I don't think ooma can do this. same DID, multiple devices.

Ah. Sorry. Carry on

grandcentral IS google voice. It took them four years to re-release it. :-)

Doesn't solve the issue of ONE DID to simultaneously ring multiple devices with the SAME DID.

Apologies - I forgot that I actually use Talkatone to connect to my GoogleVoice account on my iPhone via Wi-FI vs. the google voice app (which still dials over AT&T). I do not use it that much.

I have used Skype (SkypeOut) quite a bit and have been happy with the results. Use it often overseas as well. But have never gone to the point of getting a SkypeIn # so people can reach me.

Neither will solve your ring both places simultaneously desire. I have this setup at work -- same phone extension rings two physical phones at two buildings (though I think one is hardline and the other is VOIP). And I can open up a desktop SIP client from anywhere in the world (which I believe turns off the VOIP extension). But short of setting up your own small VOIP PBX and setting up your phones as different extensions with the same number, not sure the consumer services support this yet.

Nevermind

Look, the whole point here is the difference between ringing the SAME DID at multiple locations (which I do not think is possible) and ringing multiple numbers are various locations (which everything in the world can do) The reason that one cannot have the SAME DID attached to multiple devices is that the unique DID is used for ROUTING, and E911 and PORTING and BILLING. If I could have the SAME DID ACTUALLY on multiple devices how could E911 work? It couldn't. It wouldn't know where each device was actually, or from where the 911 call was coming. Now, of course I can move ANY device but the point is that ONE device gets ONE DID at ONE TIME.

Here's how it works

The 911 call does not come from the same DID. For example, suppose the customer has a UK DID, then he has simultaneous calling, do the emergency services rush over to the UK? No.

So the customer has 1 US DID, that rings in two or three locations. Each location has its own VOIP number which is in turn registered for 911 services and calls to 911 from that number do NOT send out the DID unless of course it is from the line where that DID is registered to.

So you have VOIP#1 (primary which has a DID pointing to it) You then have VOIP#2 and VOIP#3 which are configured to ring simultaneously.

As I said yesterday, my provider does provide this service.

Anyone, show me ONE service that allows the SAME DID to be assigned to MULTIPLE DEVICES? Just one. NOT simultaneous multi-ring to multiple DESTINATION NUMBERS or multiple FORWARDS to MULTIPLE SEPARATE NUMBERS, but SIMULTANEOUS RINGING of the SAME DID at MULTIPLE DEVICES SIMULTANEOUSLY CONNECTED. Just one, please.

I already posted a link
Or did I imagine it?

simultaneous ringing is not the same thing as having the same DID at multiple locations. SR requires simply MULTIPLE DID's and then all get targeted when A or ONE DID is called.

The OP didn't ask for the same DID at multiple locations, the OP asked for the same DID to ring simultaneously at 2 locations.

SR in this example requires only one DID, which can be his primary DID at his home address, to ring simultaneously at his vacation property

That is what he wanted isn't it?

Yes -- but the pint was raised that if he dialed 911 from one of the instruments with one being in Maine and one somewhere else, the responders wouldn't know where to go. That can certainly happen if both instruments are part of the same virtual PBX with a single DiD configured.

Contrary to what was posted above, this is configuration is certainly possible. The only question is what are the requirements associated with location/identification and emergency services. The requirements are discussed here. One solution is to assign an extra DID with the proper alternative address associated with it that isn't advertised by the PBX except in the case of a 911 call. Extra DIDs are only a few dollars a month (though some providers may charge a lot more).

Part of the process of setting this up involves the customer affirming that the location information is correct and the customer keeping it updated. This is why if the OP moves his Vonage phone -- he's supposed to tell Vonage where he is so they can (among other things) update the 911 database.

No problem because each device has to have its own account and the 911 service would be linked to that account not to an inbound DID

That depends on the implementation of the service prvider and on what the customer does with/without telling that provider.

Have a look at www.sipgate.com
I use them since a few months, as well as their german affiliate sipgate.de.
Assigning severals devices to one "physical" number is no problem for sipgate.

Nice ui ( http://awesomescreenshot.com/0b9klgi4c ) + no running costs (apart from outgoing calls.

I am using sipgate.com to receive calls on my US number in germany, really great quality!


EDIT: Sorry, no number porting - at least I couldn't find something about that on their website. You could solve this by using google voice and then forwarding calls from GV to the sipgate number.
