machine connected in between the two routers somehow. Since you didn’t
give any information about how the two routers are connected to each other, I
can only offer guesses on how you might accomplish that. If they are connected
straight to each other with Ethernet, then put a hub (or a switch with a SPAN
port) in between or use an Ethernet tap. If they are connected to each other
with something other than direct Ethernet, then I’m guessing you’re
SOL but at the very least you would need to provide us with information about
the connection.</span></p>

I have two routers .On 1 router i have router---switch--phone(1000)<br>
<br>
second router router----phone(3000)<br>
<br>
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.<br>
<br>
In wireshark i can see information happening on first router but i cannot see
any information about second router nor the phone.<br>
