[asterisk-users] Help me understand these log messages

[Yves A.]

... an anonyous (not registerted) sip user from 188.161.238.232 was 
trying to initiate a call to
9725955 and so on...
you could enable sip tracing to get more information.

maybe you should change the 'allowguest' option in sip.conf..?

regards,
yves
