A SIP Trace is the most powerful tool to analyze all SIP related network traffic (application
layer) that enters and leaves the phone's built-in Ethernet switch.
To perform a SIP trace:
1. Open the SIP Trace page and click Clear.
2. Perform the scenario which caused the unexpected behavior in a basic environment.
You can filter the displayed SIP messages via the Advanced > Network page setting
SIP Trace for REGISTER/SUBSCRIBE/NOTIFY. You may enable the filter if the
problem is not assumed to be related to Registration (REGISTER) or BLF Function
(SUBSCRIBE and NOTIFY) but call issues.
3. In the SIP Trace page, click Reload.
4. Select and copy the content of the page and paste it into a plain text document (such
as Notepad).
5. Save the textfile and name it in order to be identified easily. Attach the file to your
support request.
