Optimal routing

Voice Managed Services routes every call to the most qualified operator

  • No missed calls
  • The customer comes first through routing to the right operator
  • Clear statistics about incoming calls

Service disruption? No problem!

Voice Continuity ensures the rerouting of incoming calls that wouldn't be answered during technical downtime, hardware-related maintenance or a national or international emergency.

  • Configure this on a per number basis or for all numbers together via:
    • a mobile application on a smartphone
    • MyProximus
  • No additional hardware investment or change to infrastructure needed
  • Accessibility and continuity of business activities are guaranteed

This is also an option

Outsource the routing to Proximus in case of a technical failure. Then, a telephone call is all that's needed to activate the pre-established routing plan.
