  • Voicemail. A professional voicemail service for when you’re out of the office or busy on another call. Voicemail messages are retrieved from your telephone handset or delivered to your email inbox.
  • Call recording. Calls are recorded for compliance, training or monitoring purposes. Recorded calls are encrypted and downloaded from the system (in wav or mp3 format) or played back to agent’s telephone handsets.
  • Click-2-Dial. Automate outbound dialling by clicking on a contact’s phone number to call them. Click-2-dial features can be provided from your existing business applications (e.g. CRM / ERP system) using our API.
  • Interactive Voice Menu. Build multi-tiered voice menus to automatically answer calls, filter calls and route callers to the relevant team within your organisation.
  • Call Queues. Hold incoming callers in line and automatically distribute them to the next available agent.
  • Conference Calls. Agents can instantly join two or more other parties into an ad-hoc conference from their handset.


There are many advantages to running a business telephone system from DMC. Here are some of the key benefits.

  • Agile working. Empower your people to work when, where and how they choose, with maximum flexibility and minimum constraints.
  • Keep your telephone numbers when you move office or switch provider.
  • Flexible rolling contract options. Grow and shrink your subscription as your business requirements change.

  • First class technical support service. Expert, friendly, UK based technical support team providing a fast response to your enquiries.


DMC telephone systems are hardened to eliminate security risks from malicious third parties that could result in data theft, data loss or fraudulent calls (toll fraud).

There are many layers to our security model. Here are a few of our key security features:

  • Intrusion Detection. Proactive monitoring for malicious activity (e.g. DOS attacks or Brute Force attacks) or policy violations. Alerts are flagged on our wallboards and sent to our System Administration team.
  • Encryption of media streams and call recordings. Signalling and media streams between the telephone handset and phone system are encrypted by default. Call recordings and other data may also be encrypted.
  • Full audit trail. Every move and change is comprehensively logged. Administrators can use the audit report to track user logins and every screen that was viewed or configuration change that was made.
  • Inbound call barring. Inbound calls may be blocked if the caller id is not recognised or withheld or if the caller id has been added to a blacklist.
  • Outbound call restrictions on PBX and trunk. Outbound call restrictions may be configured on the PBX (user level, group level or system wide) and the DMC Connect SIP trunk to ensure that users do not run up large phone bills by dialling expensive numbers.
  • PCI / MiFID II / GDPR Compliance options. We have PCI, MiFID II and GDPR compliant solutions for customers who need to record calls and take payment over the phone and store customer-sensitive data on their telephone system.

On Site

An on-site telephone system is installed on dedicated servers at your business premises.

On-site systems can offer long-term cost savings and may be connected to the traditional telephone network (ISDN, PSTN) and more modern VoIP networks.

We recommend on-site systems where customers are locked into long-term contracts with traditional telephone companies or where there is inadequate Internet connectivity or a preference for onsite hardware.


DMC’s cloud platform provides a fully managed Internet-based telecommunications service from diverse data centres with no single point of failure.

Our cloud services are accessed over the public internet and delivered using the SaaS (Software as a Service) model.

DMC build dedicated cloud telephony solutions for our larger customers on their own infrastructure or using third-party cloud service providers (e.g. Bytemark, Amazon Web Services, Google Cloud and Microsoft Azure).


Host your telephony service with a company that specialises in telecommunications systems.

DMC provide co-location services, dedicated managed servers and virtual machines for telecommunications systems only. All hosted systems benefit from uninterrupted power supplies, diverse Internet connections and a fast, resilient network.


Host your own telephone systems in our data centre. Reduce your monthly hosting costs and have full control over your server hardware and upgrades.

Virtual Server

A virtual machine (VM) or virtual private server (VPS) runs a dedicated operating system on shared physical hardware resources.

Dedicated Managed Hosting

Host your telephone system on a dedicated server provided by, and fully managed by DMC. Benefit from the performance of a dedicated server without the inconvenience of installing, upgrading, de-commissioning and disposing of physical hardware.

Business Continuity

Critical application failures can have significant costs to any business. Unplanned downtime can originate from many sources, including natural disasters, network or power outages, human error, or malicious acts.

Failover / High availability

  • Our platform is robust and tolerant of hardware failures, faults and mis-configurations.  All components of the telephone system may be configured in a multi-server cluster topology to ensure that there is no single point of failure in the software. This architecture also provides a highly scalable solution.
  • The system can be hosted across data centres in different locations to drastically reduce the impact of major network outages and to facilitate disaster recovery.

Disaster Recovery

  • We work with you to identify points of failure, analyse risks to your business and to design and implement a business continuity plan that is right for your organisation.
  • Endpoints are portable and can be moved to a different location without reconfiguration. They are able to re-register to an alternative server location to provide continuity of service in the event of a major incident.

Backup & Restore

System configuration and business data (e.g. call recordings, media files, call detail records and management information) can be backed up nightly, weekly or monthly.  Backup images may be copied off the system.
