I have changed the following tm parameters in order to have an timeout INVITE equal to 20 sec (20000 ms). # ----- tm params ----- # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 0) # default retransmission timeout: 20sec modparam("tm", "fr_timer", 20000) # default invite retransmission timeout after 1xx: 120sec modparam("tm", "fr_inv_timer", 120000)
However, the timeout is ever 3 min (180 sec.) In accord to tm module the timeout is defined only by "r_timer" Then, I don't know where is the problem.
Thanks a lot for your help.
