ISDN Gateway Selection Process

When the dial string begins with a simplified ISDN gateway dialing prefix, the Polycom RealPresence DMA system chooses an ISDN gateway by applying the following steps:

1Strip the ISDN gateway dialing prefix from the dial string, leaving the E.164 number.

2From 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 RealPresence Collaboration Server or RMX MCUs). If none, go to 3; otherwise, go to 4.

3From the remaining gateways, select those with a profile bit rate lower than the requested bit rate. If none, reject the call.

4From the remaining gateways, select those that match the country code and area code of the dialed number. If none, go to 5; otherwise, go to 6.

5From the remaining gateways, select those that match the country code of the dialed number, if any.

6From the remaining gateways, select those with a profile that has the closest bit rate. An exact match is preferred.

7From the remaining gateways, select those that are in the same site as the calling endpoint, if any.

8From the remaining gateways, select one using a round-robin method.

9If the call fails because of no capacity on the selected gateway, select the next gateway left in 8. If none, start again at 2 (omitting the gateway that failed). If none left, reject the call.

10If a gateway is successfully selected, assemble a dial string to send to the gateway as follows:

<direct dial-in prefix><session profile prefix><delimiter><E.164 number>
