SX20 is registered with CUCM. mode of SX20 is CUCM. CUCM is pointed to NTP server. IPPhones are showing correct time but not SX20. ntp is auto for SX20 in web configuration.
when I entered IP addresss for ntp server time become ok.
So question is why SX20 not gettting time from CUCM as like IPPhones. why we need to add the ntp server ip manually even in auto mode? so what is the difference between auto and manual then?
Or should we off the NTP mode to off when registered with CUCM.
Any body can explain this?
