Configure Polycom OBi200 ATA with Google Voice on Kazoo

[fmateo05]

Hi. A month ago, I have purchased a OBi200 ATA suitable to handle Google Voice numbers.

Currently it is integrated on my kazoo cluster. There are some steps that will be shared and also will update this post. 

After creating the account In the first time setup you should open port 10000/udp on your router forwarded to the Obi200's IP address. 

In this install SP1 is the google voice's linked account, and SP2 is the SIP account linked as Kazoo device ATA

You should set the following routing parameter in the SP2 setting (Obiexpert > Voice Services  > SP2 service > X_InboundCallRoute)

On SP1 setting (Obiexpert > Voice Services  > SP1 service > X_InboundCallRoute), you should set:

sp2(<17862223333>)

Then, 

Obiexpert > Service Providers > ITSP Profile B SIP (this belongs to SP2)

Here you set the kazoo ATA SIP device parameters and also set X_AccessList     to your kazoo's proxy ip addresses.

The google voice profile was defined on the Non-expert user interface just before switching to OBi Expert configuration procedure.
