FreePBX to a2billing via DISA no call duration issue

I’m having a problem with calls sent to a2billing through a DISA using a custom context.

Calls are being handle properly with the exception of Call Duration and of course bill information as a result of the 0 duration.

The only that I can see that may be causing the problem is the fact that the DISA is completing the call as non-zero and for some reason a2billing is not seeing the call as completed when in fact it has.

Does anybody have a similar configuration that works using DISA or is this an impossibility?

it does not seem like a unreasonable thing. But have you asked over at the a2billing forums as you’ll have a better chance of somebody there using a2billing along with DISA then here…
