Hosted Telephone Systems

With a range of Hosted offerings designed to suit every type and size of business, we are well equipped to provide you with the best possible solution, matched to your requirements, and capable of delivering Unified Communications to the degree you are comfortable with. We partner with the biggest names in the industry and offer the most competitive access to these solutions, all wrapped up in our renown customer service, and support arrangements.


SME Hosted:

With no equipment at the customer site and no need for maintenance, a hosted service offers users unique advantages over a traditional on site service. With unmatched flexibility, a hosted service gives the user the option to plug into a data port anywhere in the world and still use the features of the service wherever they may be.

The plug and play nature of hosted lends itself to multi-site businesses or those with a distributed workforce or using home working without the need for multiple systems.

Mainstream offers a ‘simple’ hosted service for smaller users, which includes the most popular features required, including voice mail, queuing, routing and scheduling. With the ability for users to manage diverts and simple changes via a web portal, the system can grow as required with additional features added as needed.

Enterprise Hosted:

Similar to SME Hosted, this is a fully featured telephone solution offering secure connections between handsets and our data centre. The core system has been developed by Mainstream, working with Samsung, to deliver a high availability system that is maintained and hosted by Mainstream at multiple UK data centres. This gives the user the security of knowing that if there is a system fault at one location, services will be automatically re-routed to maintain service.

Developed for use with Samsung smart phones, the user can seamlessly switch between their desk phone and mobile device. Additional modules are available for applications such as call recording, call stats and call centre working. Mainstream will configure your initial system and provide access to an administration portal so the user can make changes without having to contact us.

Hosted Virtual ISDN

With the onset of the big copper shutoff and the programme being already well down the implementation cycle, it is now crucial to consider how that is going to leave your existing Telephone solutions. Many PBX solutions can be upgraded to support the new technology replacements for our existing copper services, but for those that can’t there is our Hosted Virtual ISDN product, which can deliver an ISDN interface to your system, whilst utilising modern IP technology for the connection to the wide world. With a significant investment in a large PBX and the disruption that migrating to a new platform might bring, this is a solid way forward which guarantees your investment in your existing hardware and eliminates user disruption.


You may have heard that ISDN lines will be switched off around 2025, and so you will be forced to upgrade your telephone system.

BT are proposing to cease ISDN from 2025, but Mainstream will continue to provide ISDN services for our customers for as long as they are required and the Hybrid solution from Mainstream ensures you can use your existing ISDN enabled equipment for as long as you wish.

This is ideal if you have recently upgraded the system, but want to future proof your lines and ensure you get maximum return from your assets.

The Hybrid solution from Mainstream digital also provides a simple, cost effective migration path for legacy telephony systems that may be costly to upgrade or unable to operate with the latest digital line technology.
