San Francisco Bay Area SIP Trunking

What is SIP Trunking?

Are you still using old-fashioned analog lines for your business? Did you know that the monthly cost for analog phone service has gone up by 50% over the past two years?


There's a reason for this. AT&T and the other big phone companies don't want to be in the analog phone business anyone. It's old, inefficient and costly to maintain. So they're raising prices to force their customers out. Don't let the big phone companies take your money! 


A SIP (Session Initiated Protocol) Trunk provides the same service youget from a traditional analog phone line or a channel (trunk) on a PRI. The difference is, instead of being a physical wire, a SIP Trunk is a “virtual” phone line which is provided by a SIP trunk provider. It uses your data circuit (T1, Cable modem, DSL, Ethernet over Copper, Fiber, etc.) to connect your phone system to the Internet.


SIP Trunking is Better Than PRI

There isn't much debate about which phone delivery system provides better features and reliability going into the future. SIP Trunking is widely heralded as a better option for a variety of reasons.   

  • Traditional PRI circuits have 23 voice channels. SIP trunking comes in increments of one channel. Pay only for what you need. 
  • Most SIP trunking implementations do away with traditional line cards. This lowers costs and eliminates future hardware failures.
  • If your PBX fails, you have a major power outage or building damage, or your connection to the Central Office goes down, your SIP trunks will still work. You can simply re-route calls to any telephone number in the world.
