Caller ID on Cisco 2600 and 3600 Series Routers and Cisco MC3810 Multiservice Concentrators
Caller ID Overview
VC-813
Cisco IOS Voice, Video, and Fax Configuration Guide
Call Time Display
When caller-ID information is sent, the local time set on the router is transmitted with the station name
and number. If a call received on an FXO port is terminated on an FXS port, the calling time received
on the FXO port is replaced by the local time while transmitting caller ID to the FXS port. This is also
true for calls received from the network. The router should be configured to retrieve network time at boot
up from an NTP server in order to maintain the correct local time setting.
