SIP Trunking: Efficient Voice Communications

SIP Trunking: Efficient Voice Communications

Atlantech Online offers Hosted PBX service which is very popular with our customers. We also deliver PRI and analog lines to customers that have a legacy PBX. But, Atlantech Online can also deliver SIP Trunks to those that already have their own VoIP PBX. SIP Trunking is an innovative communication method that uses an Internet connection instead of a conventional phone line. With this technology, you can make and receive calls over the Internet to anyone in the world who has a phone number.

What is a SIP Trunk?

SIP Trunking replaces the traditional method of the public switched telephone network (PSTN) or PRIs (Primary Rate Interface) and instead uses a specific packet switched network to send voice traffic to a destination. The ‘SIP’ in SIP Trunking stands for Session Initiation Protocol, which is the standard communications protocol for voice and video in a Unified Communications (UC) solution across a data network. SIP can be used to send and receive local and long-distance phone calls, text messages, emails, browse the internet, and conduct video chats.

A “trunk” is a line or link that carries signals and connects nodes in a communications system to transport data across locations. Put it all together, and you get SIP Trunking – the method of sending voice and other communications over the internet through an IP-enabled private branch exchange (PBX).

Benefits of SIP Trunking

The benefits of using SIP Trunking are numerous. First, it enables one centralized network for voice and data services, which means no physical infrastructure, maintenance, or hardware costs or headaches. Second, connecting directly to the Internet telephony service provider of your choice (such as Atlantech Online) removes subscription fees and allows for flexibility in scaling your bandwidth needs. Third, SIP Trunking makes every call a local call over the Internet, avoiding typical toll calling costs of calls over the legacy telephone network. Additionally, it is flexible and easily scalable, with new channels that can be added and activated quickly. We have one local government customer who adds more capacity over their SIP trunks during weather events such as snowstorms and tropical storms.
