/**
 * Initiates a new outbound call leg within the current session.  This is a non-blocking command — the next command in the sequence executes immediately while the call is being established in parallel. Call lifecycle events (answer, busy, reject, timeout, hangup, failure) are handled via the `events` property.  The `from` and `to` endpoint types should ideally match. If they differ, the platform attempts to convert the `from` value to be compatible with the `to` type. For example, PSTN supports only E.164 phone numbers, so a SIP address such as `sip:46701234567@acme.se` can be converted to an E.164 number. If the `from` value cannot be converted, it defaults to null (anonymous).
