[Asterisk-Dev] Helps needed for Tethereal and sip

[phu at bevertec.com]

Hi, kind huys:

I need to remotely trace sip infomation using Tethereal on Linux terminal.
The following command line can trace UDP infomation:

 tethereal -V host 192.168.221.56 and port 5060

How can I trace SIP/SDP information using Tethereal command line like:

13 10.513251   10.128.31.64  10.128.30.10 SIP/SDP  Request: INVITE
sip:7819110000 at 10.128.30.10, with session description
  14 10.516436   10.128.30.10  10.128.31.64 SIP      Status: 100 Trying
  16 13.042616   10.128.30.10  10.128.31.64 SIP/SDP  Status: 183 Session
Progress, with session description
 380 19.362790   10.128.30.10  10.128.31.64 SIP/SDP  Status: 200 OK, with
session description
 381 19.462364   10.128.31.64  10.128.30.10 SIP      Request: ACK
sip:7819110000 at 10.128.30.10:5060

Or any other convenient SIP tracing tools?

Kindly looking forward to your helps!
