A single AI phone call is not one system. It is six to eight separate services, each with its own region, and most residency promises cover only some of them. Audio, transcription, model inference, storage, CRM sync and error logging can each land in a different country. Ask for a named region per hop, in writing, rather than accepting one badge on a website.
What this covers
- At a glance: the short answer
- The one-switch myth
- Walk the call: eight hops, eight possible jurisdictions
- 1. The telephony carrier and SIP trunk
- 2. Audio in transit and the recording buffer
This is a technical summary. The full guide — with the tables and worked examples — is on our site: *Where does your call data actually live? Data residency for AI voice agents*.
