[Freeswitch-dev] Not seeing WARNING and ERROR messages in log

I am not seeing SWITCH_LOG_ERROR or SWITCH_LOG_WARNING msgs from sofia_presence.c in the log, though loglevel is set to "debug" and "debug-presence" is set to 10. I do see INFO, NOTICE, and DEBUG messages. Is there something else to set? or do messages at these levels go somewhere different? Carolyn
