[cisco-voip] External Call Forwarding

Look at the calling party selection setting on your outbound  
gateway.  It's probably set to something like Originator currently,  
where you want something like First (or Last) Redirecting party.

Hi All,

I have a question about call fordwarding.

Scenario is that when an ip phone is forwarded to an external number  
and another external number calls that ip phone the call is forwarded  
to the external number. When the forwarded call reaches our outbound  
gateway the calling number is the external number that started the  
call and the called number is the external number that which is  
configured for the CFA. Our carrier does not let us use any other  
number then that which is in the DID range so they change the calling  
number to the pilot number of the DID range.

Say the DID range is 123456XX (100 Numbers). Extension 5602 is CFA to  
0456785856 (external mobile). External number 4555598598 calls  
12345602 and it forwards to 0456785856. Currently the calling number  
that shows up on the mobile phone 0456785856 is12345600 (pilot of  
DID). I wouldl like the number to be 12345602. Debugging on the  
gateway shows the calling number as 4555598598 and the called number  
as 0456785856, our carrier does not recognise the calling number as  
part of the DID range so changes it to the pilot point.

Is there anyway to configure the calling number to be the number of  
the phone that forwarded the call instead of the original external  
number?

cheers,

Daniel
