SIP Trunking

Home > Sip Trunking

Why Choose SIP?

SIP saves organizations money.  Traditional phone networks use copper wires to communicate with your in-house PBX. With SIP trunking, there is no need for traditional copper lines from the incumbent telco. SIP trunking uses Voice over Internet Protocol (VoIP) to create a virtual phone line or “trunk” to send voice traffic to your phone system. This allows you to reduce telecom expenses and gives you a much more flexible and expandable means of communicating.

What's The Difference Between SIP and VoIP (Voice over Internet Protocol)?

Although SIP and VoIP are often used interchangeably, they are not the same thing.  VoIP stands for Voice Over Internet Protocol.  It is a broad term that covers any phone calls made over the Internet. It includes a group of protocol technologies of which SIP is an example.  SIP is one of the specific protocols that enable VoIP.
