Power Supply for Cisco Linksys SPA IP Phones (PA100-NA) SPA300, 500, 900 Series-5V/2A

I bought this to use with a Cisco SPA 525G VOIP. It works perfectly. I think you can use a network cable if you'd rather, but my router is too far away from the phone for that to be feasible. This power supply worked great.After getting power, the phone is wireless. What I mean by that is that the phone connected to the wifi network. That took some doing, but my VOIP company basically walked me through the process without any pain.All in all, if you're needing a power supply for you phone, this one works perfect. No complaints.

The power supply that was sent with my phone never stayed in place. After two years of fighting I decided to order this replacement that works perfectly.

Since the CISCO SPA 525G2 phone did NOT come with a power supply, one had to order it separately. This model worked perfectly with the phone.

purchased as a backup to a Cisco Phone

The power supply is not configured as represented in the photograph in the Amazon listing. The receptacle is configured horizontally not vertically. The horizontal configuration blocks several outlets on my surge suppressor.If I wanted the horizontal configuration I could’ve purchased it cheaper from other Amazon sellers.

Arrived fast and is good quality

While this worked fine for powering my Cisco phone, it caused severe interference to nearby radios. I am going to need to purchase ferrite choke filters; they should have been included with the adapter in the first place! There is no way this adapter is compliant with FCC emission limits.

Product worked as stated and arrived when they said it would.
