> and then you can try to get some packet dump with tcpdump/wireshark
if am ssh into the server and run tcpdump not port 22. i get normal LAN traffic
until i make a call. then i get a ton of this. .8 is the phoneserver and .46 is
one of the phones. i haven't done wireshark because I haven't looked up
how to take the tcpdump and import it into wireshark.
