Once call duration limit is enabled, it will set the maximum duration of
call-blocking.
User can customize the maximum call duration (in seconds) that is allowed
for the outbound call. By default, this value is set to 0 means there is no
limit for the call duration.
This option will give caller warning when call duration is approaching to its
limit. If the warning time is set to 'y', the warning tone will be played to
caller when y seconds is left to end the call by UCM.
Once this option is set to 'z', it will repeatedly warning caller every z
seconds after the first warning.
Select privilege level for the outbound rule.
Internal: The lowest level required. All users can use this rule.

Local: Users with Local, National, or International level are allowed to
use this rule.

National: Users with National or International level are allowed to use
this rule.

International: The highest level required. Only users with international
level can use this rule.
The default setting is "Disable". Please be aware of the potential security
risks when using "Internal" level, which means all users can use this
outbound rule to dial out from the trunk.
When enabled, users could specify extensions allowed to use this
outbound route. "Privilege Level" is automatically disabled if using "Enable
Filter on Source Caller ID".
The following two methods can be used at the same time to define the
extensions as the source caller ID.
3. Select available extensions/extension groups from the left to the right.
This allows users to specify arbitrary single extensions available in the
PBX.
4. Custom Dynamic Route: define the pattern for the source caller ID.
This allows users to define extension range instead of selecting them
one by one.

All patterns are prefixed with the "_".

Special characters:
X: Any Digit from 0-9.
Z: Any Digit from 1-9.
N: Any Digit from 2-9.
