I have installed virtual machine, to make sure the system just have HMP + VoiceGuide + wireshark, no anti-virus application, i also turned off the firewall.
When i run IP Media Server Demo, wireshark can capture SIP packet. But when i turned off IP Media Server Demo, and start VoiceGuide Status Monitor, wireshark failed to capture. Please check .pcapng file attched.
Thank you for all your support.
