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. It connects your businesses PBX to the PSTN via broadband, ethernet or private circuit into the national network.

Benefits of SIP trunking for your business voice connectivity

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 all businesses could benefit from a SIP trunking solution. Some of the common questions we come across when discussing SIP trunking solutions with our customers include:

  • Is a 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 our SIP trunking solutions. This means we can identify and fix any issues faster, through our advanced monitoring and diagnostic tools. This combination of best in class partnerships 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 all 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 goes down to my business? Should something like this happen, you can use SIP trunking to minimise disruption to your business. 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 you can keep your existing number, even when moving out of the area, saving you costs on having to reprint, redesign and time taken to let customers know your change of address details. We can also work with your business to transfer your old or existing numbers too so that you can avoid 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 and ones deleted easily. This gives your business greater control over telephony costs as you will only pay for the amount of lines you really need, rather than having to pay for a number of telephone lines that are not used over 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 to make external calls.

Compared to ISDN, Wanstor’s SIP trunking service is less costly per channel and more flexible in 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.
