[Freeswitch-users] bridge: early media: call waiting

Hi I have been using early media fail-over while bridging the call to multiple endpoints. For example, this is taken from the FreeSWITCH cookbook and works fine for user_busy and destination_out_of_order. {ignore_early_media=true,originate_continue_on_timeout=true,call_timout=60,monitor_early_media_fail=user_busy:2:480+620!destination_out_of_order:2:1776.7} But, it does not work when the telco sends a "call waiting" frequency. What should be the option for call waiting? TIA. regards, Anita
