Packet Gain

I am trying to trouble shoot some issues and its not packet loss. The only thing I see wrong is we are getting lots of packet gain. What causes about a 30% packet gain?

Text output:

20 packets transmitted, 20 packets received, 0% packet loss
round-trip min/avg/max = 17/39.7/112 ms

I beleive this is effecting the users voip.

Thanks,
