Telephone Systems

Incom Systems can advise and supply telephone systems to best suit your business needs. This can often be accomplished using existing trunk lines and provide enhanced telephony services to the user. Voicemail, Auto Attendant and Direct Dialling In (DDI) are all useful additions to business efficiency and are supported on most new systems as standard.


We are able to supply traditional telephone Systems using digital technology to run on existing or new analogue or ISDN2e/30e digital trunk lines. These will often make use of existing voice cabling without the need to incur extra cabling costs.

PSTN stands for Public Switched Telephone Network and an analogue PSTN line is similar to the one you probably have for your telephone at home.

ISDN stands for Integrated Services Digital Network and gives you Voice, Data & Video on one network with increased speed, clarity and reliability.

We offer design, support and maintenance for various systems - we are business partners of Avaya, Aastra/Ericsson, LG, Mitel, Panasonic, Samsung, NEC & Siemens.


IP Phone Systems unify business communication methods into a single, easy-to-manage, and simple-to-use solution that was designed from the ground up for IP networks. These are normally completely integrated systems that scale seamlessly from 1 to 10,000 users, and can be installed in single or multi-site environments.

There are a plethora of applications available, ranging from Voicemail, Automatic Call Distribution and Automated Attendant to Multi Media, Email and Data Application Integration.

These systems may run on specific manufacturer hardware platforms, or be available to run on standard server hardware located anywhere on the IP network. The result is a single-image system across all geographic boundaries with complete feature transparency and integration of all the required applications.
