[cisco-voip] how to take wireshark trace between two routers.

[anand]

Hi

I have two routers .On 1 router i have router---switch--phone(1000)

second router   router----phone(3000)

i want take wireshark trace.I was able to take the trace when i called from
1000-3000 by connecting the pc to the switch.

In wireshark i can see information happening on first router but i cannot
see any information about second router nor the phone.

My question is how to see the packets between the routers using wireshark
trace.

thanks,
anand.
