  • On -> Supported:100Rel will be send (and opposite could initiate Early-Dialog by sending Required:100Rel)h1. 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.
