The investment in the UK communications network has made the new fibre infrastructure widely available and affordable to every type of business. Meaning IP based solutions such as SIP and VoIP are the top alternatives for businesses.

What is SIP?

SIP (Session Initiation Protocol) is a signalling protocol used for multimedia communications, which determines the rules of how two points set up, manage and terminate a connection.

In the past SIP did suffer from reliability issues due to inadequate underlying Broadband connections. These problems have now been resolved due to large scale connectivity enhancements and Service Level Agreements now being offered by providers.

What is VoIP?

VoIP (Voice Over Internet Protocol) is the IP-based version of telephone line which uses packet-switched telephony, where voice, data or video travels to the destination in network packets over the Internet. Once arrived, the packets are assembled in the correct order.

VoIP is a Cloud based telephony solution which moves your whole phone system online, so all your calls are sent over your Internet connection. The digital Cloud based phone systems offer a wide range of additional features such as IVRs (Interactive Voice Response), wallboard, call recording, receiving voicemails via email, call queuing and Unified Communications – being able to access the system on multiple devices such as a mobile, tablet and desktop from virtually any location.

Top 5 Benefits of SIP and VoIP
