[Serusers] problem with ngrep utility

[Timur Elzhov]

Dear SER experts,

I'd like to capture the 'REGISTER' messages with 'ngrep' utilty.
I use ngrep from the Debian distribution, with version

  # ngrep -V
  ngrep: V1.43, $Revision: 1.66 $

So, I launch ngrep and then launch "X-Lite" client on the another
Windows platform. X-Lite said that it is successfully logged in,
however "ngrep" waiting meanwhile on SIP server ..

  # ngrep REGISTER port 5060
  interface: eth0 (159.93.16.0/255.255.240.0)
  filter: ip and ( port 5060 )
  match: REGISTER
  exit
  258 received, 0 dropped

.. trapped nothing. Where am I mistaken?

Much thanks.
