Skinny Client Control Protocol, or SCCP, is a Cisco proprietary protocol to control endpoint devices. Lisa Bock demonstrates how to decode a stream as RTP, so the streams can be played back in Wireshark.
- [Instructor] Skinny Client Control Protocol…is a Cisco proprietary protocol,…and it's used to control Cisco IP phones…and other Cisco endpoint devices.…Skinny is similar to Session Initiation Protocol and H.323,…but many feel it's easier to troubleshoot than H.323.…We'll see that Skinny starts out and uses…port 2000, and then the connection then moves to RTP.…
We're going to take this into Wireshark.…I have a packet capture that was done in a lab,…so here we can see some of the conversation…over here on the right-hand side.…MediaPathEvent, OffHook, SetRinger, SetLamp,…and other dialogue, so different things…that are occurring, and the communication…that happens that causes the messages that are sent…to the call processing software.…
This then helps the device to take the action…that has been indicated.…When we take a look at this,…we'll see that we know that RTP is being used,…but it doesn't quite decode it as RTP.…Let's go to statistics in Flow Graph.…In the beginning, we see some just basic information…about some commands that are sent.…
