What is SIP trunking?
SIP (Session Initiation Protocol) trunking is a method of delivering telephone services via data networks instead of traditional fixed phone lines. It enables users to place and receive calls via the Internet Protocol (IP) without entirely replacing their existing PBX system.
Similar to VoIP, SIP trunking employs IP technology for the transmission of voice calls. However, SIP trunks also support video, messaging, and fax communications.
SIP trunks merge the latest advancements in telecommunications technology with the existing, compatible infrastructure of legacy PBX systems.
SIP trunking provides a solution that is future-ready, scalable, feature-packed, dependable, and economical.
SIP trunking services are the perfect solution for businesses looking to upgrade their legacy telecommunications infrastructure and streamline their operational workflows.

SIP trunking service requirements
Before adopting SIP trunking for your enterprise, you must be aware of the equipment you’ll need to ensure flawless and high-calibre communication.
Key among these is compatible hardware, notably a PBX system that supports IP-based services. Equally important is a dependable and fast internet connection for the best possible performance. Dive into the details of these crucial requirements and get in touch to discover more about our SIP trunk solutions.
Hardware for SIP trunking
A PBX (Private Branch Exchange) system drives SIP trunking and is essential for interfacing with IP-based services. Modern IP-PBX systems offer enhanced compatibility for SIP trunking, while traditional PBX models can be made compatible through the use of VoIP (Voice over Internet Protocol) gateways.
Stable internet connection
A reliable, fast (fibre or LTE) internet connection is crucial for high-quality voice communication. It’s important that you have ample internet bandwidth to handle concurrent phone calls alongside your usual business data traffic.
Frequently asked questions about SIP trunks and SIP trunking providers
Is SIP trunk a VoIP Technology?
SIP trunking is a component of VoIP technology that facilitates voice communications over the Internet. The relationship between SIP and VoIP is that SIP trunks enable VoIP services by connecting a PBX to the internet, thereby supporting voice, video, and other forms of digital communication, distinguishing SIP as a specific protocol within the broader VoIP framework.
How does SIP trunking work?
A SIP (Session Initiation Protocol) trunk serves as a digital bridge, enabling voice communication over the internet by converting voice signals into digital packets that travel over IP networks.
Our SIP trunking services integrate smoothly with your existing PBX system, delivering a reliable and cost-efficient method to improve your business communication. Contact us today to transition to this advanced telephony solution.
How to configure a SIP trunk?
Configuration steps vary depending on your PBX system and the chosen SIP trunk provider. Popular platforms such as Cisco CallManager and Asterisk have distinct protocols for SIP trunk setup.
At United Telecoms, our expert technical team offers extensive assistance to navigate the configuration process, ensuring seamless integration with your business communication systems. Reach out to speak with a professional today.
How many concurrent calls can a SIP trunk handle?
The number of concurrent calls a SIP trunk can support is determined by the bandwidth you have and any restrictions imposed by your SIP trunk provider. Understanding these elements is crucial to gauge your system’s ability to handle simultaneous calls.
Our SIP trunking services are adaptable and designed to accommodate your precise call volume demands. We also provide a clear evaluation to ensure peak performance. Contact us to explore your options.
How to check the SIP trunk status on a router?
To verify the status of a SIP trunk on a router, you can use specific command-line interface (CLI) commands. Commonly, the show sip-ua status and show sip-ua registrations commands are used to view the trunk’s operational status and registration details.
For detailed guidance and support with these commands, our team at United Telecoms is ready to assist. Contact us for expert help and ensure your SIP trunk is functioning optimally.
What is the difference between a SIP trunk and a SIP gateway?
A SIP trunk establishes a digital link between your PBX and the internet, facilitating VoIP communication. In contrast, a SIP gateway is a device that not only connects your system to the internet like a SIP trunk but also bridges it to conventional analogue phone lines (PSTN network).
Whether to choose a SIP trunk or a SIP gateway depends on your specific communication needs. United Telecoms is ready to assist you in selecting the most suitable option for your business. Contact us today for tailored advice.
What is a SIP trunk channel?
A SIP trunk channel acts as an individual pathway for a voice call. The total channels available dictate how many simultaneous calls your system is capable of managing.
Our services include customisable SIP trunk options that can be adapted to your channel requirements, ensuring your system can scale alongside your business’s expansion. Reach out to us now for a SIP trunking solution tailored to your needs.
What’s the difference between a SIP trunk and a SIP session?
The difference between a SIP trunk and a SIP session lies in their roles and functionality. A SIP trunk is a virtual line that enables multiple voice calls or sessions over a single network connection, primarily used for linking PBX systems to the internet. A SIP session, on the other hand, refers to a single call or communication instance established using the SIP protocol, facilitating real-time voice, video, or messaging sessions.
