Does this phone work with the sip protocol, I'd like to use it with my asterisk IP PBX (Grandstream). Does anyone have a know if this can work?

We currently use it with an Asterisk based PBX. I'm not familiar with the Granstream PBX, but I'm sure it will work. However, I'm not a fan of that phone. We stopped using them. We use the 303 instead. It has a better speaker phone & seems more stable.

Not really sure about "unlocked" we add the phone to our Elastix IP PBX and works perfectly! SIP compatible.

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).

Hello, I purchased one of these and ended up with an identical problem. I returned it to the seller and bought the Phillips VOIP model and base which sadly are discontinued. As for this phone you're experiencing trouble with, the best thing to do is to purchase the base intended for it. If not, there are other products available on the market which include a camera in the handset, though they are more expensive. I hope this explanation helps a bit. Kind regards and God bless.

I have spent the better part of three days researching lines that will work with this. Very few phone vendors know what "analog" is. None guarantee it will work. Rumor has it that the Vonage Box VoIP Phone adaptor will work. I am willing to try it because it is the cheapest and fastest device to set up requiring an internet router, a Vonage box and a TTY, some phone cord. IP text relay is being eliminated by the FCC as of November 14, 2014. Those of us who do not hear or sign in ASL must get an alternative method of communication.

The way it is set up out of the box is that each handset is put on a different extension. Conferencing is something that is handled by your PBX server, so before you buy this you'll want to make sure that the service you're connecting to supports multiple users, and that there is a simple way to conference them together.

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.

6:30 pm 18Jan15Hi! there, JamesYes, this Grandstream is compatible with a Skype account set up. The process is very similar to using a PC/Laptop. The respective skype addresses are entered into the phone either manually or configured to 'auto-connect'. BTW. I have an extra unit still in the box that was purchased as a backup. I'll let it go for a fair amount. Take care. Kind Regards, Richard

Sorry, I do not have voip so I am unsure. I can say that it does work great with regular phone service.

Yes, it will work with it, the difference is that it saves cost, easy to manage, one point of support. This phone support both analog pots line and connecting to IP PBX and that is why it's called duo.Hope this helps

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.

The analog connection will work with any existing phone system that support analog phones. On the VoIP side which you're alluring to, the phone supports SIP registration for which all existing VoIP PBXes should support. I've not tested your specific configuration, though all indications are that it will work.

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.

The PAP2T-NA will not work with Vonage. The PAP2T-NA supports open protocols such as RTP and SIP where as Vonage uses a proprietary protocol. As for unlocked, this means the PAP2T-NA was never locked in to a particular customer or the adapter was unlocked for the secondary market. I use several with my asterisk server and have never had any issues. Sometimes the boxes do get warm so they need lots of ventilation. larry@databases4you.com

I don't know the answer to your question. The place where I work switched to a Jive cloud system and we now use Polycom phones. My IT Admin shipped the Grandstream phones to another location that is using a different phone system. I only had the Grandstream phone working for a few minutes before I put it back in the box and gave it to my IT guy.

Never tried that but I don't know why that wouldn't work.Keep in mind you have be configured to a SIP server first.
