Session Initiation Protocol (SIP) Trunking is the use of voice over IP (VoIP) to facilitate the connection of a private branch exchange (PBX) to the Internet. SIP is the standard communications protocol providing a unifying voice and video solution across a data network that significantly improves communication.

SIP Trunking replaces the need for traditional analog, T1-based Public Switched Telephone Network (PSTN) connections. Termination is provided over your private or public internet connection through an SIP provider.

Allegiant Telecom’s telephony solutions enhance business continuity throughout your network. Efficiency markedly increases because there’s no need for a physical connection to a phone company with SIP Trunking. No hardware, wiring, or circuit boxes are necessary to maintain a connection to the PSTN. Condensing multiple phone lines into a single point of entry drastically reduces charges for incoming lines and the IT cost associated with their maintenance.

You’ll see reduced monthly phone bills, including charges for incoming phone lines, long distance charges and IT and maintenance fees. Not only are communication costs streamlined but also unused resources are reduced or even eliminated. Pay for the lines you need rather than being locked into more analog lines or T1s and PRIs that are only used occasionally.

If VoIP is already being used within your company’s PBX on the Local Area Network (LAN) to connect to IP phones, Through Allegiant Telecom, SIP Trunking also uses cloud VoIP to take advantage of shared lines, including your internet connection, which allows more flexibility in your network communications.

SIP Trunking is another flexible, secure and reliable communications solution backed by expert support and rock solid network. It’s what you can expect from the leader in telephony solutions for more than 40 years – Allegiant Technology.
