we are trying to connect a CUCM (Ver. 7.1(3b)SU2) with MGCP over a E1 trunk to a Hipath 4000. We use for the QSIG ECMA with Globale Values.
Features like callback and call forward by reroute works fine, but we don't get the caller name on the Cisco Phone (6961 and 7975) from the HiPath Phones.
Have I maybe this issue with the 7.1.(3b)SU2 version, or should I downgrad to 7.1(3a)SU1 aka (18.104.22.16800-4)?
We still let configured at the HiPath the ?Segment? 8?
Thanks for your suggestions in advance.
