No INVITE packet from ITSP after restarting Brekeke PBX
After restarting Brekeke PBX, incoming calls from ITSP work. But after a few minutes, incoming calls fail. I captured packets but didn’t find INVITE packet from ITSP.
There are two possibilities:
1. There may be another client which registers to the ITSP with the same account and it is registering to the ITSP more frequently than the PBX. If so, please close the client and re-register the PBX ARS.
2. The broadband router may have closed the external port in a few minutes. If so, please try setting [Register Expires] = 60 or 120 in your ARS for the ITSP. Then the external port would keep open.
