hi,
i’ve a strange issue.
All Calls (incoming and outgoing) are working fine for three days.
3 days later, the incoming calls get a not-in-service message from the pbx.
After a “sip reload” incoming calls working fine again for three days.

You will need to ask the person who included the above in the dialplan how they detect those conditions as you are already on the path to"no servce" at that point.

The message may be wrong and you may simply have allowguest and a call originating from an unregistered peer.

Thank you david551, but both options are enabled

  • Allow Anonymous Inbound SIP Calls
  • Allow SIP Guests

The strange thing is, after sip reload it works fine again.

You have allowguest, and the peer presumably lost its registration.

I’d strongly advise against allowing guests.

ok, thank you for the hint - i miss understood you.
I’ll change the settings and it seem’s for me it could be a problem with the NA-PTR resolution.
