DESCRIPTION
Enables/Disables sending Supported:100Rel and by this whether early-dialogs by PRACK will be offered.

Enabling this could be useful if the opposite wants to play music/ring-back-tone or announcements before the call is connected.

  • On -> Supported:100Rel will be send (and opposite could initiate Early-Dialog by sending Required:100Rel)
  • Off -> Supported:100Rel wont be send (and opposite gets no chance to initiate Early-Dialog)



Note:This does not influences whether the phone itself will send Required:100Rel if from opposite Supported:100Rel is signaled and by this initiating a early-dialog. This behavior is influenced by require_prack -> see Settings/require_prack.

VALIDVALUE
<on>, <off>
