If I understand you correctly you want to capture voice packets. When I was training \
someone on this - here are the steps I used.
1. I picked an IP phone to trace . Example I have extension 2224 on my \
desk. 2. I found out what port that was going to on our switch
3. You have 2 choices
A. You can mirror the port and hook ethereal to the mirrored \
port.
B . disconnected the port and put a hub in between and hook your \
analyzer up. 4. I first wanted to show steps phone would go to to boot.
I started Ethereal and unplugged phone and caught a sniff of what was \
happening.
5. I started another trace and made a phone call. Captured that call
6. Went to statistics and looked for jitter or other impairments
To listen to actual voice traffic I don't believe ethereal does that. I could be \
wrong -it wouldn't be the first time nor would it be the last. Is the reason for \
listening to listen for impairments? What is the plan you have?

Subject: [Ethereal-users] I need to help
I am a university student and I have a project on network analysis. I don't know how \
and where to start the project from. my project is concept of network analysis and \
the only, I want to capture data voice packets which goes through network. besides \
that I want to merge and edit them after that I will listen to them by making a \
program.
