Outgoing conversation: Invalid proxy address

A conversation could not be created because the provided Twilio proxy address for the Frontline user was invalid.

• The outgoing conversation callback returned an invalid Twilio proxy number or no number at all.

• Make sure that the proxy_address value returned from the Outgoing Conversation callback is present and properly formatted in E.164 format, including any channel prefixes if relevant.
  • Check out the docs on how to create outgoing conversations.
