enabled between the UCM6100 and the peer UCM6100,
the remote extensions will be listed under "Available Extensions". If not,
monitored in the event list.
Valid format: 5000,5001,9000
Remote extension monitoring works on the UCM6100 via event list BLF, among Peer SIP trunks or
Register SIP trunks (register to each other). Therefore, please properly configure SIP trunks on the
UCM6100 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 UCM6100 and remote extensions are added to the list, the UCM6100
will send out SIP SUBSCIRBE to the remote UCM6100 to obtain the remote extension status. When the
SIP end points registers and subscribes to the local UCM6100 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 local extensions, remote
extensions, subscribers for each event list. Users can also select the remote event URI to check the
subscribers' details.
