Cobus, Keeping you connected…

VoIP systems

With a VoIP (Voice over Internet Protocol) telephone system calls are made over an internet connection and can help your business reduce costs, budget effectively and increase the mobility and productivity of staff.. It is easier to install, configure and maintain and you can scale up and down to your business needs. Call costs are low or can be bundled with line rental enabling you to budget every month.

Cloud based solutions (SIP/hosted)

SIP trunks (internet telephone lines) can offer a more flexible and lower cost alternative to traditional ISDN. They connect your PBX telephone system to the local network exchange via a ADSL broadband, ethernet or private circuit connection.

Very quick to install, are ideal for multi-sites and have lots of additional features usually included. SIP trunks can be used with many existing telephone systems and alongside ISDN lines to create a hybrid system, which means you can route your calls accordingly and have the resilience/back-up in case of loss of connectivity.

On-premise systems

These systems have a physical box located on your premise and are connected by wires to each telephone. They rely on ISDN/analogue lines to make outbound calls, so not dependent on your internet connection potentially making them more resilient. They can be upgraded to become a hybrid system integrating SIP trunks.

It can be relatively costly to install new ISDN lines and each system has an initial capacity level that you are limited to, so these need to be taken into consideration when choosing your most suitable system.

Individual Services (line/connection types)

Analogue/ Multi / PSTN Lines – A simple business phone line, one phone number per line. It can be upgraded to multi-line group so a single number can be shared between numerous lines.

ISDN2 Lines/ ISDN30 Lines – Digital telephone lines that allow concurrent calls on multiple channels on the same copper wire.

VoIP – Voice over Internet Protocol allows you to make telephone calls over an internet connection instead of traditional analogue or ISDN lines.

Fibre – A fibre broadband connection is usually a connection between two given points, again usually a business premise and data centre or network node and it can deliver speeds up to 1Gbps. Usually a fibre broadband service is shared, or contended, with other users but will offer superior speed, throughput, and resilience over standard copper ADSL broadband.

Leased Lines – A dedicated circuit which connects two end points for transferring and sharing data between them and benefits from a non-contended connection without any sharing.
