Hi, when using pjsua from Python, the library always prints the log-messages for pjsua.Lib() to stdout: >>> import pjsua >>> lib = pjsua.Lib() 16:42:34.584 os_core_unix.c !pjlib 2.5.5 for POSIX initialized 16:42:34.584 sip_endpoint.c .Creating endpoint instance... 16:42:34.584 pjlib .select() I/O Queue created (0x2018100) 16:42:34.584 sip_endpoint.c .Module "mod-msg-print" registered 16:42:34.584 sip_transport. .Transport manager created. 16:42:34.584 pjsua_core.c .PJSUA state changed: NULL --> CREATED That's ugly. Is there a way to prevent this, so that these log-messages also use the log-callback? thanks, Roland
