[OpenSIPS-Users] Why am I gettin error to terminate long calls and not short ones? Why it is "Ignoring callid"?

[Răzvan Crainea]

Hi, Rodrigo!

Most likely A closes the connection to OpenSIPS. You can check that by 
tracing the communication between A and OpenSIPS.
In order to solve that, make sure that the TCP keepalive[1] is enabled. 
Also, you can use the dialog pinging[2] feature ('Pp' flag to 
create_dialog()) to keep the dialog connections open.
