Hi Mangi,

ISDN CCBS is for PUBLIC ETSI trunks that support callback. For private trunks between PBX's you need to ensure you have at least one NCA-TSC configured. What does MST tell you?

Hi Mangi,

The Avaya is sending the Callback Request (CCBS) to the Alcatel who replies with: with:

4001180f ==> REL_COM crv 1_7da3 bad ie content !
D-channel port number: 4001180f
Protocol Discriminator: 08 call control
Call Reference Value: 02 fd a3 Destination 7da3

You will have to ask them what they don't like.
