Caller hears no ringing

[JointTech]

People calling in hear no ringing if the inbound route is set to a ring group or extension. My main number goes to a IVR but we have DIDs pointed directly to ring groups and extensions. Caller hears nothing until they get VM or somebody answers the phone.
I tried setting the option for PBX delivers Audio. Restarted the services but still no ringing.

any ideas on what to check?
We have a PRI from Cox and some Vitelity VOIP lines. The Voip lines which are pointd to a ring group do ring... The cox PRI lines dont.

I had the same issue. I was using a Sangoma PRI card. I haven't seen that issue with VoIP trunks or POTS adapters.

So. we need more info on the hardware configuration.

I would say the it is a setting on the PRI gateway. You should review them. It should be cutting the audio path through before answer.

Thanks guys. Once I knew what I was looking for I found this:
http://www.3cx.com/blog/docs/ringback-tone-sangoma/
Then I found NetBorder Express software under program files and found the gateway manager. Changed the setting and I have ringing!!
Now hopefully that setting doesnt break something else.

sangoma, 3cx, cox, no ring back tone
