Telephony & IP PBX

One system behind every extension in the building.

IP telephony replaces separate phone lines with a single system that routes calls over your network — extensions, transfers, conferencing and call handling managed in one place.

IP PBXEXTENSIONS
01Extensions

Internal numbers across desks, departments and sites.

02Call handling

Routing, transfers, menus and voicemail.

03Conferencing

Multi-party calls without a separate service.

The problem

Traditional phone systems tie an organisation to fixed lines and fixed desks, and every change means an engineer. Adding an extension, moving a desk or routing calls differently becomes disproportionately difficult.

What CSS does here. CSS supplies and configures IP PBX systems and handsets, and integrates them with the network and internet connection they run over — which is the part that usually determines whether call quality holds up.

How we work

From requirement to running system

The same sequence whether the job is one machine or a site-wide rollout.

  1. Understand

    We start with how your organisation actually works — sites, users, existing equipment and the constraints you are operating under.

  2. Design

    We propose an approach sized to the requirement, and explain the trade-offs so the decision is yours to make with full information.

  3. Supply

    We source the equipment and licensing through the manufacturers and distribution channels we work with.

  4. Implement

    Our engineers install and configure on site, and test the result against what was agreed before handover.

  5. Support

    We stay available afterwards — for questions, changes, faults and the maintenance that keeps the environment working.

What this connects to

Most requirements touch more than one area. These are the parts of CSS that usually come with it.
