[Freeswitch-users] Ringtone on multiple destinations

Hello! I have a question about ringback-tone when calling multiple destinations. When i call a single directory-user, i get a proper ringback-tone - but when i add a second user to the bridge-command, there's no more ringback-tone. This is not about early-media - the phones only send 180 Ringing and the ringtone is provided by FS. Shouldn't FS send a ringback-tone as soon as the first phone answers with 180? Or is this behaviour just as intended? I've attached sip-traces of both situations plus the respective extension. Best regards Christian
