3CX Phone System
Flexible, feature-rich telephony that adapts to how you work
3CX is a modern business phone system that unifies voice, video conferencing, messaging and presence — all accessible from desktops, mobiles or desk phones. Designed to scale from small teams to distributed offices, it gives you the flexibility of on-premise or cloud deployment while keeping management simple and intuitive. BSAS specialises in hosting and supporting 3CX so your communications are reliable, secure, and always up to date.
BSAS Hosted VoIP / Cloud PBX
Cloud voice that removes hardware and complexity
BSAS Hosted VoIP delivers a full phone system in the cloud with built-in resilience and easy scaling. With no bulky PBX hardware to manage, you get simpler installs, flexible user management, and consistent performance regardless of where people work. Cloud PBX also reduces your capital cost footprint and shifts voice to a predictable operational model.
Teams Voice
Integrated voice calling inside Microsoft Teams
MS Teams is one of the world’s most widely used collaboration platforms, and BSAS extends its capability with enterprise voice. With Teams Voice, your people can make and receive PSTN calls directly within the Teams interface — eliminating context switches between apps while improving call quality and management. This approach reduces complexity and cost when compared with having separate telephony and collaboration silos.
SIP Trunks
Cost-effective, resilient voice connectivity over IP
SIP Trunking replaces traditional ISDN/PSTN lines with internet-delivered voice channels that support inbound and outbound calling. BSAS SIP trunks deliver excellent call quality, built-in resilience, and lower call costs, with enhanced features such as call reporting, routing and disaster recovery options. They integrate cleanly with modern PBX platforms and are a future-ready foundation for your voice estate.

SIP Handsets
Smart, professional desk and SIP handsets from Yealink
Yealink handsets deliver reliable, high-quality voice for offices, hot desks, and hybrid working environments. Designed for clarity and ease of use, they integrate cleanly with modern phone systems like 3CX, Hosted VoIP, and Teams Voice — giving your users consistent call experience, simple management, and professional performance across desk, cordless and executive models.
Tom and the BSAS service team have given us great service ever since we partnered with them in our 3CX journey. Nothing is too much trouble and quick to respond to our needs no matter how minor. We would not hesitate to recommend their services.
Arken POP International Ltd
As a non-profit, we have relied on BSAS for many years to provide us with reliable, cost-effective broadband. We have always had great advice, fair pricing, and the support desk has always stepped up to the mark and held the big suppliers to account when needed. We've just signed up with BSAS to provide our head office Internet lease line, which I am confident will be looked after just as well. The sales team are helpful, there in person when needed, and offer accurate, practical advice on the best way to provision Internet connections across England and Wales.
Scripture Union
We have used BSAS Telecoms as a supplier for well over 15 years now and there's a reason we have kept with them. Sales and support are very responsive and effective at dealing with our requests. We moved all of our mobile phones from Vodafone to BSAS because it took so long to deal with Vodafone and there were always mistakes made. Now we have everything under one roof, including Internet lines and VoIP, it makes it much easier to manage all Telecoms now. Tom is our new account manager and he can't do enough for us. I highly recommend working with BSAS for your Telecoms needs, they offer a personal touch and always deliver.

DWR Veterinary Specialists
I have used BSAS for many years for all our communication requirements. We had an EFM connection through them which was recently updated to a Leased line. This has provided a massive increase and improvement in bandwidth which has allowed our company to utilise several other services. The install and upgrade was seamless and well managed throughout.
