SIP Trunks for Business from Wanstor, the IT Services Company.

SIP trunks offer a more flexible and lower cost alternative to ISDN for inbound and outbound voice calls. SIP trunking is a standards-based replacement for traditional ISDN, which connects your businesses PBX to the PSTN via broadband, ethernet or private circuit into the national network.

When delivering calls over SIP trunks, there are key elements to making sure that call quality is maintained and equivalent to that experienced on ISDN digital lines. At Wanstor, we believe that all businesses could benefit from an SIP trunking solution. Some of the common questions we come across when discussing SIP trunking solutions with our customers include:

  • Is an SIP trunking solution resilient? SIP trunking is now a mature service enjoyed by thousands of businesses across the UK. At Wanstor we work closely with all major telephony network providers. Additionally, we deploy best in class telephony network monitoring software in all of our SIP trunking solutions. This means we can identify and resolve issues faster through our advanced set of monitoring and diagnostic tools. This combination of best in class partnership and technology keeps our customers SIP trunking solutions reliable with 99.99% uptime.
  • What’s the call quality like? From the moment we connect your SIP trunking service, your business will benefit from the reliability, resilience and quality that comes from working with one of the UK’s leading SIP trunk providers. We proactively monitor and manage quality of service across our entire network, and support all major telephony and networking technologies to provide your users with a high quality call experience.
  • What happens if the internet or power to my business goes down? Should something like this happen, you can use SIP trunking to minimise disruption. For example, if your Birmingham branch has to close in an emergency and you need the calls routed to London immediately, Wanstor’s SIP trunking solution can do this for you.
  • We are planning an office move - what happens then? SIP trunking has number flexibility built into the solution. This means that you can keep your existing number, even when moving out of the area, saving you costs on having to reprint and redesign communications material, along with the time taken to update customers of your new address details. We can work with you to transfer your old or existing numbers as well, avoiding expensive Remote Call Forwarding charges.
  • What if we want to add or remove some of our lines? SIP trunk solutions are extremely flexible, and new lines can be added or deleted easily. This gives your business greater control over telephony costs, as you only pay for the lines that you need as opposed to any lines that are not used over the course of a long term contract.
  • How does SIP work with other business networks and applications? Wanstor’s SIP trunks are integration tested and approved to interoperate with all SaaS telephony offerings including Skype and Jabber. This allows your business to directly connect to its telephony platform of choice when making external calls.

Compared to ISDN, Wanstor’s SIP trunking service is less costly per channel and more flexible in terms of how and where geographic telephone numbers can be used. It’s also quicker to install and provision, and delivers robust business continuity. The service can support connections ranging from two channels for small PBX-equipped businesses to an unlimited number of channels for large enterprises and contact centres. Any business with a PBX can switch to Wanstor’s SIP trunking service and benefit from a more flexible, less expensive and more resilient phone service.
