In the course „Multimedia Communication“ the task was to record a video phone call between two computers using SIP in a group of two.

Part one was to first test the call with the Linux Linphone, then establish a call by implementing the requests INVITE, ACK, BY and REGISTER with SIP according to the signal flow and monitoring the traffic with Wireshark. Part two consisted of building a SPIT generator and sending voice and video content advertisting a fictive product.
