  • Create a call link for other people with Signal to join.
  • The creator of a call link can choose approval settings for who can join the call.
  • The same link can be used for multiple calls.
  • The creator of a link can also delete it at any time.
  • Links expire if they’ve been unused for 90 days.
  • Admins / call creator can choose approval settings

Call link creator permissions

  • If “Require admin approval" is selected
    • The first time anyone joins the call, they must be “approved”. While waiting, they will not receive anyone else’s audio or video, nor will others see their audio and video.
    • If the creator “denies” someone’s request to join the call twice, they are “blocked” for the remainder of the call.
    • Anyone who has previously been approved to join the call, or a previous call on the same call link, will be automatically approved the next time they request to join, unless they are later “removed” from the call.
  • If “Require admin approval” is not selected
    • Anybody can join the call. Anyone removed or blocked during the call will not be able to rejoin for the duration of the call..
