How Does SIP Trunking Work?

Leverage your existing PBX investment

Save up to 70% by replacing your expensive dial tone
If you are looking to cut cords and switch to IP-based communications entirely, particularly for business communications needs, Session Initiation Protocol (SIP) is the solution you have been looking for. SIP is designed to elevate the use of VoIP and eliminate the need for a landline or traditional T1 line for business use.
SIP is an interesting approach. It operates using a traditional PBX system, which means you don’t have to invest in new hardware or completely redo your internal communications channels.
Vision Voice’s SIP solution sits in between Voice over Internet Protocol (VoIP) system and the internal PBX to allow for traditional routing of calls over IP. SIP trunking offers a long list of benefits that traditional PRI or T1 lines cannot offer, including:
What can SIP Trunking do for you?
The Benefits of SIP Trunking with Vision Voice
A Cost-Efficient Solution
You no longer have to pay for PRI or T1 lines upon switching to SIP trunking, which means you can reduce your communications cost by a whopping 70% each month. You also leverage your existing PBX system, which means the cost of switching to SIP is incredibly low.
As a cost-efficient solution, we designed our SIP service to be scalable. Rather than paying for lots of lines at a time – and paying for lines you don’t really use – you can start with as few as five channels and scale the SIP system up at any point.
Combined, these benefits make SIP trunking suitable for growing businesses who want to stay lean.
Leverage Cloud
SIP runs in the cloud using IP-based infrastructure, so it is easy to see how you can integrate your voice and data services to save more on both. Integrating the two solutions also make managing them easier.
At the same time, moving to the cloud comes with its own benefit. The Vision Voice Elastic SIP Trunking can be allocated to individual departments or managed as a comprehensive solution. It also integrates seamlessly with other solutions in our line-up, including Cloud PBX and UCaaS.
Robust and Reliable
Reliability is never an issue with SIP. The entire platform runs on multiple redundancies that are native in the cloud environment. The cloud infrastructure itself is designed to handle spikes and high loads without sacrificing performance and reliability.
Add the fact that you can add more features – or even scale down if needed – at any time, and you have a robust solution for your call routing needs. Switching to SIP trunking is an easy investment to make; the ROI is so high that you don’t want to pass up on the opportunity.
