IP phone 7942 showing incorrect time

shahzad.iqbal · ‎02-10-2010

Communication Manager Express is running in our environment. We have two models of IP phones 7942 and 7911. The existing phones are working properly but when I plug new IP phone 7942 it is showing incorrect time while new IP phone 7911 working fine. As time is critical in voice network and I need to solve this issue kindly help me. I have CME version 7.0.

Regards,

Shahzad

Hi Shahzad,

There are some good tips in this doc and the attached thread has excellent
time references from Paul @ Cisco;

Hope this helps!

PS: Keep in mind that the 3rd generation phones like the 7942 act differently

than the older 7911 phones when it comes to deriving the correct time
