Hello,
I'm using Kamailio as SIP redirect where SBC sends INVITE packet to kamailio and "302","Multiple Choices" is sent back to SBC.
What I want is to modify the URI part in the To header of the Multiple Choices packet sent from kamailio. I tried to use uac_replace_to("","sip:$var(cdpn)@$td") where $var(cdpn) is already defined in the routing logic, but it's not reflected and the original TO URI is sent instead.
Any help to handle this issue is much appreciated.
Regards,
I used append_to_reply function to rebuild the To header, but the problem is that the old To header stays there even if I use remove_hf method to remove it.
What I’m doing wrong here? My logic is set inside a route block.
Regards,

As I got, you're using send_reply() function. I'd suggest you to form 3xx message manually and than just wait for ACK.
