With the Wireshark capture running, unplug the Biamp VoIP device from the switch for 5 seconds then plug back in.If this list does not appear there may be a problem with the port mirroring process described previously in this document.įigure 3 – Scrolling List of a Wireshark Trace You should now see a scrolling list of packets being displayed in the Wireshark window. Select Start on the bottom of the Capture Options Window to start the Wireshark Capture.Filtering the capture may exclude packets that are needed to solve the problem from the Wireshark trace. Ensure that the Capture Filter field is blank.Select the Network Interface Card of your computer that Wireshark should use to perform the capture.In the Capture pull down menu select Options.TLS must be temporarily disabled for the VoIP user account by the VoIP system admin while debugging is being performed, and re-enabled once all data has been collected. If TLS in being used Wireshark cannot display the encrypted data for debugging.
If this is the case, Wireshark can be used to help locate the point of failure.īiamp Tesira VoIP cards support the option of using TLS encryption. Possible causes can include communications issues over the network or issues with the configuration of the Proxy Server. The registration process may be hindered by something beyond the VoIP card itself. If a Biamp VoIP device is placed on a VoIP Network, but not registering with the Proxy Server, determining the point of failure can be difficult using the Biamp software alone. A program called Wireshark is a free, open-source packet analyzer that is used for network troubleshooting and analysis. This document describes the process of performing a packet capture of a Biamp VoIP device communications on a VoIP network. Verifying the correct data was captured.Method 2 - Using a secondary Managed Switch.Performing a Wireshark trace of a Biamp VoIP device
