Business telephony has never been easier. SIP trunks standardize IP-based business telephony. But what is a SIP trunk?
In this article, we explain what a SIP trunk is and how it works. We also outline the benefits of SIP trunking and the reasons why you should switch to our TKD SIP trunk.
What is a SIP trunk?
What is a SIP trunk? SIP stands for Session Initiation Protocol, a network protocol that allows you to manage communication sessions (usually phone calls). The term “trunk” refers to a bundle or group, as multiple phone numbers are grouped together under a single connection or SIP account. With a standard VoIP connection, each number has its own SIP account.
A SIP trunk can be thought of as a virtual channel that connects your phone system to your telecommunications provider. Signal and voice streams are transmitted over the Internet using Voice over IP (VoIP) technology. SIP trunks can be used in place of traditional ISDN lines or as a supplement to existing ISDN lines.
Unlike private VoIP connections, which are assigned only one phone number, SIP trunks allow for multiple phone numbers (known as number blocks). This means that the extensions or end devices of all employees are connected to the telephone network via a shared connection. A SIP trunk can also handle multiple calls simultaneously. The PBX manages the extension numbers and handles the routing of incoming and outgoing calls.
How does a SIP trunk work?
Like traditional VoIP telephony, telecommunications via a SIP trunk require a broadband connection through which voice packets are transmitted. With SIP trunking, you can group multiple phone numbers into a single number block that can be dialed directly from a single account. A central IP-based private branch exchange (PBX) registers and routes incoming calls to extensions.
Advantages of a SIP trunk
- Reduced monthly line charges: Using multiple lines and extensions can be very cost-effective.
- Falling call rates: The wide range of SIP trunk providers and the resulting competitive pressure have led to a significant drop in call rates.
- Better customer service: Allow your customers to contact you via additional local and international phone numbers. A corresponding number is added to the SIP trunk and assigned to the IP phone system. A local phone number offers lower call rates for your customers.
