Do you know if this is compatible with the Avaya 4621 IP phone?

I am 99% sure it will work. I looked up the Avaya 4621 IP phone and it appears that the headset plug in is the same as on the headset. It is also good quality. I have had this product for over two years with no complaints.

Absolutely works with the Cisco soft phone. Download the Jabra PC Suite, indicate that you use either (or both) the Cisco and Avaya soft phones and you are good to go. I've tried a lot of different headsets but this is by far the best I've found.

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.

Good Morning, Rick. I now have an answer. ...apologize for taking so long. I successfully used it on each of the Cisco VoIP phones I tested. The models were: 7962 and 6941. These numbers are on both sides of the 7941, and if the 7941 has the hand set button, I have the greatest confidence it will work just the same. I plugged it in, and moved the dip switch to position "2", and it worked clear as a bell. Let me know if this helps. There is a receptacle on the Cisco phones mentioned -- for this plug; NO amplifier is needed.

Yes they do. Here's a list I found on the web of providers they work with: http://www.whichvoip.com/voip-phone/ip-phone-price.htm Usually just need to download a configuration script so they work with the provider.

You can test your connection at http://www.phonepower.com/speedtest and the site will let you know if your connection will support VOIP.

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.

I am not sure it is compatible. I had a similar problem when I purchased an add-on phone for my system and the phone did not work. To be safe I would buy the DCX291. Even if it is an older model, newer is not necessarily better and the 291 is specifically designed for your system.

I was wondering the same thing. This model is also sold on the Skype website, so I think it's a safe bet that it's compatible.

I use a different model of Avaya phone. If it has the RJ (phone) type connection, not the stereo mini, it should work. We really like ours. I have 7 in use now.

the device has an analog phone connector. If you had something that would convert that to an IP phone then it probably would work.

It should be fine. FreePBX is an Asterisk based IP platform I believe, and as such talks standard SIP. The Polycom Soundstation IP5000 is also a fully SIP capable phone, so it will work just fine. Only a few proprietary phone systems extend SIP in such a way that third party phones may not work (Mitel leaps to mind).Rubin

As Far as I know it will but not for sure. Its supports repeater bridge mode and WPA2 enterprise encryptions, don't know if PEAP mode works with it though.

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.

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