MGCP with CCM3.0 and CCM3.1

[admin_2]

We have CCM 3.0 and CCM 3.1. We tried to match the configuration on both CCMs.

The FXS client (VG200 running MGCP) box has two FXS ports and attach two phones. If registered with CCM3.0, both phones can call simultaneously.

But when we try to use CCM3.1, only one of FXS can make the call. Is there any difference between the CCM? Or where the setting in CCM should I check?

This don't sound right and I think we should follow

these steps towards a resolution.

1. Check if you have not mistakenly setup a location and put the bandwidht available for the called

location at a low value, which could be another reason for the

failed second call

2. Check to see if the right calling search space is configured on the second phone. send a debug mgcp

packets on the c2600 showing this defect.
