Mitel Director NCC logs

Read Time:4 Minute, 38 Second

One of the things that have helped me throughout my struggles with Mitel/Shoretel is the NCC logs inside the shoreline data folder. These logs can be hard to read, and very aggravating. Let’s look at a log example.

Below is a table that explains each of the call letters at the beginning of the log.

Call LettersEvent NameWhat it does
C-CECall Creation EventCall Initiation
L-CELeg Create EventFollows a C-CE for every call setup. internal transfers (Blind Transfers)
L-IELeg Info EventFollows a C-CE, L-CE. Leg info provides information on other parties in the call.
C-SECall State EventState of call in progress, all parties. This includes RingBack, Offering, established, etc
LSELeg State EventFollows a C-SE to inform the leg state changes.
L-DELeg Destroy EventCall Teardown. The Leg is destroyed.
C-DECall Destroy EventThe call is destroyed by the user or system hung up.
G-MSTMedia State EventMedia stats for the terminated call leg. Every RTP stream also has a media state event.

Here are examples of what each part will look like.

Now let’s look at this example below and take it apart from a little. I’m no expert but I have gone through a few hundred of these logs.

I hope this is helpful. I’m no expert, but I do follow the logs to see where they lead me.
