How To Trace A Call In Progress

by  MitelInMyBlood  Posted    (Edited  )
The RESOURCE command can be used to find out what trunk a specific call is on, but in order to use the resource command you first need to know the PLID (Physical Location ID) of the extension or trunk, so before we can continue we first need to know one of the PLIDs our subject call is on.

Likely we haven't a clue which trunk the call is on, but we generally know what extension is in use, so lets start by finding out the PLID of the extension.

Mitel complicated this a little bit for us on the 3300 with their use of virtual PLIDs, but if you know where to look you can find the PLID easily enough. Either the maintenance command LOCATE FEATURES EXTEN xxxx will give us the PLID or we can also find it in the CHANGE ATTRIBUTE ASSIGNMENT form.

Armed with the PLID, we can use the RESOURCE command in conjunction with the plid, as follows: "RESOURCE PLID" or in other words;

reso 1 3 1 15 1 <enter>

And get back the following response:
Code: 
Circuit: MC125AA IP Line at location  1  3  1 15  1                             
Call Process: 6 3E0                     Device Type: 5340 IP                    
Call State: Talking                     Party Type: Originator                  
Receive Link: 133   Channel: 16         Transmit Link: 133   Channel: 16        
                                                                                
>>>>> Other Party for Call Process 6 3E0                                        
Circuit: MC263BA DS1 Formatter at location  6  1  4  1  2                       
Call Process: 2 37C                     Device Type: DS1 Formatter              
Call State: Talking                     Party Type: Terminator                  
Receive Link:  23   Channel: 22         Transmit Link:  23   Channel: 22
As you can see we know that the call in question was originated by the PLID of our extension and is leaving the PBX on PRI 6-1-4-1 channel 2

The process works either way. If for example you had a trunk that had been tied up a long time you could see who was on it by using the resource command with the PLID of the trunk in question.
