UCM630X Series User Manual
Version 1.0.11.10
Allows external numbers the option to get directed to the extension that last called
them.
For Example, User 2002 has dialed external number 061234575 but they were not
reachable, once they have received missed call notification on their phone, they
would mostly call back the number, if the option “Direct Callback” is enabled then
they will be directly bridged to user 2002 regardless of the configured inbound
destination.
