All the IP phones in one of my sites are showing 5/6 minutes faster than the normal time.
Could you please let me know where I can exactly tune up the time?
Thanks in advance.
What type of call manager are you running CME or CCM?
You can synchronize using NTP
Here it is for CCM
I am using CCM 4.x
The time difference between CCM server and all IP phones are 6 minutes.
How can I see the same time on server and all IP phones?
