Delivering Voice via the Internet

SIP (session initiation protocol) delivers voice through digital network technology rather than telephone technology, using packets of data over Internet connections instead of traditional copper wiring. SIP phone service is used just like analog telephone service, except that SIP trunks are virtual and, therefore, involve no hardware installation or related costs. New SIP solutions integrate the latest Voice over Internet Protocol (VoIP) technology to deliver improved clarity of voice and reliable connectivity.

Integrating voice and data onto one circuit and utilizing dynamic allocation allow you to use your bandwidth to its fullest capacity, regardless of the time of day or the number of phone lines in use. When your company grows, you can easily expand the number of call paths by utilizing pre-existing additional bandwidth without the cost of additional modular hardware for premise-based phone systems.


With Access One, you get a solution customized to your business and infrastructure. We provide SIP trunking over your current Internet services, or our engineers will work with your private branch exchange vendor to configure, test and acceptance test before porting and production use.

The result is a SIP VoIP solution that delivers the best of both worlds: the reliability of SIP and the on-demand communication of VoIP. Our SIP trunk services are designed to deliver reliability and scalability — providing peace of mind for users and long-term benefits for business strategy.
