QUESTION Call answered but extension still has ring tone

[lcsneil]

Hoping someone can help here.
First of all let me explain my setup.

Incredible pbx 2.11.0.32 (asterisk v11.3.0) running on a raspberry pi. (512)

I have an OBHi110 connected to my POTS line and use voipcheap.com for my VOIP outgoing trunk.
I have a number if incoming SIP trunks ranging from localphone, goldfish.ie and sipgate (co.uk)

Two pap2 units running three extensions on my local lan.
I then run two IAX extensions. One on my mobile using the Zoiper client and an Atcom AG198 box on the
Internet running an extension on a remote site.

My problem. I am currently in the remote site (different continent ) and
when I dial out via the AG98 box and the dial rules use the OBHi110 box (i.e. the POTS line) it
all dials out Ok But when the dialed number answers the voice channels
aren't sent through to the phone and all you hear is ring tone still and the person you are calling just hears silence.

However if I use the mobile and Zoiper client all is well (I have even changed the credentials on the Zoiper client to use the AG198 extension just to check config).

Similarly if I use the Zoiper client to call the Atcom AG198 client internally then all
is well.

If I use the AG98 line to call a number that uses the Voip trunk instead of the POTS line again all is well.

So it is only the combination of the AG98 and the OBHi110.

Looking at the asterisk logs it shows that the calling is ringing and then answered. But no further info. How do I see what signalling info is sent to the remote IAX extension?

Anyone any ideas how to fault find any further.....

See log below (AG198 is ext 197)
