Does the Grandstream GXP2200 access Google Voice via the XMPP protocol that apps like GrooVe IP were using to latch onto Voice? When Google went from Talk to Hangouts, they transitioned away from XMPP and will shut it down on May 15th 2014.

So does anyone know if we will be able run Google Voice and make calls from it on the Grandstream GXP2200 past 5/15/14?

Did someone figure out how to use the handset using Google Voice? It was previously reported that it only works via speakerphone.

Thanks to all! Happy New Year!

[WM: At the moment, our GXP2200 solution uses GrooveIP which relies upon XMPP. The Hangouts client for Android currently does NOT support regular PSTN calls; however, the Hangouts client for iOS does. If Google in its infinite wisdom decides to add this functionality to the Android Hangouts client, then that would be a suitable approach for free calling with the GXP2200 down the road.]

We currently have 8 POTS lines at a doctor’s office. We use four line analog phones, calls that come in on the main number ring on the 1st through 4th lines and these lines are connected to the 2 receptionist phones and the nurses phone. The 1st two lines are also connected to the business office phone – and so on.

I’ve come across the concept of ring groups (I’ve also seen shared call appearance) – can I assign each line on the Grandstream GXP2200 (or the Aastra 57i) to separate extensions? I’ve tried searching for an answer & have had no luck.

My idea would be calls coming in from the 1st DID would be mapped to the 1st lines of, say Group A, the 2nd DID to line 2 of Group A, etc. Hope I’m making myself clear.

Also, do ring groups have problems with caller id as SLA does in Asterisk?

[WM: CallerID works fine with Ring Groups. And the GXP2200 can support six separate SIP registrations so there would be no problem setting up what you’ve described.]

There was a post in 2008 here (Nerd Vittles) about Asterisk and the Digium Conundrum.. in it, FreeSwitch was seen as a silver lining to the nightmare that is Asterisk upgrading/breaking maintenance cycle.

Since then, cool projects like GXP2200 are still based on Asterisk.. why? Surely it’s not better performance, so is there some inherent feature / architecture paradigm that is holding back FreeSwitch adoption?

Saw your comment on the pbxinaflash forum Ward, and was wondering what the Incredible PBX VPN was all about? I am interested in having a VPN endpoint at or beyond my router, and was wondering if you are doing this already in the raspberry pi as a VPN endpoint?
Thanks,
Karl

Here's a quick tutorial that walks you through building 2-minute Android desktop apps to manage any Asterisk server including Incredible PBX.

Hey I am really interested in using the GXP 2200 phone, anybody actually using it in a 50 plus user office? We are in the process of building a new office and I would love to switch over from our avaya pbx, but I love my job more. lol

Alfred: would the POE adapters for the old Nortel i2004 phones work to power the pi?

Now if someone could figure out if you could draw power from the POE input in the phone to the Raspberry Pi. Then no wires except for the one CAT5 cable.

[WM: No POE support on the Pi (yet). Sorry.]
