SIP trunking is hot. Very hot. According to a survey of North American enterprises this year, one third of them use SIP trunking today and 42% of them plan to use it by 2014.  But you don’t want to get burned rolling it out to your organization without first doing a good amount of research.

The first major issue enterprise IT and network managers face is the fact that service providers offer various flavors (no pun intended) of SIP.  They don’t use consistent terminology, their pricing components never line up exactly, and they don’t have parallel service offerings. All this makes it very difficult to compare apples and oranges and a big challenge to make an intelligent decision about which provider’s solution is best for you.
