Hi.
Has anyone ever found a case where the successful dissection of one  
protocol depends on what was negotiated in another protocol?
Yes, this is done for RTP traffic, which is set up via H.245 or SIP/SDP.
I guess my question comes down to: how can we store the information  
from dissection of one protocol so that it can be used to dissect  
another protocol, while still following wireshark's dev guidelines.
Have a look at rtp_add_address (in packet-rtp.c), which is called from 
packet-sdp.c and packet-h245.c.
