Voice services remain the bedrock of business-critical communications and new technologies present many opportunities for companies to improve performance through better customer service, increased productivity and greater collaboration. Our focus is on helping you realise the potential of the latest voice services so that you can work smarter and more efficiently.

However, with BT ceasing the supply of ISDN and PSTN services this year (2020 – the other major carriers already have) and withdrawing them completely by 2025, any firms still using these legacy technologies must now look to replace them with a Voice over IP (VoIP) solution such as SIP trunking.

As well as laying the foundations for a future-proof solution that supports Unified Communications and Collaboration, converging voice and data networks to a single IP-based infrastructure provides numerous cost benefits and operational improvements:

If you’ve just invested in a new IP PBX, or have other reasons to prefer an on-premise system, we have years of experience in maintaining and supporting all leading IP phone systems, including Cisco, Mitel and Avaya.

Leveraging our strong relationships with the best network operators, SIP providers and hardware vendors, we can tailor the perfect solution for your business, supported by world-class customer service from a team that really cares.

However, firms of all shapes and sizes, from all sectors, are increasingly opting to ditch their PBX in favour of a cloud-based telephony solution…


Is your current PBX holding your business back? Should you move from your physical on-site phone system or hybrid cloud solution to a fully hosted voice service?

The benefits are many – firstly, moving to cloud telephony removes the need for an on-premise telephone system and all of its associated costs:

MaintenanceSoftware updatesIT resourceElectricity … and of course depreciation in the value of the kit itself. With a hosted solution, none of these are an issue.

Add to that the potential vulnerability of on-site systems to damage, flooding, fires etc., and their relatively limited shelf life, and there is a strong argument for moving to a hosted telephony service, with the many additional features that come with cloud-based solutions.

Compliant hosted call recording


Are you a regulated financial firm, required to record and store telephone calls for compliance with MiFID II, SYSC 10A, Dodd-Frank, FINRA or any other legislation?

Is finding a truly compliant cloud-based call recording solution stopping you from moving to a hosted telephony service?

Or are you simply looking for a way to replace your existing call recorder to get away from exorbitant charges and poor service?

Regardless of whether your PBX is on-site or cloud-based, DoubleEdge offer several fully compliant hosted call recording options enabling firms, both large and small, to meet and even exceed all relevant regulatory requirements.
