Hi . Is there a way to check specific phone registered on CUCM on active call or not ? RTMT shows only registered or not but not call status for phone. I remember was working on CO system 6 yrs ago was able to see phone call status also caller and called numbers, start time with nice GUI interface .
If you are just trying to see if a particular phone is on an active call, you can enable "Web Access" on the Phone Configuration page. Once that is done, you can click on the IP Address of the phone, and check the "Stream Status" on the Streaming Status section.
It is sad Cisco didn't implement such mechanism to monitor phone activity. You can't use RTMT for this case because with rtmt u need to know is it incoming call to that extension or outgoing, then u need to know what to monitor extension or whole DID .
