When we shift your telephony to SIP, we help you to unlock the cost and efficiency benefits of operating from a future-proof, internet-based communication network.

By transitioning your business to SIP trunking, you get a versatile communication framework that offers a host of bottom-line benefits. A gateway to unified communication, minimal set up, significant cost savings and an immediate ROI – it’s easy to see why SIP has become so popular with our clients.

We help businesses transition to cloud-based calling. SIP is a communication protocol used for initiating and terminating real-time sessions between IP (internet protocol) devices, allowing you to make and receive calls over an internet connection. Moving your telephony to an internet connection removes the need for (and cost of) traditional phone lines.

When we help clients make the transition to SIP calls, we first ensure your network infrastructure is ready to support SIP traffic. We assess your current bandwidth provision and exiting phone number ranges suitability for porting. This ensures quality of service and continuity for customers and stakeholders. 

  • A route to VoIP. SIP is a way for businesses to transition to voice communication over IP networks. 
  • Enhancing collaboration. The SIP protocol is recognised for supporting remote working and facilitating more efficient workplace communication.
  • Unified communication. SIP helps businesses tackle communication fragmentation and lays the foundations for unified communication solutions.
  • Simplifying communication. Removing legacy phone systems and excess communication platforms streamlines your infrastructure and reduces the cost of collaboration. 

With the upcoming ISDN switch off, we’re helping businesses to transition to SIP. It’s a way to modernise your communication systems, ensuring continuity and opening up the potential to leverage the benefits of unified communication.”
