Call Forwarding incorrect calling number

[@Syed]

Dear All,

I need assistance with the following issue.

I set Call forwarding to my mobile number from my extension and call forwarding is working fine, but I see my extension's DID number on mobile which is causing inconvenience to identify in case of missed call. So, I want to see the actual calling number.

Call Flow is as follows:

CUCM > SIP Trunk > SIP Gateway > ITSP.

Thanks in advance.

Syed..

Can you capture the SIP messaging on the SIP Gateway and post it for us to review?

On the SIP trunk in CUCM go to the "Outbound Calls" section and change the line "Calling Party Selection" to "Originator"

Make sure your ITSP allows you to spoof the other party's number though,,, they might reject the call since you are spoofing another number.

That worked.
Thank you Mikeleebrla.
