see, you have gave me a new direction to think about this, I think it is work for carrier, so some small ITSP, most of them use "From" for identification.
Thanks for your answer. kaiser

If only one forward number in AVP array , this code working fine, the issue will happen if multiple forward number trying, ( forward 2nd,3rd ...number) the UAC module will restore from header in 200 OK of its following message when a UA answered, we will have a duplicated "from header" in 200 OK (sending out opensips). It means we will have 2 "from" headers (in 200 OK) to caller, if 2nd forwarded callee answer.
Caller ---> Invite ---> opensips ----> UA 0, no answer ----> UA 1, no answer ---->UA 2, answer <----200 OK <---200OK<---
this 200ok will have 2 "from" header.
Are you sending these calls to a SIP/PSTN gateway? if so, it easier to add a P-Asserted-Identity or Remote-Party-Id header containing the callerid you want to show to the remote.
