    — The Problem —

    Enterprise Voice Is Still Fragmented

    Most enterprises run a patchwork of regional SIP carriers, ageing on-prem SBC appliances, and disconnected UC and CCaaS stacks — driving up cost, risk, and integration debt.

    Fragmented SIP carriers per country
    Costly on-prem SBC hardware refresh
    Manual number provisioning & porting
    No unified policy across UC & CCaaS
    Regulatory blockers in restricted markets
    Limited fraud & toll-bypass protection
