Special Extensions
Remote extension monitoring works on the UCM6200 via event list BLF, among Peer SIP trunks or Register SIP
trunks (register to each other). Therefore, please properly configure SIP trunks on the UCM6200 first before
using remote BLF feature. Please note the SIP end points need support event list BLF in order to monitor remote
extensions.
When an event list is created on the UCM6200 and remote extensions are added to the list, the UCM6200 will
send out SIP SUBSCIRBE to the remote UCM6200 to obtain the remote extension status. When the SIP end
points registers and subscribes to the local UCM6200 event list, it can obtain the remote extension status from
this event list. Once successfully configured, the event list page will show the status of total extension and
subscribers for each event list. Users can also select the event URI to check the monitored extension's status
and the subscribers' details.
enter the remote extensions under "Special Extensions" field.
Manually enter the remote extensions in the peer/register trunk to be monitored
in the event list.
