route the call to the info app to test out all the things you can use in the regex.

<action application="info"/>

anything you see that starts with variable_ is available as a variable
so variable_sip_from_domain: cool.com can be accessed as ${sip_from_domain}

There is for sure some stuff in there that will tell you.

Any variable is valid in the field attr of a condition

ex.

<condition field="${sip_from_domain}" expression="cool.com"/>

also you can use the function sofia_contact to do a regex on the contact addr of the registered user

${sofia_contact(1000@xyz.com)}

Much of this should be documented in the default configs in tree and on the wiki
