Hello to everyone,
We have a gw MGCP and another H.323, CCM version 5.1.3. In order to save costs we want reduce the number of channels of our E1 PRIs (currently 30) to 10 or 20 depending of the number of calls per gateway. Our telco is preparing this request.
I think that there is not any problem to reduce the channels in pri-group time slots configuration related to incoming calls but for outgoing calls I´m not pretty sure.
There is any document with restrictions or issues related to this matter with MGCP or H323?
Thank you very much for your help.
As far as I know the following is still true:
Cisco CallManager does not support the configuration or use of a fractional PRI when you use it with MGCP. If fractional PRI is necessary, you can use H.323 instead of MGCP.
