I have been working on sip configuration to do qualify on the level of active calls , but so far no option to do that , and I haven't found any script useful to do just that , if not if there is any command in asterisk CLI to accomplish this task

Dears,
I have made it by writing a custom script that gets the active calls and take the call-id from there and send an option message every 5 seconds
