Twilio Changelog | Sep. 26, 2025
Added support of sending a Display Name for /Participants calls to SIP destinations
We have added support for designating a display name to be included in the From header for calls to SIP destinations initiated via the Conferences Participants subresource.
You can define a display name using the new callerDisplayName parameter. If callerDisplayName is included, the From SIP header will include that string as the display name.
For example, if you defined callerDisplayName = “Alice”, the From header sent to the SIP destination would include:
From: "Alice" <sip:+15551112222@sip.twilio.com>
