send incoming SIP calls to Google Voicemail with OBi202

Maybe you should consider another service for voicemail.

Callcentric has a free account with voicemail and I believe you can pass the incoming callerid to them.

I currently have voicemail set up on my main VoIP provider, voip.ms. Their voicemail service is quite OK (I think standard Asterisk-based), but not nearly as full-featured as Google's.

I've tried out Callcentric's as well (I use them for some services) but it isn't as good as with voip.ms.

Thanks for the suggestions, they are much appreciated.

If sending the caller id to GoogleVoice is important to you and you are willing to pay for the call I believe it can be done using sip.  With voip.ms, I believe it can be done in the following manner.  From voip.ms you obtain a "Virtual Number" as an incoming number and with the voip.ms "Manage DID" page you forward incoming calls to this virtual number to your GoogleVoice number with the voicemail.

Then on the OBi you configure the delayed call forwarding to send the call to the voip.ms "Virtual Number" using the sip uri address that you obtain.  On the OBi ITSP Sip Profile you enable X_SpoofCallerID so that your bridged outgoing sip uri call will pickup the incoming caller id.  As you know the voip.ms VirtualNumber has a 25c monthly fee plus they charge one tenth of a cent per minute for the incoming call and of course their outgoing per minute charge for the call to the GV number.

with the voip.ms "Manage DID" page you forward incoming calls to this virtual number to your GoogleVoice number with the voicemail.

I think in that case the call would still go by PSTN, from voip.ms to Google? I had previously tried setting my main DID at voip.ms to fail over directly to my Google number, when calls are not picked up at the OBi. That way the CID is passed on by voip.ms -- which in practice, seemed to work for about 25% of calls. And the voice quality suffered noticeably due to going from digital > analog > digital.

Still, I will try your suggestion -- sounds like it could help reliability of the CID at least.

Yes, the GoogleVoice number is a pstn number and GoogleVoice has no other way of receiving a call unless, of course, it is their own system doing the calling.  In the latter case they have a policy of only using their own caller id number. 

I would think the difference between a direct fall over to your Google Voice number from voip.ms from routing the call thru the OBi would be the delay you are configuring to allow the call to be picked up by answering the call with the handset on the OBi unless voip.ms also allows you to configure that delay.  I wouldn't think the caller id handling would be much different.

I would imagine that voip.ms routes the call thru some other company's interface to the PSTN on the way to Google Voice and if there is a caller id delivery failure it would be at that point.
