Very little as the amount of data being captured is quite small. We have
it running on our production servers which routinely handle a couple of
hundred concurrent calls.
This is the script we use to start off the capture. It uses rolling
capture files so we will always have the last X number of capture logs.
It works very well and we have a custom system which enables us to
search for calls and request traces for them for when we have to
diagnose problems.
#!/bin/bash
cd /var/lib/asterisk/siptraces
DATE=`date +%Y%m%d%H%M%S`
TRACEFILE=/var/lib/asterisk/siptraces/$DATE-siptrace.pcap
nohup /usr/sbin/tcpdump -p -i eth0 -s 0 port 5060 -w $TRACEFILE -C 10 -W

You're right, seems like a nice way to debug. Regarding that, how
would the impact be affected running it on asterisk box? I guess only
port 5060 is not too bad

Hi folks,
We've been having a weird issue... It is happening more often in
the last few months...
Most inbound calls, we have in our dialplan before Queue():
Set(CALLERID(name)=${PARTNER}:0:${CALLERID(num)}:${UNIQUEID}:${CHANNEL});
So when the call rings a member, softphone will show this string ....
The issue is that sometimes the string showing in the softphone
is not the same. Its a string from a past call, in the latest
case I've seen, from about 40 days ago!!
User took a screenshot, I've searched for that uniqueid showing
in softphone in cdr, and that string was valid for a different
call 40 days ago!!
I searched full log, and Set() sets the correct string... I can't
figure why softphone shows a string from a past call !!
:(
Any hints ?
I would leave tcpdump running capturing port 5060 so you can load
it onto wireshark and have a look at the sip headers. That will
tell you if the SIP is incorrect or if its a problem with the client.
