SIP Trunking
Choose SIP trunking for its scalability, breadth of features,
and lower cost structure.


SIP Trunking

Session Initiated Protocol(SIP) trunking uses an IP(Internet, MPLS, etc.) connection to create a call path between 2 parties. Trunks are purchased according to the number of anticipated simultaneous calls in an enterprise. If you find you need more call capacity, you can simply add trunks as needed. SimpleSIP Trunking is your conduit to a converged IP world.

SIP Trunking Benefits:

  • Built-in Disaster Recovery – You’ll never miss a call with SIP Trunking’s failover system. If your trunk is damaged, your call can automatically be re-directed to your cell phone or alternate landline.
  • Infinite Scalability – Don’t be constrained to the limits of analog of lines or PRIs. The only constraint on SIP trunking is the amount of internet bandwidth upon which to provision SIP trunks onto.
  • Fast Deployment – Simply contact the carrier through an 800 number or a portal and increase the number of trunks on the fly.
  • Web-Based Provisioning – Most carriers have a web based portal that allows you to increase SIP trunks on an as needed basis.
  • Layered On Features – Integrate voice, email, fax, and advanced call routing features on top of SIP trunking to give your employees a seamless communications experience.
