Hi all

I trying to call conference via sched_api but can't find any way to send flags to the conference
${sched_api +1 none conference $1-${domain} play file_string://${namefile} }

so 

${sched_api +1 none conference $1-${domain}+${flags} play file_string://${namefile} }

cant find conference with searched name

${sched_api +1 none conference $1-${domain} ${flags} play file_string://${namefile}}

Says that ${flags} is can not be used here

So is here any way to call conference with flags?
