When I try to place a call using GV (TOR) I get
"LOG: channel.call
Error while placing call from xxxxx to yyyyy:
There was a problem with GV: {'data': {'code':20}, 'ok': False}"

(xxxx, yyyy, are my GV number and the destination number)

I'm using a SIP number for call back that is verified with GV and the number is in TOR's 'forward' field.

Any idea why I'm getting this?
