Does it work on the Cisco 7942?

Yes, but they are not very good quality sounding. It sounds like you are in a tunnel, and the wires break easily so it breaks up frequently. I would not purchase these again.

It does work with that the handset, however, I have had a durability issue with them.

I dont know if it will work with that model, but it works great with my Cisco IP phone.

I use it with a CISCO 303 and that's all I've used it with. I suspect it's compatible with most if not all brands

I have a TG862 Arris from Commiecast. I could not get it to work...but it did work well, sometimes, with the Belkin N600 router I have. I say sometimes because the connection kept getting lost.

James, I don't know if it will work on those routers for sure. But It does fix to the DWP611 compact version, and it works great. I would recommend the guide if it does fit. I would imagine they all have the same configuration for the screw holes to attach the guide. Maybe someone else might have the same router as you that could tell you for sure. Good luck.

It worked on my Coby 8042; I just plugged it into the usb port and the Coby recognized it and everything worked fine; it still is working with any problems.

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.

Hi,My best guess it should work since it replicates a lan port from two different points. I hope this helpsD

Yes, these adapters definitely work with 7941. There are some issues with 89xx-series phones, however 79xx (xx40 and up) work perfectly.

Tim said a google search ought to reveal the path. I think you are looking for 7.4.1.37 but sourcing it may not be the easiest thing. Cisco is fairly tight with their firmware.

It should since it works with my Arris modem just fine. Someone came and installed the modem when I got Charter Internet.

I don't know about specific models but this device should be agnostic. I've tested it with Cisco/Linksys and Meraki products--two completely different products and it works. So as long as the device is using industry standard protocols, it should be fine.

Not sure. I have it working in a Cisco 7962. so maybe.does not work with 502 or 504.

Yes, I think so. This device comes with the latest firmware. I tried getting a newer firmware version as soon as I purchased the device, but none was available on cisco website.

Nope, but on the off chance it doesn't work with your cisco phone, let them know. Their customer service is top notch!

Not from what I remember about how Vonage works. If you have a SIP account with Vonage you might be able to get it to work, however you will probably be happier looking for something else that is more likely compatible. FYI, I use my 7940 with an Asterisk server.
