If you want record of calls - check Monitor, if you want listen online - then there is application ChanSpy. If you want to know online status - AMI provides very nice options, and with some filter you could know when extension is called and who call it etc.
Nice… at this time im recording the calls; and i want to filter this recordings, for sample… record all calls from ext200 but if this one calls to ext300, do not record this single call…
can i do this with Monitor, or i need another app??
You need some modifications in dialplan or using AGI - main idea StartMonitor if call is not to ext200, else direct dial.
You can safely use StopMonitor without starting.
