Cisco Systems Small Business Pro Phone Adapter with Router

I received this item as a package from [...] about 4 months ago, they have an unbelievable package and the lowest price on the internet (200/year!) - I had to try it. Installation on my network was easy even with the complexity of my network (multiple hardware routers and firewalls). For most users it simply replaces your existing firewall, plug it into your cable/dsl connection, plug your computer into it, after about 30 seconds to a minute the SPA-2102 will sync with the VoIP provider and your set to go. Voice quality is so good i thought the calls coming in were on the old phone line! 5 Stars by me, goodbye ATT!!!! :D

Once you finish with the complex set up process which includes connecting through a network cable with your computer and changing a whole lot of different values (needs expert guidance on what to change) the cisco VoIP is great. You have to connect the AC power, phone plug and network cable and you are ready to go.
I'm in a place where the fastest internet connection is awfully slow (512Kb), however the sound quality is great. One out of ten calls has delayed sound or distorsion, for the rest of the time you feel you are calling to your neighbor.
Another great attribute is that is very small and light; you can pack it in your bag and take it anywhere. AC adapter is good for 120V to 240V, another flexibility to take it to different countries with different voltages (you may need an adapter for different connections shapes).
