Three Things You Really, REALLY Need to Know Before Tackling SIP Trunking
In the late 90’s it was Frame Relay; five years ago it was MPLS. Now SIP trunking is all the rage in corporate telecom circles. There are two good reasons for that.
First, it saves large users a lot of money in an area (voice, and particularly local voice) where savings have been hard to get in recent years. Second, the incumbent local exchange carriers are the carriers that every enterprise loves to hate (high rates, lousy terms, arrogant attitude) and SIP trunking gives you away (finally) to show them the door.
