If this is the case then the address you are pointing to at the pstn is incorrect. If you add the ntp server to the router and do show ntp status the router MUST be syncing with an external source or UCM will not sync. Furthermore a reboot is not required on UCM or ther router. Simply add the address to UCM and do utils ntp restart from cli. The key is that the ntp source the router is syncing with must be valid.
