SIP TRUNKING

The right voice product can be crucial to your success. That’s why we don’t limit you to just one option. Our products and services will give you the right tools to create your perfect converged solution.

What is SIP?

Session Initiation Protocol (SIP) Trunking is a way of providing telephone lines using data rather than fixed lines. It gives you the ability to make and receive calls using IP technology without needing to completely replace your PBX.

We have taken the time to ensure our SIP offering meets all our partners’ needs. That’s why we offer two types of SIP, with options to enhance your service.

How SIP Trunks work

SIP Trunks are a virtual voice service made up of a number of SIP channels that are delivered to your premises over a Broadband or Leased Line connection, breaking out to the PSTN network allowing both ‘on-net’ and traditional telephone calls. Most PSTN and ISDN numbers (including Direct Dial In (DDI) and non-geographic Number Translation Services (NTS)) can be easily ported across. They are also compatible with most leading PBX systems so any business with an existing PBX can switch to using our service immediately.

The number of SIP channels your service can support is dependent on the bandwidth of your connectivity solution. For less than four channels, a dedicated ADSL connection is sufficient, however for more than four, you will need an FTTC or Leased Line connection depending on the number of channels you require. We can support up to 50 calls per second and up to 5,000 users. We use two standards of codec that will alter voice quality depending on available bandwidth:

How SIP Trunks will benefit your business

Reduced costs	In addition to no significant install, setup and maintenance/upgrade costs, you will save up to 50% on line rental and typically up to 25% on call costs compared to a traditional ISDN service. Internet-based calls and internal calls across your organisation are completely free, even to international sites.
Full scalability	Unlike traditional ISDN services, the number of SIP channels you have can be scaled up or down without the need for any infrastructure changes, no matter the size of your business. As long as you have the necessary bandwidth to cater for the extra channels, we can instantly provide them upon request on a ‘pay as you grow’ basis. These can be on a temporary or permanent basis and are perfect for seasonal voice demands or to support periodic sales campaigns etc.
Seamless continuity	SIP Trunks offer complete number portability. Instantly re-route your calls to an alternative location if an emergency should happen, without incurring any call-forwarding charges and keep your existing numbers when moving out of an area. Our SIP Trunk service can be used with your current handsets and PBX systems located on-site or hosted in our secure data centres.
Consistent quality	We provide an end-to-end service with 99.95% availability, supported by strong SLAs. As SIP Trunks run over our core network, they are inherently protected by the highest level of security. Load-balancing is used during peak hours or periods of heavy demand to help maintain resilience and overall quality of your service.
UK-based support	Dedicated account management and completely unscripted customer and technical support with 24/7/365 incident reporting. We aim to answer all calls within 60 seconds and will resolve 70% of problems on the first call.
