Tshark command to capture both SIP and RTP on media servers
This is useful if you don't know on which port SIP and UDP packetes comes from and can dump in pcap
tshark -i eth0 -w capture.pcap -f "(udp port sip) or (udp[1] & 1 != 1 && udp[3] & 1 != 1 && udp[8] & 0x80 == 0x80 && length < 250)"
-i : specify your interface, If not use "any" to capture on all interfaces
-w : file to save
TCPdump to capture SIP on specific port!
tcpdump -nqt -s 0 -A -i eth0 port 5060
Grep both SIP and UDP at same time.
tcpdump -n -i eth0 | grep 'SIP\|UDP'
