CUCM 9.1 CALL Forward shows Extension without Prefix

Hi ,


I have a site with CUCM 9.1 and using MGCP GW.


I have an extension 5234 with a prefix applied for Calling Party for the  outgoing calls like prefix 03112.


The Calling Party Selection is set as " First Redirect Number".

"call forward all" is set to an external mobile number on the extension 5234.


When someone calls on the extension 5234 and call is being forwarded, I see only the extension number(5234) as calling party in the MGCP GW while doing the ISDN q931. Can any please suggest why this is happening?


But when a call is made from the extension 5234, the calling party number is displayed as 031125234.

Hi Faizal,Its a coincidence,

Hi Faizal,

Its a coincidence, actually one of my customer just called me and told me the same observation which you have. I was searching CSC and found couple of below good discussions, these discussions may help you.


I will work out on it today evening and will share my findings.


Check the CSS applied to CFA.

Check the CSS applied to CFA. Does it has access to that calling party transformation pattern ?
