Forward to Google Voice voicemail before 25 seconds default
SteveInWA:
No, that won't work.
I think you are misunderstanding how GV works.
Ignoring OBi devices for the moment... When you set up a Google Voice account, and you obtain your own inbound GV phone number, you add one or more forwarding telephone numbers. By default (with no changes to settings), when an inbound call is made to your GV phone number, GV will ring all forwarding phone numbers for about 25 seconds. Whichever forwarding number answers first "wins the race". Either a human (you), or the voicemail system of one of your forwarding phones, is answering that call. There are two ways to alter this behavior:
If a forwarding phone's service provider supports Conditional Call Forwarding (also known as no-answer/busy transfer), then you would activate that feature, and have the carrier send unanswered or busy calls back to your GV number, where GV would take the VM message.
The "big four" mobile carriers (AT&T Wireless, Sprint, T-Mobile and Verizon) typically support CCF. Many service providers don't support CCF (most land lines and most mobile carrier low-cost subsidiaries or MVNOs).
So, in these cases, the problem is that the phone number(s) that don't have CCF enabled will grab the forwarded call to their own VM, instead of letting it go back to GV VM at the 25-second mark.
To prevent this, you can turn on GV's Call screening function. When this is enabled, GV requires that whoever or whatever answers the call press "1" to accept the call. Since your forwarding phone's VM system isn't human, it can't do that, and GV will take the call back to GV VM.
Phew. Now: OBi devices configured to use GV are actually using Google's old "Chat" system, and are simply treated as yet another forwarding destination, with the same call-handling behavior I described above. If the call is busy or unanswered, GV will take the message. No, you can't change the time interval for this.

I got this to work, but with a problem.
I don't hear the prompt from Callcentric VM service.
This is what I did.
In Callcentric routed extn 101 calls to VM.
Changed the X_InboundCallRoute for the GV SPx Service to:
ph,sp2(17771234567101@in.callcentric.com;d=15)
The d=15 is a 15 second delay.
Inbound GV calls will ring the phone port for 15 seconds and then will be routed to Callcentic.
Everything works except for the audio problem.
Removing the delay fixes the audio problem.
I don't understand why the delay is causing problems.
I'm port forwarding the user agent and RTP ports on SP2.
Anybody have any ideas?
SteveInWA:
That's not what the OP is trying to do. He's trying to loop the calls from GV to CC and then back to (another or same?) GV account and finally to GV VM. Not using CC VM.
azrobert:
Assuming GV#1 is defined on SP1.
Changed the X_InboundCallRoute for the GV#1 SP1 Service to:
ph,sp1(GV2_NUM;d=15)
The d=15 is a 15 second delay.
Inbound GV calls will ring the phone port for 15 seconds and then will be routed to GV#2.
I got this to work.
I think you just have to add GV#1 as a contact in GV#2 and route it immediately to VM

OP: Is there a way to forward back to Google Voice's voicemail before the default Google has set at 25 seconds? I'm aiming for a 15 second delay before going to voicemail.
No. You're sending the call from one GV account to another one. That doesn't put the voicemail message where it belongs, in the account of the number that received the call.
Just follow my instructions to use call screening, and don't worry about the 10 seconds.
