[asterisk-users] Question about packet counts in voipmonitor

[Dovid Bender]

Mike,

Are you using port mirroring or is  VoipMonitor running on the same box? If
the latter I would run tcpdump and compare what VM says it has to what you
see in your wireshark dump. If you are sniffing via port mirroring your
switch maybe dropping packets (we had that when we tried to mirror 700 mbit
of traffic on a Juniper EX4200).
