ATA as a 2nd OBi phone port
azrobert:
I would like to share my setup with the forum.
I'm using an ATA as an almost full function 2nd OBI phone port.
First, I want to give credit to hwittenb with this post on Dslreports:
http://www.dslreports.com/forum/r27101955-Using-one-ATA-as-proxy-of-another-one
Second, I apologize if this was covered by another post. I could not find anything.
My hardware:
OBi110 and a Grandstream ATA on the same network.
OBi110 config:
sp1 = GV
sp2 = sip provider
sp2 X_InboundCallRoute = {(My_ID)>(1?xxxxxxxxxx):sp1},{(My_ID)>:sp2},{ph}
ATA config:
Server = 192.168.1.xxx:5061 (IP addr of OBi)
User ID = My_ID
Register = no
Any 10 or 11 digit call on the ATA will be routed to GV. All other calls will be routed to the sp2 provider.
GV supports 2 concurrent outbound calls, so you can have calls on the OBi and ATA at the same time.
The OBI is acting as a proxy server to the ATA.
Inbound calls to the OBi can be routed to the ATA's IP address.

I don't understand what you are accomplishing with this.
Why don't you just use a Splitter?

You can not make/receive multiple calls with a splitter. With the splitter you are limited to one call. Connected via splitter you can share the call with the other phone (party line/conference).

I've tried to replicate this capability using a softphone.
I don't understand what else might have to be configured on the Obi so that the "my-id" field can be used, and also where the 5061 listener port gets configured.
Any suggestions?

I got the X-Lite SoftPhone working with the following config.
OBi110 config:
sp1 = GV
sp2 = sip provider
sp2 X_InboundCallRoute = {(robert)>(1?xxxxxxxxxx):sp1},{(robert)>:sp2},{ph}
X-Lite config:
UserID = robert
Domain = 192.168.1.xxx:5061 (IP addr of OBi)
Register with Domain = not checked
Send Output Via = Domain checked
In my previous example My_ID is any name you want to pick.
The ATA/SoftPhone will send the UserID as the CID.
That is what I'm checking for in the X_InboundCallRoute.
5061 is the default port on the OBi SP2.
If you defined SP1 as your SIP provider then use 5060 and modify your sp1 X_InboundCallRoute.
I haven't tested it, but this setup should work with the ATA/SoftPhone outside your home network.
You would have to setup port forwarding in your router.
Beware, there is absolutely no security with this setup!
