The capture begins when the application begins.Īlso, traceSM’s capture buffer is limited in size to 10,000 packets and once that limit is reached, it stops collecting and displaying packets. You cannot start traceSM and expect to see SIP packets that were sent prior to launching the tool. It’s important to know that traceSM is a real-time capture tool. Switch between SIP calls and display mode Switch between displaying RTP simulation or not Switch between displaying Names or IPs in the column headers Write the displayed (filtered) packets to a new file The SIP URI is highlighted in red, the SIP fields in blue and the content (e.g: SDP, xml) in green.ĭisplay the Filter window to view/change filters Move between different columns (IPs) when they don’t fit in the screenĭisplay the SIP/SM details.

However, Avaya advises against running multiple instance of traceSM in a production environment as it may cause performance problems. To invoke multiple instances, it must be run with the -m option. Personally, I use the TuTTy program, but you can accomplish the same thing with vanilla PuTTY.īy default, only one traceSM can be running on a Session Manager at any given time. To run traceSM you need to Telnet into an active Session Manager. Second, traceSM allows you to see Avaya specific data such as Personal Profile Manager (PPM) messages and Session Manager call flows. First off, it allows you to view SIP messages even if they have been encrypted with TLS. While not as powerful or versatile as wireshark, traceSM is absolutely essential when it comes to working with Avaya SIP. TraceSM is an interactive perl script that allows an administrator to capture, view, and save call processing activity on a Session Manager. Understanding Avaya’s Personal Profile Manager (PPM) The Steps Involved in Booting an Avaya SIP Telephone These two articles may help you better understand Avaya SIP and subsequently, traceSM. Therefore, I am documenting what I know in the hope that the next person who endeavors a search will find this blog article and have something to work with. I have also asked people who work with traceSM on a regular basis if they’ve found anything useful and I always come up empty. I would love to be proved inept in my efforts, but I’ve searched through every Session Manager document I can find.

As hard as I’ve tried, I have yet to find a halfway decent manual that explains how to use what is perhaps the most important Session Manager debugging tool. Case in point is the Avaya utility, traceSM.
