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.

The Polycom stands by itself it doesn't need another phone to work it is a phone just a different type.

It is compatible but not as simple as using the seeeduino brand gsm/gprs module. Try to buy that one instead. Works like a charm. Cheers.

Yes, it does appear to be compatible. Here is a link to the compatibility list on AT&T's website. The 86109 is on the 3rd page. http://cdn-media-att.vtp-media.com/media/p/document2/products/%7B581C04FF-DD51-4EEA-AFE4-A31691DFA8CE%7D/TL7800_compatibility_list.pdf

This does plug right into the jack where the handset is. I don't know about Nortel but my phone is a Meridian and it works really well.

Each specific series must be researched to see which are listed as compatible. Go to the basic phone set description. I would not know without checking.

I think it's only AT&T; compatible but I'm not sure. You should ask the seller. Have a blessed day!

I remember researching that and buying the phone because I was told it would be compatible. Unfortunately I couldn't tell you with certainty because I never unpackaged the phone. We installed a digital phone system in our office shortly after buying the phone which required specialized proprietary phones. I have been meaning to list it on the site for resale but have been putting it off. Let me know if you would like to make me an offer and I can sell you mine (stil unopened in its original packaging).

Shouldn't be any problem. The BB 9790 is a quad band phone and also works on the 1900 Mhz.

Look up this phone on Walmarts site, there is a box there to enter zip code, and it will tell you wether the unit is compatible. There are two versions of that phone and I have one and am in Ct. Awesome phone for what ya get though...I'm impressed. Including the lifetime triple mins.... Good luck...

Might be compatible. Its crap though. Reception no more than 3 feet and interference if you walk across the connection.

I'm sure its compatible, but you might want to go online and check the product brochure.

I'm pretty sure if its the same phone then it fits . It doesn't matter who your network provider is . As long as you got the right model for the case .

i plugged this into my office phone and it worked well. Then they changed the phone system which made it incompatible. I would start there, and look for compatible equipment. Its just to iffy.

It does not say it is compatible with that model#. It says in the product description which one this particular item is compatible with.

...if that model has a headset jack that is the same size as the handset wire connector, it should work. Mine works well on a Cisco IP Phone 7945.
