Hi to all,
I've updated my ser.cfg file as follow.
Essentially I've updated "Call Type Processing" Section, with
introduction of BYE SIP message handlling, and route[2] section.
So SER now reply to BYE message from PSTN Gateway (in my scenario
Phone --> PSTN --> Gateway --> SER --> SIP Phone) just with 200 OK,
but does not forward BYE to SIP Phone.
I hope this may be helpfully!
Thanks,
flavio
