SIP TRUNKS

Connect your PBX to any number, anywhere, anytime.

SIP based services provide flexibility and leverages your existing IP infrastructure. Using our network to deliver calls and services when and how you want them. Logic within the DMV network responds and protects to changes from either loss of service or outage.

What is a SIP?

A SIP Trunk is a facility provided by DMV that allows the placing of outbound calls and the receiving of inbound calls using an internet connection, rather than using an ISDN line. Calls to and from the PSTN are supported. They are fast becoming the standard technology that allows businesses to make and receive telephone calls without the need for an expensive ISDN circuit. The Quality of Service (QoS) has contributed to its increasingly widespread adoption. Session Initiation Protocol (SIP) is used to set-up and 'tear-down' telephone calls over IP networks, including the internet. It is this VoIP protocol that is most widely supported by modern devices, including IP-enabled PBXs.

Why use SIP?

Having separate voice & data networks is a legacy from the technology used for voice and how data connectivity has grown to provide huge amounts of throughput for everyday communication. The switch from voice networks carrying data, to data carrying voice is a reconvergence of voice & data after a 20 year split. As the withdrawal of ISDN has been announced, voice networks move more and more towards SIP. We began this move 10 years ago, as it appeared obvious that true convergence was always going to happen. Voice & data convergence reduce cost and enables better functionality, bringing modern day flexibility to voice.

Numbers - UK or International

DMV has millions of UK numbers covering the whole of Great Britain. All ready to instantly provision and commission onto your PBX. Need international numbers? They can also be ordered on our portal and delivered via SIP.

Number Porting

Moving location or just want to move to SIP? You can keep all your numbers which will be moved over to DMV. We realise your numbers are important to you, so a dedicated provisioning team look after the process.

Fraud Detection

Vital for any business with call traffic due to the risk of fraudulent activity within the industry which is not just limited to SIP. Fraud is not new to telecoms industry but DMV's approach to managing the risk of fraud is included across all our SIP trunks.

Auto Failover and Disaster Recovery

If your PBX doesn't respond or register regularly DMV will automatically route the call to an alternative number landline, mobile or PBX. Find our that your PBX is down before your customers do. Monitoring and recovering from a number of voice issues can easily be setup on the DMV portal.

Call Recording

All in and outbound calls are recorded, saving the expense of onsite call recording equipment. Once your lines have been added to the recording, you will be provided with a portal account to access all recording and download when and if required. Simple and easy to administer and use.

Convergence

Allowing all types of communication: voice, data and video to use on the same network had been around for many years. The efficiencies can be great but must be integrated correctly. DMV have a strong background in converging the network.
