Packets in different VLANS flagged as duplicated Packets in RTP Stream Analysis

Hi Everyone,

I am running Dumpcap as a service.

My users have told me that when they select a packet capture then select
Telephony - RTP - Show all Streams that it indicates packets are being
duplicated (negative packet loss).

For the packets being duplicated (negative packet loss), I discovered that
there are in fact 2 packets being seen by Wireshark with the same SRC/DST
IP Addresses and the same ID number BUT different VLANS tags.

Is this an error in Wireshark that should be fixed or is there some way to
configure Wireshark to look at the VLAN tag as well as the ID number before
determining a packet is duplicated?

Thanx alot!

John
