   [JRE] Does it necessarily need to wait for receipt of recall
   notification? Would there be any advantage in suspending as soon as the
   CC agent goes busy?

I think we would get better performance if the agent suspended
immediately when the caller became not-available.  The cost would be
that the agents would do more suspend/resume operations.  IIRC, SS7
also has the caller suspend its CC request immediately upon becoming
busy.

   [JRE] This is rather intangible. What would the consequences be? If no
   real consequences, this method would appear to have no disadvantages. Or
   are there disadvantages concerning place in queue, timeouts, etc.?

I think the disadvantage is better phrased "no separate suspend-resume
operation", which implies the disadvantages you mention:  caller does
not maintain its place in the queue, timeouts become difficult to
implement.
