I agree that of those 2 is the better choice, but there's a third choice: 3) Always configure all phones and gateways to use the sipXecs system(s) as their NTP server using the IP address of the server(s). Note that this works even when NTP connectivity outside the LAN is constrained in some way. _______________________________________________ sipx-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-dev Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-dev
