If you can temporarily suspend spoofing (not block CID) or use another DID, it can be setup to go directly to VM.
Thanks for your input. Just for clarification this is in no way a problem for me. I have a smartphone with me at all times and get notified via text and email when anyone calls or leaves a voicemail in my GV account and then listen to the message on my smartphone.
I am just trying to anticipate potential problems come May 15th (or whenever) when thousands of OBIs will stop functioning. Specifically, I am thinking of WAF (wife acceptance factor). Consider this scenario: husband configures Obi with new ITSP and spoofs outgoing CID with GV DID and is gone all day at work. Wife is home and does not have cell phone or computer handy. Not only will she not get a stutter tone or MWI she may very well be completely unable to access GV voicemail at all (if Obi connected phone is her only option). Me thinks this kind of a situation will not pass WAF.
I'm confident that correctly-implemented spoofing works correctly with Google Voice. The problem is most likely that your ITSP is doing it wrong, or is only spoofing/substituting the number on SIP-to-SIP calls.
Important to know: there are no settings on your OBi that should be involved in spoofing. Properly done, it's provisioned by the carrier, and not by sending a spoofing value via a parameter on your SIP device.
In fact: ALL PSTN telephone carriers are provisioning an arbitrary phone number on your outgoing circuit when they provision your account. They can enter any number they wish, and the act of provisioning it is separate from configuring PSTN switch routing for the inbound number, which is usually the same, but doesn't have to be. Properly implemented, the ITSP needs to be sending your calling number out over the PSTN with your number in the correct format.
This isn't some massive problem that is going to impact thousands of users on May 15th. I don't know how to diagnose your issue further at this point. All I know is that it's your carrier's fault. I haven't personally tried those carriers, but I have spoofed my caller ID successfully on many others. I use Callcentric, and last week, I set up Localphone to try out their outbound service, and both spoof my number properly. When I used to use Sipgate, their spoofing almost never worked right. It caused symptoms similar to yours -- calls that rang forever, or went into a black hole of silence, or got an error recording.
If you do believe there is something on GV that is contributing to this, then please post a screenshot of this page:

Now on Vestalink, I'm able to: "Temporarily Disable number spoofing by pre-pending 03" before my Google Voice phone number to access my Google Voice Mail.
This was announced as a Vestalink Beta Program feature but it worked for me today as a regular user.

If you call your GV number with the same GV account, you will go directly to VM.

This is configurable on your Google Voice settings page, to either go directly to VM, or to ring first and need you to barge in by pressing *
Where is this setting?
I only see this option for forwarding numbers, not on the GV number.

Yah, it isn't obvious. It's configured on a number-by-number basis. For example, you may have a home phone number and a mobile number configured as forwarding phones. You may want to directly enter your VM menu when you call your GV number from your mobile phone, but you want your home phone to ring, so your family can answer when you call.
First, go here: https://www.google.com/voice#phones
Next, click the Edit button under your forwarding phone number. Next, click "Show advanced settings". Now, you'll see a section for "Voicemail access". Here, you can toggle the setting to either behavior.
Security warning: never select the option to go to VM without requiring a PIN. With that enabled, anybody who spoofs your caller ID can get into your VM (remember the scandals in the UK over the tabloids accessing the Royal's VMs?).

I don't think we are talking about the same thing.
You are talking about forwarding numbers calling your GV number.
I'm talking about using your GV number to call itself.
When I use my GV number to call my GV number I go directly to VM.
I checked the Voice Access option on the GoogleChat forwarding number and it is set to "NO", so this doesn't affect the above.
