Google Voice forward to Asterisk PBX

By |April 2nd, 2013|Categories: How To|Tags: , , , |6 Comments

I recently started at a new place of employment and wanted to port my cell number over from Sprint which my old employer used. This was okay with them so I ended up porting the number to my Google Voice account. I wanted to forward it to a new DID that I would get with a SIP provider and run my Asterisk PBX from that.

I then got a new phone from the employer and installed a Android SIP client on it. Registered the extension to my Asterisk server and started some testing.

Well sometimes the calls work fine, and sometimes Google Voice ends up just sending the call to the Google Voicemail. I wanted to fix this problem, and I believe I have found the solution if your trying the same thing.

On your incoming route in Asterisk for your Google Voice number, you need to setup a wait period. In the incoming route screen of FreePBX there is a field that allows you to wait before picking up the call. I changed this from an empty default field to 2 seconds.

I then checked the box above it to enable Signal RINGING.

It took me a while to figure this out, but I now have my incoming Google Voice number coming to my Asterisk server, hitting the incoming route, then an IVR, then to various extensions and ring groups.

    Thank you!!! Thank you!!! Thank you. for posting this!!! I have been racking my brain trying to figure out why I could see in the logs that my asterisk box was picking up and playing the IVR but google voice kept ringing that would eventually go to GV voicemail. I actually had to change my wait period to 3 secs.

      Happy to help another, sad to hear this is still an issue. I now believe this might not be an issue, but a Google configuration option from their side. It has been like this for a long time.
