Grandstream GXP2000 and OBi100
Brian01:
Yeah. You could use the ip address of your home, no need for a domain.
It's also a one line hack of the Android system to make the native sip stack work over cell data in addition to wifi. So you could conceivably use the setup over your cell carrier's 3g or 4g for free cell calling. (wouldn't try it over EDGE)
As you say though, the quality would depend on your home connection, cell tower, etc. I've tried VOIP over T-mobile 3g and it works just fine if you're near a nice strong data node.
What I really want is a better dialer. Right now I use the built-in dialer and it asks if I want to use Google Voice or not...then it asks if I want to use cell or internet...two annoying dialogue boxes. We need a dialer with checkboxes and a better default system.
Dale:
yes but the IP address of the home router can change and the no-ip DNS entry ensure that it can be found....
I told my android google voice never to dial calls... GV actually uses the cell connection to call into GV and then bridges that to the call you dialed. So for a T-mobile pay as you go customer it achieves nothing.

I have successfully set up Google Voice on SP1 and am trying to connect my Grandstream GXP2000 to SP2. I followed the instructions in this article:
http://voxilla.com/2011/02/15/how-to-obify-your-ip-phone-no-asterisk-involved-2623
However, the details for registering the Cisco phone don't really apply to the Grandstream phone, which is not registering with the OBi100. Can anyone provide guidance that is specific to a Grandstream phone?
Thanks so much for the link!
I used that great guide to set up a few Grandstream GXP2140's with an Obi202. The problem I'm having is transferring calls between phones. All of the phones have EXACT identical settings (except for the IP address).
If a call comes in and I pick it up on one GXP2140 and I want to transfer it to another GXP2140 how can I do it? I tried using Quick IP dialing, but that doesn't support call transfer (just disconnects the originating call).
I asked in Grandstream support chat, but they weren't familiar with this freaky Obi setup "Didn't you just set up your voip providers settings inside the GXP2140??".... "Ummm, no. Because Anveo limits me to two devices logged in, so using my Obi box as the proxy I can have tons of phones all use Anveo..." so they had no idea how call transfer would work. Any ideas??
Another thing that's freaky. I figured if I set up identical settings in each phone, that the "lines" would be shared on each phone (i.e. if I was on a call on phone1 line1, then on phone2, line one would be lit up red, or at least let me barge into it), but nope. If a call comes in on "line 1" and I put it on hold, I can click "line 1" on the other phone, and I get a dialtone, and can make calls no problem!! strange :)
If you have any information on how I can transfer a call from one IP phone to another one logged into the same Obi box please let me know.
