Gamma supplied 120 SIP channels to De Montfort over their existing JANET connection, with the option to increase the number of channels for the duration of the clearing period.

In preparation for an expected bumper clearing day at Northumbria University, Gamma backed up the SIP-based solution with our ‘Hosted for Clearing’ solution. Our Horizon cloud-hosted telephony platform is installed on a temporary basis and is instantly scalable so it can be enabled during busy periods such as clearing, or as required.

Northumbria University

Gamma provisioned SIP trunking over JANET to the college’s Cisco PBX and ported over a block of 399 numbers seamlessly and without fuss or disruption. A separate, diversely routed fibre connection will, when added, provide robust connectivity back up.

City of Glasgow College

Gamma provisioned managed data links for Virgin Wines’ three sites providing Ethernet, SIP and Internet connectivity to complement its existing ISDN telephony. As the business grew we were asked to provide additional capacity and resilience and this was achieved by adding further links using diverse routing.

Hosting Cathay Pacific’s 100 DDI numbers in the cloud, Gamma’s Inbound solution means the airline is no longer relying on a third party to implement redirects on its behalf.

Gamma’s recommendation for American Golf was to consider our MPLS based WAN solution – Converged Private Networks (CPN). We converged their voice and data on to a single platform. This easy-to-manage solution provides strong connectivity and enables them to access business critical applications across multiple sites. CPN has ultimately improved the customers internal communications, providing American Golf with more flexibility and above all is helping them to achieve substantial cost savings.

Gamma provided Thistle with an 03 number range to match their requirements and delivered bespoke commercials, ensuring this delivered value to the business. Thistle has now transferred every inbound number to Gamma. Now the platform allows them to make instant changes, 24×7 via the web-based portal, putting them in complete control, without having to wait for a third party supplier.

bira chose Gamma’s Horizon hosted, cloud-based platform to support more than 70 extensions across both its locations. Connected by our Assured ADSL service and by a third party Ethernet solution respectively, Horizon met all bira’s requirements for continuity and, importantly, allowed call answering and handling at both locations from easy-touse ‘drag and drop’ reception consoles.

We replaced NEL’s ISDN connections with two Ethernet load balanced connections back to two different Gamma data centres, giving 300 SIP connections. We worked with NEL to ensure that the porting of some 3,000 DDI numbers was seamless. NEL also chose to take our Inbound service, giving it direct and instant control over incoming call routing.

Hudson’s ISDN lines and on-premises PBX have gone. In their place Gamma’s Assured ADSL with guaranteed quality of service provides the highest quality voice connectivity to the outside world from new desk-top SIP phones, while Gamma’s Horizon solution delivers the intelligence that allows Hudsons to manage the system. The solution is priced on a per-user basis with all line items rolled in to a monthly fee with no up-front costs.

Keatons had Gamma deploy their Horizon hosted IP telephony platform. Needing no on-site hardware beyond the phone handsets themselves it is quick to provision new lines, rapid and easy to make changes in the way calls are handled and routed, and is highly flexible in the way it operates. Keatons staff like Horizon’s ease of use, its simple programmability and the full function Polycom phones supplied as standard.

Gamma brought the Knight Frank branch network up to date by replacing some 600 legacy PSTN lines and ADSL links with an Ethernet wide area network, delivering a 40 times increase in capacity and generating new opportunities for video and voice.

Gamma provided Progress Housing Group with more than 100 single analogue connections, over 30 multiple analogue connections and three ISDN30 lines across the Progress Housing Group estate to meet its voice communications requirements. For data we provisioned an additional 42 ADSL broadband connections at the Group’s locations. Our ability to support both geographic and non-geographic numbers within the network was a major plus point, giving Progress Housing Group more control over call handling and routing.

The British Heart Foundation has a long standing relationship with Semafone partner, Gamma, who provide the SIP Trunk related services for the delivery of phone calls into the BHF. Semafone worked very closely with Gamma during the project scoping phase and were able to map the BHF’s requirements against PCI DSS compliance.

British Heart Foundation

ABHB chose our combined calls and lines solution. Using Gamma SIP Trunks from the cloud wherever possible, the move involved changing a large number of lines over at smaller, outlying locations as well as those at high-volume central sites.

Aneurin Bevan Health Board

Gamma project managers helped Hidden Hearing run the entire migration project away from their legacy solution to our own next generation network. This ensured a smooth delivery of services on time and to plan. Phone connections at branches were replaced with MPLS virtual private network connections with ISDN available as backup, and analogue as further backup still – a real belt and braces approach.

Hidden Hearing

Using a number of public reference sites – including one other constabulary – Gamma were able to demonstrate our SIP solution to the Norfolk and Suffolk team. We then implemented 300 channels of load balanced SIP over 100Mbit diversely routed connections to Cisco PBXs at two of their data centres.
