id not enough to define the AVP that will keep the source and 
destination of each leg, but you also need from the script to populate 
them according to your call processing related to forward. If you search 
on the list archive, there was a post about multi leg call, containing a 
script snapshot.

no, it is not related to redirect processing.

it means that the Diversion hdr you added is not accepted by the GW - I 
had also this problem once and the solution was to remove all hdr 
parameters  - the CISCO GW does not like them.
