Hi,
The following link states that XNTP enables NTP client only and it cannot serve as Server, so you cannot synch TO it.
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a008009470f.shtml
I am running XNTP on all Call Manager servers and all subscribers are pointing AND successfuly synching with the publisher using XNTP.
I had also tested it by pointing Cisco router to the publisher as NTP server and it all works.
So, is this document inaccurate?
Thanks,
David
