callmanager and NTP

antonyice1

Hai guys,

we are planning to implement an ip telephony network with callmanager 6.x.Could some body tell me how to synchronise the callmanager 6.1 with the NTP server.

Also i would like to know what "Cisco Unified Communications Operating System Administration"
and what is a "Cisco Unified Presence Server".

You configure it when you configure your first node. If you didn't configure one there, you can use the CLI later - utils ntp config

Cisco recommends using an external NTP server that is stratum 9 or higher (1 - 9). The other nodes in a cluster get their time from the first node.

Cisco Unified Presence 6.0 datasheet

As for "Cisco Unified Communications Operating System Administration" -- here's the link to the guide.
Cisco Unified Communications Operating System Administration Guide for Cisco Unified Presence Release 6.0(1)

But it could also be a Class -- UCSAE (Cisco Unified Communications System Administration/Engineer).

Or it could be the Graphical User Interface (GUI) you log into.
