I am currently using an NEC networked phone. It works best with a multifunction business phone. I bought one of these hands free headsets for a family member, but they had to buy a more expensive phone to use it.

Possibly, depending on the Avaya system options you purchased. I am using this phone on an analog line (RJ11). If your system allows for an analog line, then it will work well.

At least ask a proper question, check your mobile model number and read description !!!!

No idea. Was only tried on an AT&T; phone. Is your phone specifically listed as one of the models in the Amazon description?

microSD, microSDHC up to 32 GB so yes it should work (if you want more details http://www.phonearena.com/phones/LG-A340_id6836 )

I think the compatability guide here will help you:http://telephones.att.com/product-support/compatibility-finder/0

I am not sure about the carrier compatibility in US as I am using the phone in India.However I also faced the same problem that my phone didnt detect the sim and the problem was resolved by getting the SIM TRAY changed.You may first use the sim on some other phone and if the sim works then in all probability the SIM tray may be faulty.

I had same problem. My charger was a 1029YA, but I could only find -ZB or -ZS. The compatibility list for both of these does not include the TGA470B. I spent hours on the web looking, and contacting Panasonic. There is no -YA out there...only solution is to buy the entire handset, just to get the miserable cheap plastic base part that failed....nice work Panasonic, why do you fail to support all of your products with replacement parts?

I don't know. We have a NEC system. We just had to plug the phone in and follow the set up instructions. We had no issues. You may want to contact a Avaya rep and ask if system has requirements for conference phones.

You need to call your phone provider and just give them the phone specifications and then they will tell if its compatible

After that lengthy answer, I just realized that it was for the wrong phone, as this is a model I returned.....I then purchased an AT&T; phone.....sorry for the confusion!

These phones utilize the SIP protocol. If 8x8 uses SIP, then it should work.

Make sure it says international unlocked. I am from Honduras and I have used the Lumia 920 and the 1020 here with no problems

Hello Meghan, This adapter only works with Cisco phones (but not ALL Cisco phones) -- what you need is our PH25-RJ9A adapter. It works with your Avaya phone. Link here: http://www.amazon.com/Headset-Buddy-Adapter-2-5mm-01-PH25-RJ9A/dp/B004FVDUAW Thank you, Long Tail Products Support
