What is SIP Trunking?
SIP (session initiation protocol) trunking is an innovative form of telephony that connects your company’s phones to the public PSTN telephone network via internet-based data transfer and VoIP (voice over internet protocol), rather than through the traditional phone lines.
With SIP Trunking this means your phone services are no longer tied to any local exchange, meaning you can choose phone numbers without being linked to any specific region, as well as avoiding conventional calling charges. Data-based calls also offer a better sound quality, easier call recording and more seamless integration alongside systems like Microsoft Teams.
SIP trunks are a direct successor to older ISDN lines, with an increasing number of businesses shifting from ISDN to SIP trunk-based telephony in recent years.

SIP Trunk Solution FAQs
What’s the difference between SIP and VoIP?
SIP (Session Initiation Protocol) and VoIP (Voice over Internet Protocol) are related and are often used together in modern communication systems, but they both serve unique purposes. Here are the key differences between SIP and VoIP
VoIP (Voice over Internet Protocol):
Broad technology for transmitting voice, video, and communication over the internet.
Encompasses a range of protocols, including SIP.
Used for various communication services like voice calls, video conferencing, and messaging.
Examples: Skype, WhatsApp.
SIP (Session Initiation Protocol):
Specific signalling protocol for initiating, controlling, and terminating communication sessions in IP networks.
A subset of VoIP, focusing on session setup and control.
Primarily used for voice calls, video conferencing, and real-time communication.
Example: Used to establish and control calls, while VoIP handles actual data transmission.
Is there a limit on how many phone numbers I can have?
There is no limit on the number of phone lines with SIP trunks, making it highly scalable for businesses of all sizes.
How many concurrent calls can a sip trunk handle
The number of concurrent calls a SIP trunk can handle depends on several factors, including the capacity of the SIP trunk, your network infrastructure, and your service provider’s offerings. Contact our expert SIP Trunk team for more information on your SIP requirements.
Why do i need a SIP trunk
SIP trunks are a cost-effective alternative to traditional phone lines, offering substantial savings on long-distance and international calls. They provide scalability, allowing you to easily adjust the number of concurrent calls to match your business’s growing communication needs.
SIP Trunks promote business continuity with features like disaster recovery, ensuring your operations remain accessible even during network disruptions. We help modern businesses with streamline communication, reducing costs, and improving overall efficiency.
How do SIP Trunks Work
SIP trunks, or Session Initiation Protocol trunks are the backbone of modern business communication systems by facilitating VoIP and multimedia services over the internet. When a call is initiated, SIP trunks create a virtual “session” and use SIP signalling to establish a connection between your caller and you.
This signalling involves the exchange of SIP messages, like requests and responses, to initiate, maintain, and terminate the session. SIP also handles multimedia session descriptions and parameter negotiations during setup, such as choosing codecs and encryption. Throughout the call, SIP remains active, controlling features like call forwarding and monitoring the session.
As the call concludes, SIP signalling is used to gracefully terminate the session, ensuring that resources are freed up for future calls. Call Detail Records (CDRs) are often kept for billing and analysing performance of networks as you develop your business you may need to upgrade in the future.
