  Registrar is a pice of code that processes REGISTER messages and
  stores/retrieves data to/from user location database.

  Usrloc is a module that implements the location database.

  Only memory is used for lookups.

  Depends on your configuration. PA can either check registrar or jabber
  gateway. The status is not sent in SDP, but in the body of NOTIFY
  messages. It's an XML document.

  There is a problem with pa in the current version, we are working
  on a fix.

  Please describe the troubles more thoroughly.

> and i noticed something, when the caller hangs up while the other phone's still ringing, i could see the "bye" from messenger but ser doesn't proxy it to the other party. so the other phone continues to ring. is this because ser expects a "cancel" rather than a "bye"?

  It should forward the BYE. Check it with ngrep.
