I think I had 1.2 release yesterday and I would bridge to user/1000 or user 1000@mydomain.com and/or do sofia_contact(1000) and all is fine.
However, since building on master in GIT last night: FreeSWITCH Version 1.3.0+git~20120828T230559Z~f1d201f03b (1.3.0; git at commit f1d201f03b on Tue, 28 Aug 2012 23:05:59 Z)

They return not registered. I have to do sofia_contact internal/1000. I'm not sure how to use user/ I replaced it with ${sofia_contact(internal/1000)}.
Was this an intentional change?
Is there some list of breaking changes somewhere?
