Interoperability With Cma - Polycom RMX 1500 Administrator's Manual

Chapter 17-Gateway Calls
17-12
For example:
• The ISDN prefix is 9251.
• The dial in number range defined in the ISDN Network Service can
be 100 to 400 (that is, 9251100 to 9251400).
• The dial in numbers assigned to the Gateway Profile can the entire
range, or part of the range of other Gateway Profiles are to be used:
100 to 200. (that is 9251100 to 9251200)
• The aliases assigned to the IP endpoints will range between 100 to 200
or 400 (for the full range) as well.
• MCU Prefix in the gatekeeper: 79.
• Number of digits to append (same as the ISDN prefix is this
example): 3
• The destination endpoint alias is 123.
• The ISDN endpoint dials 9251123. The RMX truncates the four first
digits 9251 replacing them with 79 and appends 123 to 79, to create
the destination number 79123 which is sent to the gatekeeper for
routing.

Interoperability with CMA

The RMX does not register to the gatekeeper as a Gateway, therefore it is
recommended to create and use the CMA Dialing Rules to enable the CMA
Dial One Method.
When the caller enters the Dial One digit as the destination number prefix,
the CMA replaces this digit with the MCU prefix in the Gatekeeper and
the ID of the Gateway Profile. For example, the calling participant can
enter 99251444, where 9 is the digit that is used as the MCU prefix
registered in gatekeeper and is replaced by the gatekeeper with * and the
Gateway Profile ID (for example, *2000) as defined in the Dialing Rule.
For more details on Dialing Rules definition in the CMA, see the Polycom
CMA System Operations Guide, "Dial Rule Operations".
