and the pound sign #.
Description Use the area-id command to configure the area ID of the voice GW.
Use the undo area-id command to remove the specified area ID.
By default, no area ID is configured.
The voice area ID is set in VoIP entity view and will be automatically added to the
beginning of called numbers when making calls. If SIP is specified for routing, this
command is invalid.
Related command: match-template, address, and entity.

Parameter time-threshold: Number of busy tone periods for detection, in the range of 2 to
12. A bigger value means a longer busy tone detection time.
Description Use the
busytone-t-th command to configure the number of busy tone periods
for detection.
Use the
undo busytone-t-th command to restore the default.
By default, the number of busy tone periods for detection is 2.
You can enable the busy tone detection optionally. Under particular situations,
however, the actual busy tone data cannot exactly match the busy tone
parameters configured for the system. If there is a big difference, the busy tone
may not be detected correctly, resulting in on-hook failures or wrong on-hooks. By
adjusting the time threshold of busy tone detection, you make the busy tone
detection more precise.
Note that before you configure a threshold of busy tone detection, you must test it
fully making sure that on-hook operation can be done properly.
