Google voice incoming & outgoing work but not callback

[skomes]

Hi, I'm setting up PIAF with Google Voice on a VPS. The VPS image uses PIAF 1.7.X and I setup Google Voice by downloading the module and installing through FreePBX.

I managed to get both outgoing and incoming calling working.

When using a softphone, I can dial out to anywhere, and when calling in, I can get the server to hang up on me in preparation for a callback, but the callback itself never occurs.

I can see my call coming through in the log but no call going back out to me.

I can't figure out why.

If I set the inbound route to DISA, it works fine, I call in, enter my pin and I can dial out.

But if I set the inbound route to callback, I call in, it hangs up and then never calls me.


My setup:

Inbound Route
Destination: Callback

Callback
Callback #: I've tried setting this to my # and leaving it blank, neither works
Delay before callback: 0
Destination: DISA


Again, I can see the incoming calls on the logs, and even though outbound calling works, I can do it from my softphone or DISA, I can't make it call me back.

Any help would be appreciated.

Oh and caller ID seems to be working fine, as my number when I'm calling in is correctly recorded in the Asterisk log.
