What happens to our existing numbers during migration?

We manage port-in requests end-to-end. Numbers stay live throughout the process and there are zero carrier fees on any port direction. A dedicated migration lead runs your cutover.

Is UCaaS priced per user or per channel?

UCaaS is priced per user with unlimited calling minutes inside your region. Video, messaging and wholesale termination are included in the same license.

Do you support hybrid teams across multiple countries?

TKOS operates global PoPs with local SBCs. Provision users in any country, route calls to the nearest PoP, and manage everything from a single admin tenant.

How long does rollout take for a 200-seat team?

A typical 200-seat cutover runs in two weeks: week one is provisioning, identity and device pilot; week two is full team migration with parallel running and a dedicated cutover lead on standby.
