Time on IP Phones are fast

[cparapally]

Hi,

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

Hi Rajesh,

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?
