NOTE: If this is a capture of a connection between a phone system and a remote VoIP phone, simultaneous real-time captures from both ends will be required for troubleshooting.ģ.

A Hub cannot be used because the VoIP daughterboard requires a full duplex 100/1000 Ethernet connection.If this is a capture of a connection between a phone system and a VoIP phone, simultaneous real-time captures from both ends will be required for troubleshooting.A managed switch capable of port mirroring.Preferably a laptop with a 10/100 or 10/100/1000 Ethernet interface card.Half Duplex connections are not supported.NEC SL2100 KSU or NEC SL1100 KSU with VoIP daughterboard Card.This is a must-read for installers working with or troubleshooting VoIP issues. If you want to capture the traffic of a specific app, then tap on the ‘Android’ icon in the upper navigation bar and select the app you want to log or monitor.Wireshark allows you to capture and analyze VoIP network traffic and packet data from the NEC SL2100 and SL1100. By default, Debug Proxy will capture traffic from all apps. On the main screen, tap on the ‘Play’ button appearing in the center-right corner of the screen to start capturing traffic. Install if you want to decrypt SSL traffic. Just like before, you will be prompted to install an SSL certificate. Other than that, Debug Proxy also gives access to other tools that let you do throttle bandwidth, HTTP response and test latency as well as a network security for MITM attack vulnerabilities, web debugging, SSL monitoring, and more. What’s good about Debug Proxy is that its user interface is very intuitive and captures all packets in native code which makes it pretty fast and responsive.
