[cisco-voip] CUCM/HiPath QSIG Integration - Callback CCNR/CCBS not working -

[Bob Zanett (US)]

One way, if your gateway is H323/SIP, you can use translation profiles to modify every call outbound on the QSIG trunk(s).

Hi List,

i have the following Problem: Callmanager is connected to a Siemens HiPath via an E1 QSIG Connection. For this connection we have to use Number Plan ISDN and Number Type International for the calling number and the called number. Basic Calls are working fine.

Callback (CCNR/CCBS) is  working only in one Direction, HiPath to CUCM. From CUCM to HiPath Callback is not working, as far as we use ISDN/International for calling/called number. If we change to unknown/unknown for calling/called number, Callback is working from CUCM to HiPath. The HiPath engineer assumes that the NumberPlan/NumberType ISDN/International is causing the issue. Because, we found out that the calling/called number inside the Callback request are still unknown/unknown though the calling/called numbers from the original call are ISDN/International.

Does anybody know if it is possible to change the NumberType/NumberPlan, inside the callback Request to ISDN/International? Or, does anybody know how to configure the HiPath System to accept unknown/unknown even if the original called/calling numbers are in ISDN/International Format?

The Callmanager we are using is 7.1.3.32900-4, 7.1.3SU2b I think. The version of the HiPath, I do not know.

Many thanks in advance,

/Robert
