This paper looks at the current state of Voice over IP (VoIP) from a technology manager’s perspective. Specific attention is paid to the small and medium sized business which have up until recently been under represented in the VoIP market. In this paper, both the positive and negative effects of VoIP implementations are considered to help the SMB manager make an educated decision about the appropriateness of VoIP in their own environment.
I finished this paper in November of 2005. The VoIP landscape has changed somewhat in that time but the underlying issues there were true in 2005 still hold true today (August 2007).
This article should help to quickly bring someone new to VoIP up to speed and point that person in the right direction for learning more about VoIP.
