Hello.
Recently I've been fighting with SER running on local IP, which is
statically mapped to public one via NAT/firewall.
The problem was in SER putting local IP into Record-route field.
Therefore, a public client (X-lite) was trying to send BYE message to
this local IP. I used record_route_preset("<SER public IP>") in place
of record_route() to solve the problem.
Does someone have any comments on the method? Are there any other
solutions, (despite the obvious one to put SER into public
Internet)?
Usage of record_route_preset() is not recommended by the docs.
Wouldn't it brake anything?
...Bye..Dmitry.
hello friends,

Hallo,
In order to listen for the messages from SER , should I write a module in DISC Client?

Hi, i compiled some of the tools included in the /test directory of the source CVS of SER. I want test the performace of SER in my server and look at the udp_flood.c program included, this generate a flood of SIP messages to the server. My question is how interpret the results.
If i send for example a flood with INVITE request for non-existent user to my SER and see how much SER respond to this flood in a time period, i supose that this is the Call Per Second supported by SER ?
Ex:
# flood SER with 100 request in one second
./udp_flood -f invite00.sip -d 192.168.1.1 -p 5060 -s 1000000 -t 100 -v -c 100
# SER make a log(1,"PROC_OK") for each invite processed
...
# At the end of udp_flood execution + some seconds i make
grep "PROC_OK" /var/log/ser.log | wc -l
Now, after this if i can see 100 at result of wc -l i supose at least 100 INVITE per second is supported for my SER ???
Thanks !
Usage: udp_flood -f file -d address -p port -c count [-v]
Options:
-f file file with the content of the udp packet (max 65k)
-d address destination address
-p port destination port
-c count number of packets to be sent
-s usec microseconds to sleep before sending "throttle" packets
-t throttle number of packets to send before sleeping
-v increase verbosity level
-V version number
-h this help message
I want to download the MySQL module for my SER.
But there is nothing to download under that module.
So where can I get the module and installation guide for MySQL module.
Also can I work ahead and use SER w/o MySQL. If yes how can I do that
please provide me with the info.
Thanks

Are there any config entries required when clients will need to connect
using STUN ?
Could the configs for the Nathelper module, taken from the examples, be
interfering with clients using STUN ?
