Ankit,
You don't want to use GUI when you are doing massive captures, you can
use command line to do this.
One catch is that ethereal has 2GB limit to the size of file it can
capture into. So you need to use ring buffer feature as shown below if
ethereal to do this. It will make 10 files of 2GB and then wrap around.
tethereal -i eth2 -a filesize:2097152 -b 10 -f "udp" -F libpcap -w
/etherdump/eth2SIP.cap 2>/dev/NULL &
Also ethereal as Andrew as suggested needs to be run on a separate
machine by using port mirroring. Only be careful if you don't do this
correctly, you will capture duplicate packets - one which Nextone sends
and one which destination receives.
Hope this helps
Deepak

Hi Ankit,
SPAN is a feature of cisco switches it has got nothing related to
Nextone, it's for switch port-monitoring purpose, in this case you have
to configure SPAN on your cisco switch and plug your laptop to that
particular port that you've mirrored to and turn on ethereal to capture
RTP.
Please refer to the following cisco article for more information:

iguration/guide/span.html
Thanks
