ISDN Gateway Selection Process
The Polycom DMA system chooses an ISDN gateway for simplified gateway
dialing by applying the following steps:
1 From the in-service (not busied out or out of service) gateways, select the
ones that have a profile with a matching or higher bit rate (higher bit rate
can only be used for RMX). If none, go to 2; otherwise, go to 3.
2 From the remaining gateways, select those with a profile bit rate lower
than the requested bit rate. If none, reject the call.
3 From the remaining gateways, select those that match the country code
and area code of the dialed number. If none, go to 4; otherwise, go to 5.
4 From the remaining gateways, select those that match the country code of
the dialed number, if any.
5 From the remaining gateways, select those with a profile that has the
closest bit rate. An exact match is preferred.
6 From the remaining gateways, select those that are in the same site as the
calling endpoint, if any.
7 From the remaining gateways, select one, using a round-robin selection
method.
