SIP Trunking

In the sphere of telecommunications, Typex introduces SIP Trunking, a cost-effective and flexible alternative to ISDN for voice calls. SIP Trunking, a more flexible, less expensive, and more resilient service, is rapidly replacing ISDN for inbound and outbound voice calls.

The Future of Voice Communications

SIP Trunking connects your site’s PBX directly into the network via an internet connection to carry and terminate your calls across the public telephone network. With ISDN set to phase out in 2025, it’s an ideal time to explore the benefits of switching to SIP Trunking.

Cost Saving

SIP Trunking can save up to 50% on line rentals and 25% or more on call costs.

Business Continuity

SIP Trunks inherently support disaster recovery and business continuity, enabling quick and easy rerouting of calls to an alternative location.


SIP Trunks are ideal for businesses undergoing changes such as moving, upsizing, or downsizing, and who wish to retain their existing numbers.

What is SIP Trunking

SIP Trunking, or Session Initiation Protocol Trunking, is a method of delivering voice and other unified communications services over the internet. It works with a PBX (Private Branch Exchange) system.

When a user makes a call, the voice data is converted into data packets and transmitted over the internet via a SIP Trunk. The SIP protocol is used to set up and manage the call, handling the routing of the call to the correct destination and then terminating the call when it’s finished.

New Phone System?

One of the key advantages of SIP Trunking is its compatibility. Most modern phone systems can communicate directly with SIP Trunking services. This means that businesses can take advantage of the benefits of SIP Trunking, such as cost savings, increased flexibility, and improved scalability, without needing to replace their existing phone system.

Even if your phone system isn’t compatible with SIP Trunking, there’s no cause for concern. We can configure your SIP Trunk to emulate an ISDN line. This means that to your phone system, the SIP Trunk appears just like a traditional ISDN line. This allows you to enjoy the benefits of SIP Trunking without the need for a major overhaul of your existing telephony infrastructure.

In essence, SIP Trunking provides a flexible, scalable, and cost-effective solution for businesses looking to optimize their communication systems. Whether your phone system is already compatible with SIP Trunking or requires an ISDN interface, we can provide a solution that meets your needs and drives your business forward.
