[Reviewer: Mike] External I-CSCF

Mike,

Please can you review my changes to add (optional) external I-CSCF function to sprout?  This is simply a case of hooking in when completing originating processing and routing the call off to a configured SIP URI.  I've added UT to confirm that the I-CSCF is invoked for originating calls but is not invoked for terminating.  I've also tested live.
