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.

Dear OpenSIPS users,
In my hardware, with IP = 192.168.0.101, I have OpenSIPS and softphone
A. Thre is softphone B also, in another hardware.
A calls B.
B accept the call.
After *_t_* minutes...B hungs up the call.
In this moment, A enters in a wrong state, because OpenSIPS reports a
problem and probably due to it the proxy doesn't communicate with
softphone A in such moment. So, my softphone A considers that the call
is not ended.
See what OpenSIPS reports in this moment:

If *_t_* is just few minutes, let's say 2 minutes, there is no any issue.
However, if *_t_* is bigger, let's say 4 minutes, his issue is present.
What is happening here? Can someone give some help, please!
Any hint will be very helpful!
