Hi,
Thanks for the detailed explanation. It's really useful.
I'm trying to automate this whole process. All tools except Ethereal (tcpdump, rtpdump, voiceage decoder) are command line tools that can be used in a batch/shell script.
How can I export rtp stream without using Ethereal, or from command line ?
is there a way ?
Thanks,
ilker

First you export the RTP data from within Ethereal like this:
1. Open Capture
2. Click on Analyze->Statistics->RTP Streams->Show All 3. Select the stream you want to export 4. Click 'Save As'
5. Then feed that file into rtpdump like the below example 'trace.rtp'.
Here is the command line:
rtpdump -F payload -f trace.rtp -o file.out
file.out will contain just the payload which can then be decoded.

Hi!
Some questions regarding tm:
How long does statefull transactions live inside openser? Is it correct
that wt_timer is the timeout for completed transactions, and
fr_inv_timer/fr_timer is for incomplete transactions?
What is a complete transaction in case of INVITE? With or without ACK?
openserctl shows 44 transactions although the box is idle since long time:
tm:inuse_transactions = 044
Are there really 44 transaction open or what does 044 mean?
How much memory does a transaction approximately need (no AVPs)?
thanks
klaus
Hi guys.
I'd like to hear about different methods of implementing cisco like
transtation rules in SER. I was thinking about AVPs, but still couldn't find
the ight way.
Is someone is doing it inside or outside ser, please shed a light on
this!. What i need is to stip some numbers, and then add some other
(variables) before proxying the calls.
Thanks in advance.
Hi all,
I want to know how OpenSER is able to identify the BYE that match a
dialog. what are the essential header needed for the BYE message?
I try to understand how work the acc module and what are the header
needed in the BYE for generate accounting.
My goal as i have wrote is to send a fake BYE to OpenSER and do
accounting.
In my test OpenSER correctly parse fake BYE and try to send the BYE to
the UA, but don't send accounting info maybe i missing something
essential for send acct.
My fake BYE have: Via, Record-Route with ftag, To to-tag, From from-tag,
Call-ID. i miss only the correct CSeq but i insert a custom CSeq like
9999.
Any hints pls?
:tele
Can anyone advise on the easiest way to know from which direction an INVITE
is coming (ie. From my user to the world, or From the world to my user)?
Thanks in advance.
Hi Norman!
I'Ve never had any problem with the default debian script (the one that
gets installed when compiling debian packages with "make deb".) on sarge.
Which debian are you using?
regards

hello,
I am new to SER, the thing is I want to route a call thru SER
without registering at SER. let me explain in more detail.........if there
SIP phones are running diffrent machine say A and B. SER is running on my
machine. if any one sip phone wants to call other sip phone, the call must
be registered.
i want to make this registartion feature off. that means call should be
routed thru SER but it wont be registered at SER.
please help me
Thnaking u,

Hi, Thanks for the message, I found libmysqlclient.so.10 in /usr/lib/mysql, tried creating a symbolic link to it in /usr/local/lib/ser/modules, that didnt work. Then I copied libmysqlclient.so.10 to /usr/local/lib/ser/modules as libmysqlclient.so.12, that didnt work either, I still get exactly the same error saying "ser: ERROR: load_module: could not open module </usr/local/lib/ser/modules/mysql.so>: libmysqlclient.so.12: cannot open shared object file: No such file or directory" I am sure the file does exist, still SER complains No such file or directory.... Isnt this very very strange? Anyother ideas?Thanks again! Cheers ^C _____________________________________________________________Hi,libmysqlclient.so.x exist under /usr/local/lib/mysql/ in FreeBSD. Ihave SER running on my FreeBSD 5.4 box now and I had this problembefore as well. What I did is just created a symbolic llink tolibmysqlcllient.so.10, named libmysqlclient.so.12 as in# cd /usr/local/lib/mysql# ln -s libmysqlclient.so.10 libmysqlclient.so.12Though some ppl might discourage such a practice, it works well for me.

Hi!
I tried to test openser's call setup performance.
Scenario: INVITE - 180 - 200
Server: 2 x P3 1266MHz
listen=UDP:...
children=100
I used SIPP for testing.
1. Although the config is rather simple (no DNS, no DB, no lookup) I
can't get more than 700 INVITE transactions per second. Shouldn't this
be higher (AFAIK ser powers the whole bay area on a handheld PC)?
2. With children = 100, I can see more than 200 threads and lots of unix
sockets opened, although no DB is used. Why?
3. openser core dumps when children=200
regards
klaus
