Hi,
A have configured a E1 PRI ISDN to connect to the PSTN, I can make outgoing calls, but the incoming calls are not working. I performed the following command to get traces edt trace tsp l2l3 3 1 2 1 and the traces shows the following error, -0101100 Cause code: requested cct/chan unavail.
Below you have the complete trace output. Our PSTN provider sends the last 3 digits of the DID (000 to 099), In the PBX we have the extensions 4000 to 4099, so I have configured the Trunk Service Assignments to do not absorb any digit and to add the digit 4 to the incoming number.
