The Cisco SPA303 is compatible with many business VoIP subscriptions, and is perfect for small businesses. The phone specifically showed up as a reveler in my BYOD party, hosted by Nextiva. Cisco is a trusted name in manufacturing, and this IP phone is no exception to that reputation. Not only is the Cisco SPA303 a great budget phone, it's also compact and very capable – working incredibly well with my Nextiva service. Setting the device up was very easy, as I did so in less than five minutes via the provider's online portal. Check out the seamless effort in unboxing and setup of the Cisco SPA303 in the video below.
