What is a SIP trunk?

SIP trunks provide voice connectivity to the telephone network by only using an internet connection. Based on the Session Initiation Protocol, SIP trunks handle a high volume of inbound or outbound calls using a Private Branch Exchange (PBX) server.

A SIP trunk is the virtual version of an analog phone line. Using SIP trunks, a SIP provider can connect one, two, or twenty channels to your PBX, allowing you to make local, long distance, and international calls over the Internet. If you have an on-premises PBX in your office, a SIP trunk provider can connect to you and allow you to make outbound calls on your existing system, without restrictions on the number of concurrent calls.


Why use SIP trunking?

Modern SIP trunks provide superior call quality compared to their legacy counterparts and callers will experience crystal clear audio.

Utilizing SIP trunks will also eliminate the need for expensive legacy equipment and maintenance costs, allowing you to invest elsewhere in your business. Legacy equipment can also be a single point of failure, whereas SIP trunks have built-in redundancy and failover.

With SIP, your call charges will be significantly cheaper, especially if you opt for our unlimited call plan. That’s an instant return on investment.

The scalability and versatility of SIP will allow your business to adapt to changes in growth with ease and speed – react in minutes, not months.
