Source note · Wrong or missing caller ID on outbound calls
The Webex Calling trunk setting Dual Identity Support decides the From and P-Asserted-Identity headers on outbound INVITEs to the trunk: when enabled the two can differ, and when disabled they are identical.
Checked 2026-09-25
With Dual Identity enabled, Webex Calling populates From and PAI (and both identity headers can be different).
