Hello,

in this case, you have to perform the update of To header only in branch_route.

Cheers,
Daniel

Hello all,

In my situation, it is possible to call forwarding to registered users multiple times on same leg. For each forward i have to update To uri and i am using uac_replace_to to do that.

But on second relaying, To uri was malformed. On below, Im attaching configuration to illustrate my problem. (version-5.4.9)

First relay - /To: //sip:xyz@192.168.0.51/

Second relay - /To: sip:xyz@192.168.0.51sip:abc@192.168.0.51/

Thanks in advance.
