Obi110 Google Voice -> Asterisk -> Handset?

(1/2) > >>

tanders12:
First off I'd like to thank Ad_Hominem and MichiganTelephone for the excellent guides and posts they have made so far which were very helpful getting me up and running.

Now, I'm trying to configure my system so that when I receive a call on SP1 (currently Google Voice), it gets routed through SP2 (Asterisk), and Asterisk does some processing (IVR, MOH, etc). This currently works, however, I would like to have the option in the IVR for the caller to be connected to the handset plugged into the Obi110. I'm trying to figure out if this is possible and if so how it would be accomplished. I tried having Asterisk SIP dial the Obi110 but it said all lines busy, I'm assuming because SP1 and SP2 are currently in use: SP1 connected to GV and SP2 connected to Asterisk. Any ideas?

Thanks

tanders12,

Welcome,

Perhaps a different approach would work. Since the GV call hitting the OBi has no direct value to the caller because you want it going to the PBX. Then consider this call path by setting the GV as a Trunk on the PBX. You can use Simon Telephonics ( https://simonics.com/ ) to connect GV via sip credentials. The OBi can hang off the PBX as an extension. Before the call hits the OBi you can process the call any way you want using the PBX features.:

GV->PBX->OBi

QB,

Thanks for the reply. You have quickly brought us to my true goal. I avoided mentioning this in my original post to reduce the complexity of my question. Eventually I need this to work like this:

PSTN -> Obi110 -> Asterisk -> Obi110 -> Analog Phone

I'm just using GV to test because I don't currently have a PSTN to test on. I figure if I can make this work with GV it will work with PSTN. Now I realized that in this case I could do:

PSTN -> SP1 -> Asterisk -> SP2 -> Analog Phone

But I'm trying to find out if there's a way to do 2 connections between asterisk and SP1 or SP2; one from Obi to Asterisk, the other from Asterisk back to Obi.

Did I explain that in a way that makes sense?

You may not realize that the OBi110 can be set up as a trunk, implying that the call path that I suggested can be used to create your use case.
PSTN -> Obi110 (Asterisk Trunk) -> Asterisk -> Obi110 (extension) -> Analog Phone

Here is our friend Mango explaining how he set it up.
Using an OBi ATA as an FXO port or Google Voice trunk for Asterisk or your IP Phone

But is there no way to do this with GV instead of PSTN? ie can you have 2 simultaneous calls on SP1 at the same time?
