Unified communications & contact centres
IP telephony, unified communications and contact centres.
This is where UCC Experts started. Our engineers audit, design, migrate and troubleshoot voice and collaboration environments, from legacy PABX systems through to Teams telephony.
What we hear in a first meeting
- “Our PABX is no longer maintained and nobody dares touch it.”
- “We want to move telephony to Teams without losing the switchboard.”
- “Calls drop randomly in the contact centre, and we can't find out why.”
What we do, in practice
Telephony audit
Inventory of equipment, numbers, call flows and contracts. What can stay, what must go.
IP telephony / ToIP
Design and deployment, network quality of service, multi-site telephony.
Unified communications
Presence, messaging, conferencing, mobility: a coherent environment for teams.
Microsoft Teams & Teams telephony
Number portability, switchboard, call queues, gateways with the existing environment.
Videoconferencing
Equipped meeting rooms, interoperability, user onboarding.
Emergency telephony
Emergency handsets, continuity in case of outage, backup for critical lines.
Contact centres
Architecture, integration, call routing, evolutions and support on Cisco UCCE / UCCX-type environments.
Architecture & troubleshooting
Voice diagnostics, quality, signalling, routing. Trace analysis down to the root cause.
Migration of legacy environments
Phased rollout, old and new systems coexisting, without interrupting call reception.
User support
Documentation, short training, presence at launch.

Evolving a contact centre
New flows, revised routing, stabilised and operable platform.
Voice troubleshooting
Quality, drops, routing: root cause identified and a documented stabilisation plan.
Multi-site telephony
Shared numbering plan, cross-site backup, supervision.

Do you work on multi-vendor environments?
Yes. Cisco, Avaya, Alcatel-Lucent, Siemens, Snom or Microsoft: we start from what you have.
Can we keep our numbers when moving to Teams?
Generally yes, through portability. We check this during the audit.
Can you step in on an ongoing incident?
Yes, troubleshooting is one of our long-standing areas of expertise.
