I have a slightly strange problem with my FreePBX installation. Calls between any extensions work with audio on both the originating and destination extensions. Calls coming in from PRI trunk works perfectly with two way audio on both the originator and destination extensions.
Problem occurs when I try placing a call from one of the hardware voip phones to outside using the PRI Trunk. The call connects (as in there is a ring on the destination phone), but there is no ringback heard on the originating extension. Also once the destination end picks up, originating extension hears no audio though destination end hears the audio perfectly. This is happening on all hardware voip phones (mix of two different models)
The problems goes away if I use a softphone (Zoiper) for dialling through the PRI trunk. In this case, audio is heard both on origin extension and destination. Ringback is also heard on the origin extension.
I have tried disabling the firewall on the FreePBX server, but it was of no help. I am fairly new to FreePBX, so this has got me stumped.
Installation details:
Distro: FreePBX STABLE 10.13.66-17 64bit
Asterisk Version: 13.12.1
Pri Card: Digium - Wildcard TE121 Card (E1 line)
Voip Hardware Phones : Audiocodes 310HD & Akuvox SP-R50
Voip Soft Phone: ZoiperAll devices and FreePBX are on same network, without any firewall between them.
FreePBX is installed with a Digium TE121 PRI card. Card seems to be configured correctly (auto configured, just changed the Switch Type to EuroISDN) with no Alarms. Configured 18 extensions, 10 Akuvox, 6 Audiocode, and 2 softphones (Zoiper).
