Asterisk + CUCM 8.5 + Google Voice

Hello all,

I have been working off and on with a complex project, trying to get my PBX in a Flash 2.9 to work with my CUCM 8.5 and connect to google voice.  Simply put:

GOOGLE VOICE------>PIAF<----SIP TRUNK---->CUCM<----IP PHONES

I have achieved outgoing calls from the IP phones but the incoming calls still fail.

Logs show call from GV Trunk inbound then sent to the SIP trunk, the destination digits are "tdial" and it is listed as answered.  On the phone you hear "Google Voice Subscriber you are calling is not available."

The config I am currently tinkering with is to have a DN on the CUCM (1999) that is going to terminate all incoming calls.  This is the config on the PIAF:

Outbound Routes

TO GV

9|1NXXNXXXXXX

Matches Routes = GV

TO CUCM

EXACT GV PHONE NUMBER

Matches Routes = CUCM

Incoming Routes

Ring Groups To CUCM 1999

I have also configured the SIP Trunk to be included in the Generated_CSS_I_E Calling Search Space (where all my phones are attached).  I have messed with incoming digits being striped and I am out of luck.

Anyone done this before or even have an easier solution for this?

I am also just wondering if there is a tool or log that I can see the digits that are incoming to the CUCM so that I can see if I need to do digit translations or strip digits or what.
