Hi all,
I have a problem when the b2bUA rejects a reINVITE
message with a 488 message (Not Acceptable Here).
Here is the dialog:
UA1 --- (reINVITE) ---> b2bUA UA1 <---- (488) --------- b2bUA UA1 ----- (ACK) -------> b2bUA
When the UA1 receives the 488 message, it sends an
ACK message.
But, at the b2bUA, the Dialog Usage Manager does
not recognice the ACK message as a part of the sane transaction of the reINVITE
message, and it begins to retransmit the 488 message:
trazaDeb | RESIP:TRANSACTION || TransactionUser.cxx:66 || Checking if SipReq: INVITE 150@xxxxxxxxxxx:5071 tid=fb7f865ded1dc6d1b6c8c8acb476fc3a cseq=INVITE contact=192.168.34.23:5061 / 2 from(wire) is for me trazaDeb | RESIP:DUM || DialogUsageManager.cxx:1299 || Got: SipReq: ACK 150@xxxxxxxxxxxx tid=5d49608fbf849b7dbdcb3deaf6de9d42 cseq=ACK contact=192.168.34.23:5061 / 2 from(wire) I don´t know if there is any mistake or it's a
BUG.
Thanks very much in advance.
Here are the messages:
