Packet Capture - T4x w/OpenVPN
Hi,

Yealink SIP-T42S F/W: 66.84.0.125

When I do a packet capture via the phone GUI on a T42S phone utilizing openvpn it isn't capturing the decrypted traffic. It appears that pcap captures are running on the ethernet interface instead of the openvpn network interface.

Is there a setting that can be tweaked so I can grab this traffic?

Failing that, is there a way I can ssh or telnet into the phone and use tcpdump manually to grab it?

I'm trying to diagnose intermittent RTP issues.
