Will it work with Cisco 7962 ip phone?

It will work perfectly with that phone. In fact, that was the first model phone I used it on. I do recommend spending the extra to get the 'handset lifter'. It will make you truly mobile in the office because you will be able to answer without touching anything on the desk set, just the button on your ear!

It works with land lines and VOIP lines, I have it working with Vonage VOIP so I think it will work with Magic Jack which is VOIP based also.

Yes it will. I have a second desktop in my bedroom and I used the Cisco for the same purpose and it works fine.

This is an IP phone designed to connect to a SIP phone system. It won't work with an analog phone line, nor will it connect as a PC peripheral. I wouldn't recommend buying it unless you are very familiar with the details of how your phone system works, or you validate with your IT staff.

NO. This is an IP Phone which can be connected by a LAN jack (same like connecting the computer to your router / switch). It is the bigger jack called "RJ45".Since you are asking this, I assume you need to know the rest of the information, in order to use it, it can not get a dial tone from the normal wall plug. IP Phones need an "electronic" source for dial tones like PBX or VOIP service provider which can be easily found online.So, get a VOIP account, register it on this phone, connect the phone to your router, and enjoy the cisco quality :)

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.

PS....I use it on a Cisco phone and it works beautifully. Voice part and ear parts! I absolutely LOVE this headset!!!

I'm not familiar with a Cisco 7490, but there is a 7940 Cisco Telephone. The phone you have may be similar to the picture shown at this cisco URL (be sure to copy the whole URL or just Google "picture of rear of Cisco 7940".

No. This a Cisco phone appliance. Sorry. It very well with a network Cisco office phone.Russell Jones

It should. the C5502 model supports HSPA+ and recognizes 5 frequencies for 3/4G internet. I'm on ATT and it works great.

it will as long as it is a regular phone and not one that is on a IP system like Cisco... because then the cord will connect, but won't work.

Can't say for sure, but based on the description it doesn't support the Polycom IP. I haven't got a chance to official test it on a Polycom IP phone.

If you are asking if you can use the 7942G as a standalone network IP phone, the answer is no. It is a Cisco proprietary phone that uses the Skinny Client Control Protocol (SCCP) for terminal control by a Cisco phone Switch.

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

Unfortunately, no. You'll need to order the cord appropriate to your phone. For example, I have a Cisco 7970G desk phone so I had to order the APC41 to get the correct connections.

Only if the answering phone has Bluetooth capabilities. So, if your IP phone has the ability to resend the functions of talk and listen and directory dialing of stored numbers, then yes it can.
