[cisco-voip] RTP packets in a VoIP network.

[Leo Zicovich]

Hello all,

I am working in a VoIP network and I have a question
using tethereal to get the RTP packets to saved them
in a file to be played later. 

I use cisco AS5400 with an IVR (just to do a transfer
in a  Bridge transfer mode. The IVR adds the callee to
the connection and remains in the connection for the
duration of the transferred call):  GW1/2 --> IVR -->
GW1/2, and I am trying to use tethereal command line
on the IVR, but I get only the UDP/RTP packet’s for
the first connection (GW1 --> IVR), as soon as the
transfer is done (IVR --> GW1/2) and the communication
established, nothing is captured. was it enough clear?
I hope so.

Anyone know why is it happening? And how can I get all
the communication UDP/RTP packet´s?

Many thank in advance

regards,

Leo
