Hosted...the future

If you are using a PBX in your organisation, it could be time to consider moving instead to a hosted solution to realise all the benefits that IP cloud telephony offers. 

Gamma are one of our hosted partners and one of the UK’s largest providers of voice over IP, switching in excess of 650 million minutes of calls per month over its soft switch infrastructure. Built into this infrastructure is the Horizon Hosted telephony platform, which gives over 100,000 UK users access to high-end telephone system functionality without the cost associated with owning such a system. 

Using latest resilient technology simply put, hosted telephony is a telephone system that resides in the cloud rather than in your office. Users access the system through a standard IP handset and via an internet connection.

SIP VoIP Technology

SIP Trunking is fast becoming the standard based replacement for traditional ISDN. If your internet connection is voice-capable, having dedicated SIP channels on it can both save you money and guarantee your calls will work.

We use the largest, most resilient SIP network in the UK which uses your existing data pipes or leased lines. There’s the option of free calls between sites for multi-site businesses.

SIP Trunks connect your PBX to the PSTN via broadband, Ethernet or private circuit into the national network. Our SIP Trunks work seamlessly with each of the leading IP PBX brands in the UK market.

SIP gives you a flexible set of features, including easy call routing to another centre, great for business continuity and something you can’t do with traditional lines.

Benefits of SIP

Compared to ISDN our 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, as standard, it delivers extremely robust business continuity.

Using the latest next generation IP technology (SIP) this will enable you to future proof your communications and put you in a position to combine your voice and data services to greatly enhance your savings and features. 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.

From the simple money savings on calls and rentals you can also scale up and down really quickly all with the added benefit of fraud protection.
