I wonder if anyone here has had similar issues to me with incoming calls on PSTN (Obiline) answered by an extension to FreePBX off the PH1 interface on the Obi202 being disrupted by intermittent DTMF dial tones?
Any help would be appreciated
- There is a SIP trunk from the Obi to the FreePBX (RasPBX) all on the same gigabit switch.
- PSTN is a virgin media line.
- Incoming calls to other extensions on the FreePBX do not appear to have this problem.
I also have distorted choppy audio if I connect the ObiLine through USB (AC powered) hub with my ObiBT USB adapter.
