[cisco-voip] Fw: Calling Party Transformation

[sarjot at googlemail.com]

Hi guys sorry i hit the send button early, please see the full message below. 

Need help!! We have direct SIP Trunks to our ITSP (Route Group, Route List, SIP Trunks) to dial to the PSTN users dial 9 and the PSTN number. The problem we have is when users forward their calls to their mobile phone or external numbers, the calling party number shows a leading 0 infront of the number (090) this only happen if the call is coming from externally, with internal it works fine. 

For example if user A does call ForwardAll to her mobile phone e.g. 907877XXXXXX and user B from external call her extension number which forward to her mobile phone. User A will see incoming call number as 0907888XXXXXX mobile number of user B. 

What is the best way of striping the 90 with calling party transformation, the ITSP is putting a leading 0 at the egress point.
