However, the INVITE is still forwarded for this branch. So obviously the "outgoing transaction" is not suspended.

May be "t_suspend" is only suspending "incoming transactions"?

I tried to call "drop()". This prevent the INVITE from being sent. But in such case, i have an answer

is sent immediatly to the caller (SIP/2.0 500 I'm terribly sorry, server error occurred (6/SL))

I want the script to wait as expected after my "t_suspend". And in the block indicated by t_continue,

i want to append a new branch.

Any way to do this?

Otherwise, do you advise me to control the list of branch before t_relay? I guess I can access

the list. Not sure how.. so if you have any tips...

Tks
