That worked, however, SER doesn't answer any sign-ins. There has to
something very easy here where a person signed-in isn't seeing anyone else
signed in. Any thoughts?

If you are starting ser at boot, don't set dont_fork=1 in the cfg. file.
This will stop ser from becoming a daemon and detaching and it will block
your booting process (on most distributions).
dont_fork is only for debugging, which means manually starting ser, from
a terminal.

Hi!
I have tried ser + nathelper + rtpproxy:
Following configuration:
Clients inside NAT: IP 192.168.0.x
Windows Messenger
NAT-Box: old mandrake linux (2.2 kernel) + ser (cvs from 7.7.03) + rtpproxy
(08-Jul-2003).
local interface: 192.168.0.1
global interface: mydomain.dyndns.org
ser and the rtpproxy are running. The clients register at ser
(sip:klaus@mydomain.dyndns.org).
1. I can receive incoming calls (signaling and rtp works fine). But in the
outgoing messages, ser adds a via header with the local IP address
(192.168.0.1) instead of the global IP address.
How can I configure this in ser.cfg?
2. The rtpproxy starts relaying after RTP packets from both sides are
received. That causes problems if the clients use silence suppression (like
Messenger):
I call my friend (I am quiet, so no RTP packets will be sent).... the friend
answers: "Hello!" ... both the rtpproxy doesn't relay, so I don't answer
.... my friend again "HELLO" ... the rtpproxy still doesn'relay, so I don't
answer..... and so on.
So, I suggest the rtpproxy should start relaying immediately.
regards,
Klaus

Hello all !
I would like to change the time zone in time column in acc table
in database ser. Nowaydays it is a UTC(GMT)
Field timestamp in this same table is in my local zone CET
Is some way to change it ? Some parameter in modules
included in ser.cfg (acc.so) ?
Greetings
Andrzej Radke
I have 0.8.11pre29 installed on Redhat 8.0. Also have MySQL installed and
working, so my users have been declared "persistant".
I can sign-in, but cannot see any of my contacts that are signed-in. If I
go to the server, I can see the list of those signed-in. I tried to change
the ser.cfg file for debugging, but then SER won't start up, and the server
hangs at "Starting SER". I can't go any further at the console, I have ssh
in and kill then process then reboot.

Andrei,
thanks very much! I have now taken Jiri's advice and use the textops
package to add the header.
However, in the package, I'm calling append_hf with the message and a
char* which is the new header. From the look of it, it seems that
append_hf should call str_fixup for the char*. This does not seem to
happen. I included some debug messages and str_fixup is not called.
Thus, the length of the string in append_hf_helper is just garbage. I
have included an explicit call to str_fixup in append_hf and then
everything works fine. I'm not sure how exactly the cmd_export_t
structure is working - for append_hf it lists str_fixup.
Thanks again for your help!

I would like to get more information on accounting with SER.
Ok, I followed the documentation about accounting but it doesn't give enough information about how to retrieve the accounting information. It just says that Reports are by DEFAULT sent to the syslog facility. Where is that syslog? How do I retreive that information? Is it possible to put that information in the MySQL database? How?
That is by DEFAULT; so, is it possible to change that default location?
Some gurus will realize how NEWBIE I am in the Linux World.
Please help me.
Thanks,

While trying to use the command for adding an alias, the computer tells me that the aliases table was not found.
But I can see the aliases table in the database.
What do you think might be wrong?
Thanks,
