	Choose the realm challenge key. Default is auto_to if not set. 
	
	auto_from  - uses the from field as the value for the sip realm.
	auto_to    - uses the to field as the value for the sip realm.
	<anyvalue> - you can input any value to use for the sip realm.

	If you want URL dialing to work you'll want to set this to auto_from.
	
	If you use any other value besides auto_to or auto_from you'll loose
	the ability to do multiple domains.
	
	Note: comment out to restore the behavior before 2008-09-29
