[Freeswitch-users] Strange Performance when using as SBC

Hi Ken,
1) I'd like to use FS to hide topology, so bypass media is not possible
2) done
3) done
4) not used
5) i'm using this ins switch.xml -> <param name="loglevel"
value="info"/>, if you think an other log level is more suitable.
Regarding logging, I can see in console and in the freeswitch.log that
there is still a lot of NOTICE logging, see below:

2009-02-02 08:33:56 [WARNING] mod_sofia.c:740 sofia_read_frame()
Changing codec ptime to 30. I bet you have a linksys/sipura =D
Do you have any idea where I can switch off this kind of logging. I
thought it should be in /dialplan/internal.xml, but I see that in
internal.xml -> <param name="debug" value="0"/>
thanks a lot for your suggestion.
regards,
rod
