What is SIP Trunking?
SIP Trunking replaces traditional phone lines with internet-based connections, allowing your existing PBX system to make and receive calls over the internet at a fraction of the cost.
How SIP Trunking Works
SIP (Session Initiation Protocol) Trunking creates a virtual connection between your on-premises PBX system and the Public Switched Telephone Network (PSTN) through your internet connection, eliminating the need for traditional phone lines.
Cost Savings & Flexibility
By routing calls over the internet rather than traditional phone lines, businesses can reduce their telecommunications costs by 30-60% while gaining the flexibility to scale up or down instantly based on demand.
Perfect for Existing PBX Systems
Unlike Cloud PBX solutions, SIP Trunking allows you to keep your existing PBX investment while still gaining the benefits of VoIP technology, making it ideal for businesses with newer phone systems.

Frequently Asked Questions
Get answers to common questions about our SIP Trunking services
What is the difference between SIP Trunking and a hosted PBX?
SIP Trunking connects your existing on-premises PBX system to the internet for making and receiving calls, while hosted PBX replaces your entire phone system with a cloud-based solution. SIP Trunking is ideal if you want to keep your current PBX investment and just upgrade your phone lines.
Will SIP Trunking work with my existing PBX system?
Most modern PBX systems support SIP Trunking, including Avaya, Cisco, Mitel, ShoreTel, and many others. We provide compatibility testing and configuration assistance to ensure seamless integration with your existing equipment.
How much bandwidth do I need for SIP Trunking?
Each concurrent call requires approximately 100 Kbps of bandwidth (both upload and download). For example, if you need 10 simultaneous calls, you'll need at least 1 Mbps dedicated to voice traffic. We can help assess your bandwidth requirements during setup.
Can I keep my existing phone numbers?
Yes! We can port all your existing phone numbers to our SIP Trunking service. The porting process typically takes 2-4 weeks and we handle all the paperwork and coordination with your current provider to ensure no service interruption.
How quickly can SIP Trunking be implemented?
Most SIP Trunking implementations can be completed within 24-48 hours once your internet connection is ready and your PBX is configured. This includes testing and optimization to ensure optimal call quality and reliability.
