# Plivo vs Vobiz — full comparison

> The complete, domain-by-domain Plivo to Vobiz migration reference: voice call API, call-control XML, phone numbers, SIP trunking, conferences, recordings, sub-accounts, webhooks, SDKs, and pricing/compliance — each with a Plivo/Vobiz mapping and a migration-effort rating.

Vobiz is a near drop-in for Plivo — same `/Account/{auth_id}/...` REST shape, same `<Response>` XML verbs, same seven SDK languages. Most of a migration is mechanical (swap host `api.plivo.com/v1` → `api.vobiz.ai/api/v1`, swap HTTP Basic auth for `X-Auth-ID` + `X-Auth-Token` headers, adjust a few SDK method names); the matrix below maps each domain and rates the effort.
