By replacing traditional ISDN before the planned shutdown, SIP trunks provide your business with flexible, stress free and cost-effective communications delivered over the internet.
The big switch off from BT has already begun, and from 2025 all UK businesses will need to have migrated to SIP. ISDN will no longer be available after 2025; why leave it until the last minute, speak to Red Rock and get your ISDN circuits migrated now.
Using SIP Trunking to Connect to a Phone System
Here at Red Rocks Communications, we'll help you connect your current on-premises PBX to a new SIP trunk and project manage the number port as part of the process. Be it a legacy system that doesn’t support SIP or a modern PBX that does, Red Rock can provide the solution that fits your business.
Internet and SIP
Deploying SIP? Worried about the quality of your internet and its ability to deliver a business-grade service? We’ve seen it before; the client deploys their shiny new SIP trunks over their dirty old ADSL circuit, and they have nothing but problems.
Don’t worry. Speak to Red Rock, and we can guarantee you’ll be given the right advice and solution to provide the levels of service your business needs to operate in the digital world.
Rest assured, the Gamma network has been developed from the ground up to deliver business-grade call quality over its QOS enabled network. Why not bundle in a QOS enabled internet circuit to deliver your new SIP calls in the best possible way.
The benefits of replacing your current system from ISDN
The average cost of a traditional ISDN channel is circa £15 vs our standard SIP trunk channel starting from £5.50. Our Standard and Premium packages include free minutes, so your call charges will be significantly reduced if not removed entirely.
We offer an array of resiliency features tailored to your business. No more disruption to your day to day communication.
Have busy periods? Your SIP trunk channels can be increased/decreased immediately and without any long term commitments. Moving office? In just one call we will move it with you!
