Re: [SR-Users] Kamailio not updating CSeq after uac_auth() for ACK

Hi, I have updated Kamailio to 5.4 still there is an issue with Cseq of cancel in case of cancel it is not increasing cSeq here are details 1. proxy a sends invite with CSeq: 102 INVITE and proxy b route it to asterisk with CSeq: 102 INVITE 2. asterisk sends 401 Unauthorized with CSeq: 102 INVITE and proxy b sends ACK with CSeq: 102 ACK 3. proxy b sends invite with CSeq: 103 INVITE and asterisk sends 100 Trying and 180 Ringing with CSeq: 103 INVITE 4. proxy b relay to proxy a 180 Ringing with CSeq: 102 INVITE 5. proxy a send CANCEL with CSeq: 102 CANCEL and proxy b sends CANCEL with CSeq: 102 CANCEL to asterisk 6. Now asterisk is sending 481 Call leg/transaction does not exist uname -a: Linux example.com 4.15.0-124-generic #127-Ubuntu SMP Fri Nov 6 10:54:43 UTC 2020 x86_64 GNU/Linux kamailio -v: version:
