Why choose SIP Trunks?
How resilient is SIP trunking?
SIP trunking is now a mature service enjoyed by thousands of UK organisations and this alone is testimony to the reliability of SIP. For added reassurance while you switch to us, SIP trunking can even be used with existing ISDN connections to ensure the transition goes smoothly.
Owning our own national network means we can identify and fix issues faster, through our advanced monitoring and diagnostic tools. It's a combination which has helped us win many major UK Fixed Line Network awards in recent years and one of the reasons more and more businesses are specifying Gamma SIP Trunks.
What happens if our internet or power goes down?
Should disaster happen, you can use SIP trunking to minimise disruption to your business. For example, if your London branch has to close in an emergency, and you need the calls routed to Manchester immediately, Gamma SIP Trunks can do this and at no extra charge to you.
What if we want to add or remove some of our lines?
SIP trunks are valuable for businesses with seasonal voice capacity requirements where more lines can be quickly and easily implemented with no long term commitments, for example when running sales campaigns.
Conversely, if your business has multiple sites with ISDN connections into each, using Gamma SIP Trunks you can reduce the number of ISDN connections that your business requires and also reduce the maintenance costs on all of your various PBXs. At the remote sites you are left with just the cost of an IP connection and the handsets that you need and you can then pull all the telephony traffic back into your centralised PBX.
What's the quality like?
From the moment we connect your SIP trunking service, you will enjoy all the reliability, resilience and quality that comes from working with the UK's leading SIP trunk provider. We proactively monitor and manage quality of service across our entire network - it's the underlying network quality that makes a real difference to SIP trunking. And as a consequence we are able to support both G.729 or G.711 codecs.
What if we're moving office?
Number flexibility with SIP trunking means that you can keep your existing number, even when moving out of the area, saving you costs on printed company literature and stationery whilst maintaining the perception that you still have a presence in the area you've moved from. We can easily transfer your old or existing numbers too so that you can avoid expensive Remote Call Forwarding (RCF) or call diversion charges.
With CLI flexibility you can also decide which number you want to display on a call by call basis - great for contact centres.
Does SIP work with other business networks and applications?
Gamma SIP Trunks are integration tested and approved to interoperate with Skype® for Business, allowing you to directly connect to the platform to make external calls.
We're also a Janet-connected partner with an interconnect to provide voice services through Gamma SIP Trunks to the Janet community. Janet is the network dedicated to the needs of research and education in the UK, connecting institutions to each other, as well as to the rest of the world.
