Hi Răzvan.
I'm still investigating the problem.
Now I'm using the'Pp' flag to create_dialog(), as you had suggested. In this
case I can see that OpenSIPS sends SIP OPTIONS to the 2 peers and they respond

it? That
Ok.
Thank you very much for the hint.
Best regards.

Also, you can use the dialog pinging[2] feature ('Pp' flag to
create_dialog()) to keep
