Asterisk 如何在接听电话后执行星号应用程序

我想在分机应答呼叫后执行此操作

exten => 2001,1,TrySystem(echo 'Call from ${CALLERID(name)} at
${CALLERID(number)} ${&DIALSTATUS}received
${STRFTIME(${EPOCH},,%l:%M:%S %p %Z on %A %B %e)}' >
/var/www/html/test/testfile.txt)

---

我该怎么做呢？

我想起来了，我用M打电话给马可，打电话申请拨号

exten => 2001,1,Answer()
exten => 2001,n,Dial(SIP/${EXTEN},,M(carl),)
exten => 2001,n,Hangup()
