Search this list for "progress" or "progressinband", and look at the voip-
info wiki.

About 'r': There is a always the possiblity to introduce new 
bugs/regressions in newer Asterisk version; test two 1.4 versions and if 
you find a difference then consider to open a bug report.

In general: The 'r' option is very seldomly what you want to use, it 
presents the caller ringing even if the other side is busy/congested.
