What they are talking about is SIP URI dialling. Let say you have
extension 1000 the rings a phone on your system. With allowguest=yes I
would be allowed to dial SIP:/[email protected] and assuming the
context defined in your [General] section had access to exten 1000 I
would connect to that phone. With alloweguest=no my call would be rejected.
That does not mean that strangers can not call an IVR and get to your
1000 extension or even a DID that point right to it.
If you are going to allowguest=yes you need to take carfule note of your
contexts so as not to allow strangers access to parts of your dial plan
that have, lets say long distance routes.
Does that help?
Thanks!!

Hello
I don't understand how I should use the "allowguest" item: If set to
"yes", callers from the Net should authenticate, but then, how can I
allow strangers to call extensions in my system?
"allowguest
If set to no, this disallows guest SIP connections. The default is to
allow guest connections. SIP normally requires authentication, but you
can accept calls from users who do not support authentication (i.e.,
do not have a secret field defined).Certain SIP appliances (such as
the Cisco Call Manager v4.1) do not support authentication, so they
will not be able to connect if you set allowguest=no:
allowguest=no|yes"

Thank you.
