; SIP Configuration example for Asterisk
;
; Note: Please read the security documentation for Asterisk in order to
;       understand the risks of installing Asterisk with the sample
;       configuration. If your Asterisk is installed on a public
;       IP address connected to the Internet, you will want to learn
;       about the various security settings BEFORE you start
;       Asterisk.
;
;       Especially note the following settings:
;               - allowguest (default enabled)
;               - permit/deny/acl - IP address filters
;               - contactpermit/contactdeny/contactacl - IP address filters
for registrations
;               - context - Which set of services you offer various users
;

In other words: allowguest = yes, is the default.
But in trunk the context for guest is [public], yours started in the
[default] context
