Participant


A Participant is a single individual communicating in a Session. There is a limit of two Participants per Session.

You can create a Proxy Participant in two ways:

  1. By specifying the private Phone Number of the Participant (Identifier) and relying on Proxy to select an appropriate Phone Number from the Proxy Number pool. The Proxy Number returned (Proxy Identifier) is the Phone Number that the Participant should call to reach the other party.
  2. By specifying both the Identifier and the Proxy Identifier. In this case, Proxy will attempt to use the Twilio Phone Number provided. Note: The Twilio Phone Number specified must already be added to the Proxy Number pool in order to be accepted.
