Description

Time in milliseconds until the phone plays the internal ringer after early media announcement is finished. Since 10.1.150, this fallback is only possible when rtp_early_media_playback is set to preferred.
Example:

<--- INVITE (outgoing phone call)
---> 180 Ringing (phone plays internal ringtone)
...
---> 183 Progress + SDP (phone plays the incoming early media
                         instead of internal ringtone)
...
---> 180 Ringing (if early media is disrupted for x seconds
                  the phone will play the internal ringtone again)
and so on
