Parameters.
In this screen you will specify the VOIP gateways that will depend on the MVP-SS unit either as their
primary SIP server (if the MVP-SS is used in “Stand-Alone” mode, as set in the
SIP Server | Configuration
screen) or as their backup SIP server (if the MVP-SS is used in “Survivability” mode, as set in the
SIP
Server |Configuration screen).
The main screen for Predefined Endpoints is a list. If you click on function buttons to
Add or Edit entries
in this list of endpoints, a secondary screen will appear and allow you to add new endpoints or edit
existing endpoint entries. When your work with the list is complete, click
Save.

Password

This password is for authentication of gateway to SIP server.
Registration Type Static,
Dynamic
Static registrations are fixed and the contact information for them is configured
by the user and not subject to removal from the registration list due to timeouts.
Dynamic registrations are registered from an external endpoint with the contact
information. Dynamic entries must re-register before the re-registration interval
expires else they will be removed from the list. Endpoints removed from this list
can neither make nor receive calls.
Re-Registration
Interval
integer
values; in
seconds;
default is
3600
The time after which the MultiVOIP UserAgent Client is supposed to register with
the proxy server.
Expiration of the registration interval means that the gateway has lost contact
with the main SIP server and that the MVP-SS unit will enter its ‘survivability’
mode. In survivability mode, the MVP-SS unit will complete calls acting as a
backup to the main SIP server. Normally, however, the MVP-SS will initiate re-
registration with some small margin of time before the interval lapses.
