Unified Communications

Add external calling to the tools your teams already use.

Unified Communications (UC) integrates calling with compatible platforms. If meetings work but public calling is missing, review the platform and licences.

Licences, platform, network, SBC, quality and support are part of the design.

Let’s talk

Office phone and headset for business communications.

How it works

A consistent experience for working, meeting and calling from different locations.

People and devices

UC platform

Identity and services

Collaboration / telephony

Integrate, not just install an app

Connect identity, users, devices and the communications platform. Public telephony requires numbers and compatible integration; online meetings do not imply enabled external calling.

Colt offers integration with multiple platforms. Choose according to the existing environment, needs and support responsibilities.

People and devices

UC platform

End-to-end quality

Collaboration / telephony

A poor meeting can start at Wi-Fi

Analyse device-to-platform quality: radio, LAN, Internet, peripherals and endpoint load. Separate an individual issue from widespread degradation.

Measure voice and video with real users, not bandwidth alone. Training, headsets and configuration also affect adoption.

People and devices

UC platform

Service dependencies

Collaboration / telephony

Separate network and platform incidents

Identity, cloud platform and access can fail independently. Define working/calling alternatives and evidence-based escalation to the correct owner.

A second connection helps with access failure but does not repair tenant or cloud-service outages. Contingency must match the failure type.

Illustrative case: from situation to decision

Situation: The team meets in one application but uses a separate system to call customers.
Option: Assess compatible public telephony integration with the current platform and licences.
Check: Test external calls, numbering, devices and network quality with a pilot group.

Platform, licences, public telephony and integrations must be specified; not every package includes every feature.

Decisions for your project

Platform: Identities, licences, compatibility and external calling.
Experience: Devices, LAN/Wi-Fi, quality and user adoption.
Responsibilities: Support, integrations, data and dependency-specific alternatives.

From design to operation

Pilot different user profiles, validate calls and meetings, then roll out with training and support.
