Running the tcpdump Tool

Running under the command line, this common packet analyzer allows network
administrators to display TCP/IP and other packets transmitted or received over the IP
telephony network.
➢ To run tcpdump:
1. Access the phone via SSH and run the following commands:
cd /storage/emulated/0/
mkdir recording
cd recording/
tcpdump -w rtp.pcap
2. After running TCPDump, reproduce the issue.
3. Press Ctrl+C to stop TCPDump:
curl -T /storage/emulated/0/recording/rtp.pcap tftp://host_ip/rtp.pcap

Activating DSP Recording

Network administrators can activate DSP recording using SSH protocol.
➢ To activate DSP recording using SSH protocol, type the following at the shell prompt:
setprop ac.dr_voice_enable true
setprop ac.dr_ipaddr <ip_address>
setprop ac.dr_port 50000
DSP recording can be activated on the fly without requiring the network administrator to
reset the phone.
