Calls from PSTN dropped in 30 seconds. No ACK message.

Since the last two weeks I have faced a problem when receiving calls form any PSTN access number. The call is answered normally but is dropped after 30 seconds. I am using SJPhone and before disconnecting the call the phone displays the message "Awaiting acknowledgement". After 30 seconds the call is disconnected and SJPhone shows the message "ACK Timeout". I have tried different PSTN access numbers and the problem is always the same. Calls from other SIP devices work perfectly.

Thanks in advance.
