[cisco-voip] QSIG: Display name decoding fails

[Dietmar]

Hi all,

I have an ISO-QSIG connection between a MGCP controlled 2821 (backhauled to 
CCM 4.1(3)) and a Tenovis PBX.

When someone places a call from the Tenovis towards the 2821, Callmanager 
seems to be unable to decode the display name (CNAM) of the calling party. 
However, the trace below shows that it is included within the facility.

Can anyone tell me what is going wrong there?

Thanks, Dietmar
