VOIP – Voice Over IP Telephone Systems

Our phone systems currently run Asterisk based software which has been used in over a million installations worldwide. As well as handling VOIP our systems can be used with traditional analogue PSTN lines and or all types of digital ISDN lines. The Asterisk software at the heart of the phone system is enabled with features such as: voicemail, music on hold, ring groups, hunt groups, call queues and menu systems (for a full feature list see below).

Our VOIP systems are also capable of utilising a device that will route calls to mobile numbers via a mobile network* in order to make further substantial cost savings.

VOIP stands for Voice Over IP where phone calls are made across an IP network instead of a landline, making it extremely portable. This means that a good, business grade broadband connection has the potential to carry up to 15 concurrent calls making VOIP far more cost effective as you will not need to pay for 15 individual line rentals but a single VOIP trunk instead. If you are lucky enough to be in a fibre enabled area your connection could have the potential to carry over a hundred concurrent calls, making this an absolute no brainer for call centres.

VOIP Benefits

Cost savings. The most attractive feature of VoIP is its cost-saving potential.

Number portability. The legacy phone system assigns a phone number with a dedicated line, so you generally cannot move your phone number to a completeley different geographic location. VoIP provides number mobility: The phone system can use the same number virtually anywhere as long as it has internet connectivity.

Integration and collaboration with other applications. VoIP protocols (such as Session Initiation Protocol [SIP], H.323) are able to integrate or collaborate with other applications such as email, web browsers, databases, instant messenger, social-networking applications, and so on. Typical examples are voicemail delivery via email, click-to-call service on a website, voice call button on an email, presence information on a contact list, and so on.
