Netserv is a managed IT, Telecom and Internet service provider with offices located in the UK and Spain. Netserv supplies VoIP based SIP trunk services throughout Europe.

The Challenge

NetServ was suffering call breakup and jitter issues from its own phone services as well as those provided by customers. It needed to improve the quality of lines and calls.

“Line quality was having a serious impact on calls and we were getting as many as twenty issues a day,” explains Dave Gessey, Netserv Technical Director. “A problem every hour doesn’t give customers much confidence in VoIP.”

The Solution

VOIPBOX links NetServ and its customers throughout the UK and Europe. A VOIPBOX Server located at a datacentre in the UK terminates all of NetServs trunks. A VOIPBOX client located in its European office links all phone services centrally then connects them to the server in the UK.

VOIPBOX ensures that all call traffic is prioritised thereby reducing existing latency on the line and improving user experience and overall call quality. It delivers not only increased bandwidth utilisation and improved security, but also total resilience for VOIPBOX enabled links by using secondary bandwidth routing (thereby ensuring that no calls are lost). VOIPBOX is also capable of utilising “Vibe Link Bonding” (VLB) combining multiple broadband connections to deliver solutions to clients where bandwidth is restricted or greater resiliency is required.

Installed behind existing routing equipment VOIPBOX ensures a simple and straightforward installation and commissioning process. VOIPBOX works in point-to-point situations or in conjunction with an authorised Service Provider offering VOIPBOX enabled services.

Dave Gessey summarised: “Deploying VOIPBOX was simple, with very little impact on other business processes during setup. It’s been very reliable and support from ApplianSys has been extremely flexible.”
