    abstract =  {This document analyzes the interoperability problems surrounding the call-completion feature that allows a callee to put a caller's request into a queue by which the caller can be notified to call back the callee at later time. This document analyzes how different solutions inter-operate and tries to make recommendation on how to best meet this requirement},
