reverse minor sip registration regression

Browse Source 
A registration regression caused by a code tweak in (issue #14331)
and a bug fix in (issue #15539) caused some sip registration
config entries to be constructed incorrectly.  Origially
issue #14331 contained the code tweak as well as a bug fix, but since
the issue was reported as a tweak the bug fix portion was moved into
issue #15539.  Both the tweak and the bug fix contained minor incorrect
logic that resulted in some SIP registrations to fail.

(issue #14331)
(issue #15539)
