Will it work on a Cisco IP Phone 303?

It is a smaller input jack than the ones meant for, say, an iTouch or iPad. Check the size with one of those devices; if the Cisco phone is larger hole--like the one on an iPad, then it will NOT work.

I would say NO. There are several headsets that are made for VoIP phones only and they are linked to the maker.. I travel between offices and had to get a set for the Avaya phone and one for the Cisco. I would look for supported models for your phone.

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

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". That is how it works on my phone. https://www.google.com/url?sa=i&rct;=j&q;=&esrc=s&source;=images&cd;=&cad;=rja&docid;=a3EaaDn0yY6AYM&tbnid;=kJEBZ3sTUoS5YM:&ved;=0CAUQjRw&url;=http%3A%2F%2Fwww.cisco.com%2Fen%2FUS%2Fdocs%2Fvoice_ip_comm%2Fcuipph%2F7960g_7940g%2Fsip%2Fenglish%2Fuser%2Fguide%2Fsipuinst.html&ei;=A7LZUoutKaqa2AWKvYGQAg&bvm;=bv.59568121,d.b2I&psig;=AFQjCNEP7MS1rn8TIfJwxdiwLCOdIrRpdw&ust;=1390084952882941 I'm not familiar with a Cisco 7490, but there is a 7940 Cisco Telephone.

The voip part will depend on the voip PBX and phones you use. For most it will be fine, but if you were to install an all Cisco pbx and phones then this would not do the auto config like a Cisco switch would. We use these as workgroup switches for our Asterix VOIP system of over 50 phones (we have many of these going back in to a 48 port stack.

Yes, but the Cisco software is not very good and Netgear R6300 performs faster...

No way to know w/o bringing the device up. Then you can download whatever Cisco has available. I think 1.3.5p is current

Yes, This P/N replaces 15330-20010. It's the one closest to the firewall. It cleared error codes 300,301,303,305 & 1349. One of my happier fixes. The other one causes even misfires and 1345, just for your info! Hope this helps.

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 :)

This is made for specific models of Cisco phones and is not universal, therefore the connection jack doesn't fit correctly on other models. On the Cisco website, you can find better specs. As for the mobile worker, it might be better to have him/her set the office or home office phone to forward all calls to a cell phone instead.

Hi Kartik, this will only work with an analog phone line. If you need an ip conference phone check out the konftel 300ip.

If the Avaya 9640G VOIP phone is IEEE 802.3af compliant then yes, this will work.

Yes. The phone I use at work that I connected this headset to is a Cisco IP 7965.

Yes this should work with all services providers, it's the VoIP system you're connecting it to that has to be compatible (most are).

Absolutely no. This is the same receiver that I have and it does not work. This is a skimpy little wire and I'd be surprised if it works on anything. Definitely step up and by the Cisco one.

As long as you have a valid IP address, it should work fine. I am not sure about your particular modem, and if it uses DHCP or not.

Yes it does. We are extremely pleased with this and it works on all phones and with our Cisco VOIP dektop plones as well.
