Most small businesses are happy with normal phone lines and a receptionist or autoattendant to route calls. But some small businesses want numbers which ring directly to certain extensions, best known as a DID.
Traditionally to have DIDs you need a T1 or PRI plus a compatible phone system. The issue here is cost, a T1/PRI is in the $500/month ballpark and T1/PRI capable phone systems cost significantly more than phone systems using phone lines or VoIP - for example a T1 capable Allworx 24x is nearly $4000.
SIP trunking is the other way you can accomplish DIDs and instead of paying for an expensive T1/PRI, SIP trunking packages start at just $30/month. Admittedly you still need more bandwidth, I like to toss in a dedicated DSL for VoIP which runs another ~$60/month. SIP trunking phone systems cost less than T1 phone systems, for example an Allworx 6x with VoIP is $2250, or SIP trunking Talkswitch 248vs is just $1095.
SIP Trunking (VoIP) isn’t always the right answer and doesn’t always cut costs, but depending on the situation it can bring DIDs to small business for an irresistible deal.
