Hello Dmitry,
What you want to do is called (in SIP) serial forking. Use
failure_route{} to catch the 488 and to add a create a new branch (with
modified body) .
See: http://www.opensips.org/Documentation/Script-Routes-2-3#toc3

Hello all,
Could you say how can I re-send INVITE with changed SDP to B-leg after
receive 488 from it?
Call flow:
-> A-leg INVITE
<- A-leg 100
-> B-leg INVITE
<- B-leg 100
<- B-leg 488 – I catch it, and want to send INVITE again with properly SDP
-> B-leg ACK
<-A-leg 488
-> B-leg ACK
Thanks for any advice.
Cheers!
