Hi Sudeep, Goto "call routing

Hi Sudeep,


  1. Goto "call routing" > "class of control" > "partition"
  2. select the partition which is associated to the Device profile ( roaming profile )
  3. change the Timezone in this partition and apply config.

It will fix your problem.

my ip communicator. when login or logout to phone my time on phone is correct but my problem is

since on the system time shows as UTC my users will auto logout as per UTC timezone. i have set user logout policy after 8 hours and their is a gap of more than 5 hours between UTC and GMT time slot.

Hi, the 'Extension


 the 'Extension Information' shows the time in UTC format.

 Although its in UTC format, your users will auto logout after 8 hours of their login, in other words, if your users shift are between 08:00 AM and 05:00 PM (IST - +5:30 from UTC), then it will login on 01:30PM and auto logout on 10:30PM.

Hope this helps.
