Technical Director
Regional operator
“We had a complex SIP legacy with three different vendors. Nicolas mapped the existing setup and proposed a convergence architecture that held up. No surprises at deployment.”
CIO
Retail store network
“9,000 RingCentral endpoints migrated across 45 sites in 4 months. Not a single critical ticket in production.”
IT Manager
International educational network
“Our engineers are autonomous on Teams Voice after two training sessions. We no longer call vendor support for standard cases.”
