I'm not sure about specific phones. I have a basic AT&T phone. It appears that it would work/plug into any average phone.

I think it will work.Make sure the size of sim card and 'country unlock' Good luck!

If you have the right connections on your cable it should work fine. I used my first one on an Avaya phone for several years.

I don't think this will work with a Avaya system, but am not %100 sure about that.

Yes this will work on the LG Lucid 4G VS840 as it also uses a micro-sim card.

It ought to. I had mine work with AT&T; in the states, Vodcom in South Africa, and Chunghwa in Taiwan. I suppose you could ask your carrier before you buy just to be sure though.

We have an avaya system, and run them through it. External dialing and extension dialing work fine, but special features like voicemail and programmed buttons may not.

If it has Bluetooth it should work fine. The version of Android doesn't matter.

It should. Just make sure the SDHC for high speed is on it or it will crash your phone.

Yes, but your VOIP provider will have to support that in order for it to work. Most of them will.

Hi James, yes as long as the Avaya phone is corded and not cordless, this headset will work.

It has a USB port, so as long as you have the proper cable for your device that connects to a USB port, it should work.

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.

It should work with any phone or device that uses this type of connector, I say yes.

I am not sure about the product's compatibility with that device. However, the item did not function and it was returned since we were thoroughly disappointed with its performance.

I think it will all work on wp-120 ultra. If it does not work send it back.
