Hello, I have a big problem with the retransmissions. In my tests sometimes the retransmission handler doesn't seem to work properly and it resends the INVITE after receiving a final response. Moreover it doesn't respect the time-out (instead wait 1 second it resends the packet after few decimal), but this is a minor item.
An example: INVITE sip:31203 From 32201
UA1(32201) ---> SER ---> UA2(31203) INVITE UA1 ---> SER ---> UA2 Trying UA1 <--- SER 183 UA1 <--- SER <--- UA2 480 UA1 <--- SER <--- UA2 ACK UA1 ---> SER ---> UA2 ... Other call.
After 0,5 msec SER sends again the first INVITE to UA2: INVITE SER ---> UA2 183 SER <--- UA2 etc.
In the attached zipped file there are the syslog, the ser config file (only the relevant parts) and the ethereal captures related to this example.
Some additional information: SER version is 0.9.2, compiled for arm. In my scenario SER and UA2 are on the same box. In LAN_capture.cap file there is the message flow between UA1 and SER, in lo_capture.cap between SER and UA2.
Can someone explain me this behaviour? Maybe something wrong in my config file? Note that I use t_lookup_request, t_newtran, t_forward_nonack_uri in order to recognize retransmitted INVITE, could it be here the problem?
