I’m a former Nortel Option 81C Admin who is spending his newfound COVID time hobbying with building a telephony server using spare parts. I am now building and moving to FreePBX from 3CX using mostly the same equipment (3CX is on a RasPi and FreePBX an HP EliteDesk). I have an off-brand 2FXO 2 FXS ATA that has one PSTN connected to an FXO (Trunk 10000 in FPBX) and both FXS are in use (Ext 101 & 201). Using the current config, I managed to get it to work flawlessly with 3CX, which is much less flexible (one of the reasons I am moving away). However, with FreePBX incoming calls get “answered” and immediately dropped. I can make outgoing calls.
I’ve attached select logs from FPBX and the ATA:
It appears it’s not authorizing? This is where I’m getting lost - the two FXS ports are authorizing fine and I can receive incoming calls .
Here are my PJSIP settings for this trunk:
Username = Username is trunk name
Authentication = Both (Tried Outbound)
Registration = Recieve
Language Code = Default
SIP Server = 10.172.20.5
SIP Server Port = 5060
Context = from-pstn
Transport = 0.0.0.0-udp
As a side note, I have two GV lines coming in via an ObiTalk Device - those work flawlessly.
Thanks for any help or insight you can give this noob!
