Purchased this cord for my Polycom VVX 500 phones that are set up with Ring Central for my business. One of the cords had a short and we needed one asap. We opted into order this for same day delivery and was delivered as promised and works perfect. The pictures that are already on Amazon show pretty much what it looks like, I tried a Walmart cord and had no luck. Amazon is absolutely a life saver!

Pack very nicely got here on time and worked!

Perfect fit for a Polycom phone that I bought on clearance, and couldn't find another power supply that would!!

This adapter was necessary in order for us to utilize a Polycom VX300 phone that was connected to a network that did not have a POE connection which meant there was no power going to the phone. We plugged in the adapter to the phone and AC power, connected the phone to the network and computer and the phone lit up and worked. We had originally ordered an adapter from another Amazon retailer but delivery was going to take over a week, FOMI had it to us in 2 days.

Cord was shorter than I was hoping for, but worked like a charm on my VVX311's! Thank you

So far no issues with these. We will be using with remote workers later this year in their home offices. Most employees are not going to have POE network, or any wired network, available in their home offices, so these will allow them to use a regular desk phone at home instead of their mobile phone or PC.

This is a power adapter for a phone that I discovered from my IT department wouldn't work with our business network. I'm sure it's fine, I just couldn't make use of it.

don't know why this was recommended with my POE injector, but it does not comply with 802.3af and will probably burn out your device if you use it.

Works great with my Astra 6755i phone. I was having a difficult time finding a cord for this phone until I came across this product.

Work as described. Fast delivery.

Worked as described. Quick delivery.

So not buy this for VVX450 as Amazon suggests for it. It is not compatible.
