When a user A calls user B, which in turn transfers the call to user C (attended transfer), then the callerID of user B is shown on the display C although user C is now connected directly to user A. How can I get asterisk to update/change the callerID on the destination leg?
I tried to set sendrpid/trustrpid in sip.conf, which unfortunately showed no effects.
Can anyone help me? Many thanks in advance!

By the way, I’m using snom-phones with Asterisk 1.6 branch.
Snom use P-Asserted Identity, so you’ll have to set sendrpid=pai, not sendrpid=yes. Go ahead and set trustrpid and sendrpid in the general section as well as in the peer definition for each peer. It should happen automagically.
