Is this product compatible with Cisco phones? Specifically the SPA504G?

These Cisco SFP's can work with other hardware manufactures besides Cisco. However, you must check with the hardware manufacture to verify they'll work and are supported.

Although I am not sure, I believe it is. I know that it works with my iPad and iPods. I only installed the Cisco connect software on my PC.

I would say yes, as the one I bought was used with a Cisco 7960 and worked well. I was given a Polycom phone recently and replaced the section of cable below the connector at mid-cable and the same headphones that worked with Cisco 7960 works with a Polycom Soundpoint IP550.

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.

It depends on how it will be hosted... if you plan on having an onsite PBX system from Cisco (UC500, Business Edition 6000, etc.) you shouldn't have a problem creating shared lines. However if you choose to go with a hosted pbx system (Nextiva, Jive, RingCentral,) these phones may not work with shared lines. It would be best to contact the VOIP provider you choose, unless you go with a Cisco On-Site PBX System. I am not sure of any other On-Site PBX System I have only used Cisco products, and have tried a few hosted pbx providers.

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

We use our Cisco SPA525G on a VOIP system through Vocalocity and have not had any issues. Vonage recently merged Vocalocity (our service provider) and we have had no interruption in service. Vonage and Vocalocity operate the same type of system so it should not be a problem.

Hi There. Yes, this headset will definitely work with that Cisco phone system. Please let me know if you have any questions.

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.

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.

Probably ought to contact Cisco to ask the question as mine is on a PC and works perfectly. Sorry that I can't give you a positive response.

My admin assistant was able to get the incoming calls to ring on my cell and cisco phone simultaneously, in series or individually. The phone was very programmable. You can log into your phone system and change the settings any time. We only used it with ring central so I don't know if other companies have the same capabilities.

Yes, it's SIP compatible. I have one that's been used with various SIP service providers over the years. If it's new then in will surely be "unlocked." The only time these things get "locked down" is when provisioned by a service provider to then adds an admin password to protect the provisioning settings.

the Cisco 7841G requires no adapter - it is 48v 4 watts per phone - so this injector is the right solution for 8 phones

If the phone has a connector for an external headset (not just the handset connection) then it should be able to switch over to the headset for taking or receiving calls. It does have a handset output jack, so it can be daisy-chained with a normal handset (which would then have to be taken off-hook to init or answer a call). As for VoIP compatibility, this may help: https://supportforums.cisco.com/docs/DOC-9926 "Headset Compatibility for SPA303, SPA5xxG and SPA9xx Phones".

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".
