The Cisco SPA301 VoIP IP Phone is an affordable generation of SIP based (Session Initiation Protocol) IP Phone that is marketed towards the small business and home office user. However, I think this could be a good starter Phone for anyone wanting to give VoIP a try.
This is a basic 1-Line IP Phone and is a great way to get started with BYOD and DIY VoIP. The phone is an all-in-one VoIP Phone that doesn't require any other adapters. Some people may find it a good outbound long distance calling phone due to it's lack of a call display.
In this Quick Guide, it is my intention to walk you through the basics of how to quickly (relatively speaking) configure your newly acquired SPA301 IP Phone directly with CallCentric, one of my preferred BYOD and DIY VoIP service providers.
To achieve this goal of quick and easy configuration, I will begin with the SPA301 as configured with it's factory default values as a starting point. Then, I will only point out the essential settings that "must be edited" in order to connect and achieve reliable service registration with CallCentric.
