Hello, the 481 is sent by the caller, meaning it doesn't know the call anymore.
To help troubleshooting, you have to send the full sip trace of the call, from initial invite to the bye, including the responses, taken on sip server, in both directions. You can use ngrep, like: ngrep -d any -qt -W byline "sip" port 5060 Cheers, Daniel On 30/03/16 19:14, Humberto H wrote: > Hello; > > Inline image 1 > HOW can I send 4XX to the caller when the callee response to a BYE > message is: > *481 Call leg/transaction does not exist.
