[cisco-voip] CNAME over QSIG

[malhatma]

Hi,

is it somehow possible to get a CNAME in a facility message, when being called over a QSIG trunk?
Setup:
AvayaGW-QSIG Trunk (ISO)-3825(12.4T)-MGCP-CUCM6.1
Calling name, calling number & called number is working in both directions. But called name is only working from Cisco side. When an Avaya phone calls a Cisco phone the IOS gw doesn't send a 
called name in facility msg (Alerting, Proceeding). I'm not able to find anything helpfull at the Cisco site. Is it not supported? Would be strange. Any suggestions are welcome.

Regards
Andre
