SIP trunking...What on earth is that?! Don't panic, we could go into lots of technical detailing, in fact we could talk for hours about it, but we don't want to scare you! Of course, if you would like technical information, please contact us and we'd be delighted to help.

So, what is SIP trunking? Contrary to popular belief, it doesn't refer to the way an elephant consumes a hot beverage...our official definition is that it is the term for the telecommunications solution that takes your existing boring phone system, connects it to our IP network, and turns it into a super IP phone system. But why would you want to?!

Well, if you upgrade your existing phone system to an IP phone system with SIP trunking, you get...
• Complete flexibility and movement of numbers
• Longevity to your existing hardware
• High quality calls
• Improved resilience and disaster recovery options
• Free internal calls and transfers (even between different sites)
• Free calls to other companies on our IP network
• Low cost calls to numbers on the traditional telephone network
• Low cost international calls
• Free support from our excellent IP Telephony Support Team from the beginning to the end, and beyond

It could be that your existing telephone system is already IP-capable, if so, all we need to do is connect our IPDirectConnect service to it, and hey presto, you’ve got an IP phone system. Your system is unlikely to be IP-capable if it is a bit older, but don't worry, we can attach our clever little box called Converter which, when plugged into your existing system, acts as a VoIP gateway to the IP network and provides you with exactly the same service.

SIP trunks are an alternative to ISDN (digital) lines. It is important to realise that although they are similar, they are not like for like services. SIP trunking is a more cost-effective option for a number of reasons. In relation to expansion, additional lines can be added at a fraction of the cost (and indeed time) than deploying ISDN would entail. Also, all internal calls and transfers are free of charge, and those which break out onto the traditional network (PSTN) are greatly discounted.

SIP trunking is easy to install, and compatible with most phone systems. It is available over ADSL, SDSL, LLU or private circuits. SIP trunks are easily scaleable, and provide genuine resilience and improved business continuity and disaster recovery.
