Create a number masking session

You create a number masking session using the real phone numbers of the two parties that need to be connected. Plivo returns a virtual number from your account in response to the API request.

  • If one party makes a call to the virtual number, the call is connected to the other party.
  • The caller ID of the outbound call to the second party is the Plivo virtual number.

This method creates a session to anonymously connect two participants.
