When investigating a functional problem with the Sangoma SBC (appliance and/or software version), it is a good idea to check if a 'core' file was created around the time of issue.
To check if your SBC has created a 'core' file, open an SSH session to the SBC.
An SSH session can be created by using either of the two methods:
1. use a terminal program (such as 'putty' on a windows box) and use your log in credentials with the IP address of the SBC
2.use the SBC'swebSSH feature which is built into thewebgui.
*note, you must use httpsto use the webssh
If a 'core' file was created, it will be located in the /var/core directory.
To navigate to this directory simply type the following in your SSH session:
Now type 'ls -al' to see if any 'core' files are present. This will show you any core files plus the time the core file was created.
If the time of the core file was weeks or months before the time of the issue, it is most likely not of interestto your case which means you can stopreadign this wiki page :)
The following is a screenshot of an SBC that had a core file created on December 8 2015:
Now lets go ahead and open this 'core' file for details
