Gateway Calling for Google Voice?
azrobert:
My VPN knowledge is limited, so I won't be much help.
This is how to route Callcentric to an OBi via IP.
In Callcentric setup a Call Treatment.
Select "This Number"
Set the value to 0@xx.xx.xx.xx:pppp
Replace xx.xx.xx.xx with your public IP address
pppp is the port number of the OBi202's SPx where you want the call routed.
The port number is the SPx Service X_UserAgentPort
In your router port forward the X_UserAgentPort to the OBi202
You also need to port forward the RTP ports
The RTP port range is found here:
Service Providers -> ITSP Profile x RTP -> LocalPortMin thru LocalPortMax
I use FreeDNS for DDNS, but there are other free services.

Replace your IP address in the Call Treatment with your DDNS name plus port#.
Some routers have the ability to update the DDNS address.
There is an OBi hack you can use:

You can route outbound calls from the Linksys ATA to the OBi202. You point the Linksys proxy to the IP address of the OBi202 and the port# of one of the SP trunks then add routing rules to the X_InboundCallRoute of that SP. The ATA must be able to call without registration. You can point both lines on the Linksys to the same SP and have outbound routed to different GV accounts by line#.
Edit:
People have added changes to block SIP Scanners. These changes might also block calls from Callcentric.

I assume that I would need to use the local web access for this?
In any case, many of these steps are a bit beyond my current knowledge. Is there some tutorial that explains the steps in more detail?

Do you have a link for this?

If I understand you correctly, I connect my phone to the SPA2102 (or SPA3102) to receive the calls from Callcentric and then send the outgoing calls to the Obi202?
EDIT:
Is Gateway calling the same as saying that the ATA can call without registration? Maybe I am misunderstanding what gateway calling means? I understood it to mean that I would press ##2 (for example) to call out on a number (including GV) without having to use an SP and register. Is that correct?
Routing the calls from the Linksys to the Obi202 may actually help as it would free up two SPs on the Obi202. However, I am not sure if this is supported by the SPA2102 or SPA3102?
Is there a good forum for Linksys ATA support?
p.s. I really need some way of learning all this stuff. Any references?
azrobert:
I think we should try the SPA2103 solution first. If you define CC#2 on the SPA2103 then you can delete that line from the OBi202, making room for another GV.
The problem with this solution is you need a 3rd phone. I think the SPA2103 has 2 phone ports and can have 2 provider definitions. The solution is to move all the OBi202 phone2 functions to the SPA2103. I suggest defining the OBi202 as provider1 for outbound calls and provider2 as CC#2 for inbound. The OBi202 can forward inbound GV calls to the SPA2103.
We can setup a test to see if this will work. This setup will not affect your current setup.
Define the OBi202 on the SPA2103 as provider1:
Proxy: xx.xx.xx.xx (the ip address of the OBi202)
Proxy Port: 5083 (X_UserAgentPort of SP4)
Password: anything
Enable inbound and outbound without registration.
I don't know what else is needed on the SPA2103
Use OBi Expert to make sure SP4's port is 5083
Voice Services -> SP4 Service -> X_UserAgentPort
Do you know how to use OBi Expert? See below.
Attach a phone to port1 and dial any number.
The OBi202 should ring.
If it rings, you will be able to make outbound calls on the SPA2103 with some config changes on the OBi202.
I'm going to stop here before spending too much time and see what you think and if the above works.
To enter OBi Expert from the Dashboard click on the gear ICON to the right of your OBi202 then select OBi Expert Config, confirm and select Enter OBi Expert.
To navigate click on the titles with the + then click on a sub-title.
An example: click on Service Providers then click ITSP Profile A General.
To make a change BOTH boxes to the right of the value must be unchecked.
When all changes are complete on this page, click Submit at the bottom of the page.
OBiTalk will download the configuration changes to the OBi and reboot it.
Wait until this process is complete before continuing to make another change on a different page.
Also uncheck both boxes to just view a value.

Thanks azrobert,
I will try what you described above shortly. Some comments first though:
1. I don't have a SPA2103 but a SPA2102 (I assume it is a typo?)
2. I can only use two phone lines. I am not sure why I would need three?
I expect it to work like this:
Phone Line 1 on SPA2102:
Incoming call from CallCentric#1
Outgoing Calls forwarded to OBi202 and sent to GV#1
Phone Line 2 on Obi202:
Incoming Calls from CallCentric#2 (using SP1)
Outgoing Calls to GV#2 (using SP2)
Outgoing Calls to GV#3 (using SP3 and accessed by speed-dial; e.g. by pressing #3)
I assume that I can use speed dial to dial out on GV#3 if I "set it up" by using SP3?
By the way; is the correct term "provisioning" when I "set it up" with SP3?
azrobert:
1. Yes, it was a typo.
2. I was referring to only moving CC to the SPA2102 then you need a 3rd phone on the OBi202 phone1 for GV outbound. Moving GV outbound to the SP2102 fixes this.

What are SPA1-3? Do you mean SP1-3? What would the speed dial do? Do you mean a dial prefix? You can use a dial prefix to access SP3. You can modify the config to use any dial prefix you want.
