Reason/Cause codes in SDL

[brown3wab]

Hi, I'm trying to determine a reason for call disconnects we are experiencing.  In SDL logs, examples below, I'm seeing the following Reason/Cause codes, though I'm unable to find a reference to determine what they mean. We are using Call Manager 10.5 and the phone in question is a 7962 using SCCP.  Thank you for any direction you may be able to provide.

Ideally this needs to be investigated by looking at the exact call flow and protocols involved. By checking the signaling we can see which party/side is initiating the disconnect, the cause code 16 is a generic one.

Hi,

Below is the list of "Call Termination Cause Codes"

16	Normal call clearing

Also see below series which would help.

Thank you, KB.  Based on the document you shared would this be Reason= Call forward busy Cause= Normal Call Clearing?
