Is this phone standard SIP and more specifically, does it work with the Allworx SIP?

The phone is standard SIP. We actually have the phone setup on our office Allworx system. I had a bit of trouble with initial setup, but Allworx support was able to do it in just a few minutes with relative ease. Best voice quality in a conference room phone we have had, even running with only Power Over Ethernet.

No it is a multiline S.I.P phone. You will be able to add multiple line SIP numbers, but not physical lines. Was disappointed with the phone because Google Voice Never worked, which was the main reason I bought it. Password error all the time. Ended up buying a multiline OBIHAI product.

I dont see why it wouldnt. It follows standard sip protocols, and is pretty dang easy to setup. Grandstream UCM is built on asterisk.

The device is definitely unlocked. It should support any service that can be supported using other sip clients. if you are able to connect to that service provider outside US (specially from the location you are planning to use it, say using a softphone, then this device should also work too. At the end of the day, it is a softphone embedded on to a chip).

Not sure I used it out of the box on a Mitel 5000 system. Though I had licenses to do so. I think its sip.

I got mine to work on Freedompop. Just don't get the triband spark model that one won't work. I actually changed mine from Freedompop to chitchat mobile. Call quality is much better if u need voice calls.

When it worked it only worked with Skype. It's called a Skype Phone. Of course, my first one quit and the new one doesn't work at all.My iPod Touch and iPad work with other VOIP services. That's what I'm using now.

That is a question that your phone service provider should have the answer too. Polycom phones are open SIP, but ShoreTel might have restrictions on what phones can be used with there systems.

Yes it should, depends on the provider though. You would need the SIP credentials, which you would put in through the phones web interface

No it is not compatible with Vonage. Vonage also uses SIP for their backbone but they do not publicize their SIP servers and also use some SIP extensions that are not available on this device.

It will not work with standard Skype. You would need the Skype Connect service to use the SIP features. I personally use it with another SIP service (CallCentric) that is inexpensive and gives me unlimited nationwide calling.

I am using it on an analog line, so can not answer your question exactly, but the product information states that it does support SIP as well:http://www.polycom.com/products-services/voice/conferencing-solutions/conferencing-phones/soundstation-duo.html(On the 'technical specifications' tab they have a link to supported SIP platforms.)The 'Duo' name is because it supports both analog and IP voice solutions. If you have not already, you may want to call VoIPCheap and ask them specifically if their service supports this phone directly (without any other hardware), or if it still requires a seperate SIP router. Wish I could help more.

No, Google Voice is not SIP Compliant, this device is only for SIP services

I would say if it can support a standard SIP phone, it will work. What I did is tried my Cisco Call Manager Express with a SIP softphone before purchase.

Hi i am not sure by what you mean unlocked but it is a SIP compatible phone. We have them connected to a Fortivoice FVC-100 telephone system and they work very well. If you have any more questions you may email me directly at mregan@regatronics.com
