Ssending again because I'm not sure if the 1st one made it

Hello

I have an H.248 (MEGACO) trace capturing traffic between a controller and a remotelly located gateway.
The sniffer is located at the controller side and contains about 200.000 packets.

It looks like some of them are retransmissions.
Wireshark does not recognise the retransmission (no indication in the packet details) so the packet is displayed as normal.
The way to recognise it is that 2 frames sent within a few seconds interval are identical (also same transaction id).

I would like to count these retransmissions but I can find no obvious way through filtering or statistics excluding of course counting the packet one by one.

Any ideas anyone?

thanks
Manolis
