Call Centres

Pinnacle is certified in selling, installing and maintaining Avaya’s Contact Centre Select and IP Office Contact Center systems. Both provide historical and real-time call statistics, skill-based routing, voice and self-service solutions.

Avaya Contact Center Select
Supporting up to 250 agents, Avaya Contact Center Select is the recommended solution for businesses whose call centre is critical to their business.

Contact Center Select uses SIP and CTI interfaces to communicate with the IP Office platform, allowing access to and control of a wide range of features including call treatments, reporting, unified agent management, and the graphical Orchestration Designer utility.

Avaya IP Office Contact Center
Avaya IP Office Contact Center is the recommended solution for businesses with up to 100 agents who consider the call centre important, but not business critical.

Offering call recording and multichannel (voice, email, web chat) features, it can be deployed across numerous locations with dedicated or virtualised servers. Designed specifically with the needs of SME businesses in mind, IP Office Contact Center offers a simple yet powerful call centre solution for companies where excellent customer service is vital.

Call Recording & Logging

Through its partnership with Oak Telecom, Pinnacle offers Call Recording and Call Logging software that enables you to monitor calls for customer service, staff training and regulatory compliance purposes.

RecordX is a single unified call recording and logging solution for fixed lines, mobile and VoIP that meets all FCA and PCI DSS compliance needs. Pinnacle also supplies Oak Evolve – a transformative web-based solution allowing you to supervise and organise calls wherever you are and using whatever device you have to hand.

Calls and Lines

Pinnacle offers ISDN2, ISDN30 and traditional analogue lines from BT, Colt and Vodafone. We analyse your existing usage to create a calls and lines plan tailored to your business requirements, with recommendations on how you can reduce costs without compromising voice quality.

At Pinnacle we know that any communication disruption can have a devastating impact on your business. That’s why we always recommend resilient systems with backup routes for voice and data traffic. Session Initiation Protocol (SIP) is the business standard for internet-based telephony – SIP trunks delivered over a dedicated leased line ensure high-quality calls at all times, even if other routes fail.

Data Solutions

With a wide variety of advanced broadband solutions from top providers including Gamma, Exponential-e, and Colt, Pinnacle allows you to select the option best suited to your budget and technical requirements.

An independent high speed wireless solution, Urban Wimax frees businesses from the compromises of shared wire infrastructure, providing a dedicated and secure connection without the hassle and expense of laying cable. Best of all, Urban Wimax can be installed within just a week.

4G offers an unlimited high speed data connection to London-based businesses. With no need for a landline, engineer or extra wiring, its simple installation means you can be up and running in minutes.


Don’t limit your business to one area – with virtualised inbound lines from Pinnacle, you can have a permanent non-geographically tied number that never changes, even if you move. This “virtual number” is held in the cloud within a highly resilient voice platform which seamlessly redirects calls to your offices. The line can also quickly be redirected to a different number if required, guaranteeing business continuity in the event of line failure or staff absence.


Video and Audio
Pinnacle specialises in intuitive video conferencing solutions on multiple mobile devices. Plan a conference on your iPad with Avaya Flare, or enjoy the exceptional video quality and multiuser mobile conferencing of Radvision Scopia. Scopia solutions deliver quality video conferencing for up to eight parties on the entry level system, and video can be accessed from your boardroom as well as PC, laptops, tablet and smart phone devices. For audio conferencing solutions, Pinnacle recommends Polycom and Konftel conference units.

Web Conferencing
Take remote conferencing one step further with Web Collaboration, a set of online tools that enables invited guests to work together in a user-friendly yet feature-rich environment. Conference participants can instantly share desktops and applications, edit documents and virtual whiteboards, record minutes and send messages. Every important interaction is then compiled in automatically generated Meeting Reports, which are held for easy access on the Web Collaboration server for up to 90 days.
