版本14727中的逻辑是，如果源字符串匹配匹配到结果，那么条件为false，但是这里仍有一个匹配结果，结果是1001。（这里的翻译是照字面翻译，小伙伴们，你们看懂了没？） Logic in revision 14727 if the source string matches the result then the condition was false however there was a match and it is 1001.
regex 1001|(^\d{4}$)|$1

uuid_simplify
This command directs FreeSWITCH to remove itself from the SIP signaling path if it can safely do so
Usage:
uuid_simplify
uuid_transfer
Transfers an existing call to a specific extension within a and . Dialplan may be "xml" or "directory".
Usage:
uuid_transfer [-bleg|-both] [] []
The optional first argument will allow you to transfer both parties (-both) or only the party to whom is talking.(-bleg)
NOTE: if the call has been bridged, and you want to transfer either sides of the call, then you will need to use (or the API equivalent). If it's not set, transfer doesn't really work as you'd expect, and leaves calls in limbo.
Record/Playback Commands
uuid_record
Record the audio associated with the given UUID into a file. The start command causes FreeSWITCH to start mixing all call legs together and saves the result as a file in the format that the file's extension dictates. (if available) The stop command will stop the recording and close the file. If media setup hasn't yet happened, the file will contain silent audio until media is available. Audio will be recorded for calls that are parked. The recording will continue through the bridged call. If the call is set to return to park after the bridge, the bug will remain on the call, but no audio is recorded until the call is bridged again. (TODO: What if media doesn't flow through FreeSWITCH? Will it re-INVITE first? Or do we just not get the audio in that case?)
Usage:
uuid_record [start|stop] []
Where limit is the max number of seconds to record.
If the path is not specified on start it will default to the channel variable "sound_prefix" or FreeSWITCH base_dir when the "sound_prefix" is empty.
You may also specify "all" for path when stop is used to remove all for this uuid
"stop" command must be followed by option.
[[Channel_Variables#Call_Recording_Related|See record's related variables]]
Limit Commands
[[Limit#API|limit_reset]]
Reset a limit backend.
[[Limit#API|limit_status]]
Retrieve status from a limit backend.
[[Limit#API|limit_usage]]
Retrieve usage for a given resource.
[[Limit#API|uuid_limit_release]]
Manually decrease a resource usage by one.
[[Limit#API|limit_interval_reset]]
Reset the interval counter to zero prior to the start of the next interval.
Misc. Commands
bg_system
Execute a system command in the background.
Usage: bg_system
echo
Echo input back to the console echo This text will appear This text will appear
'''Note''' this tests whether FreeSWITCH can see the file, but the file may still be unreadable (permissions).
find_user_xml
Checks to see if a user exists; Matches user tags found in the directory, similar to [[user_exists]], but returns an XML representation of the user as defined in the directory (like the one shown in [[Mod_commands#user_exists|user_exists]]).
Usage: find_user_xml
Where key references a key specified in a directory's user tag, user represents the value of the key, and the domain is the domain the user is assigned to.

+OK
sched_api
Schedule an API call in the future. Usage: sched_api [+@]
time is the UNIX timestamp at which the command should be executed. If it is prefixed by +, specifies the number of seconds to wait before executing the command. If prefixed by @, it will execute the command periodically everyseconds; for the first time it will be executed after seconds. group_name will be the value of "Task-Group" in generated events. "none" is the proper value for no group. command_string is the command executed
Scheduled task or group of tasks can be revoked with sched_del or unsched_api.
You could put "&" symbol at the end of the line to make command to be executed in its own thread.
Play a file to a specific call in the future. Usage: sched_broadcast [+] [aleg|bleg|both]
Schedule execution of an application on a chosen leg(s) with optional hangup: Usage: sched_broadcast [+] app[![hangup_cause]]::args [aleg|bleg|both]
time is the UNIX timestamp at which the command should be executed (or if it is prefixed by +, the number of seconds to wait before executing the command)
Removes a prior scheduled group or task ID Usage: sched_del
The one argument can either be a group of prior scheduled tasks or the returned task-id from sched_api.
Example: sched_del my_group sched_del 2
sched_hangup
Schedule a running call to hangup.
Usage: sched_hangup [+] []
Note: sched_hangup +0 is the same as uuid_kill
sched_transfer
Schedule a transfer for a running call.
Usage: sched_transfer [+] [] []
stun
Executes a STUN lookup. Usage: stun [:port]
Example: stun stun.freeswitch.org
system
Execute a system command.
Usage: system
The command is passed to the system shell, where it may be expanded or interpreted in ways you don't expect. This can lead to security bugs if you're not careful. For example, the following command is dangerous:
If a malicious remote caller somehow sets their caller ID name to "; rm -rf /", you would unintentionally be executing this shell command:
log_caller_name; rm -rf /
time_test
Time test.
Usage: time_test [count]
Runs a test to see how bad timer jitter is. It runs the test count times (default 10) and tries to sleep for mss microseconds. It returns the actual timer duration along with an average.
Sample:
time_test 100 5
test 1 sleep 100 99
test 2 sleep 100 97
test 3 sleep 100 96
test 4 sleep 100 97
test 5 sleep 100 102
avg 98
timer_test
Timer test.
Usage: timer_test <10|20|40|60|120> [<1..200>] []
Runs a test to see how bad timer jitter is. Unlike time_test, this uses the actual freeswitch timer infrastructure to do the timer test and exercises the timers used for call processing.
First argument is the timer interval. Second is the count. Third is the timer name ("show timers" will give you a list)
Retrieves user information (parameters or variables) as defined in the directory.
Usage: user_data @ [attr|var|param]
Where user is the user's id, domain is the user's domain, var|param specifies whether the info we're requesting is a variable/parameter, and the name is the name (key) of the variable.
will return the user's actual alphanumeric ID (i.e. "john") when number-alias="1000" was set as an attribute for that user.
user_exists
Checks to see if a user exists; Matches user tags found in the directory and returns either true/false:
Usage: user_exists
Where key references a key specified in a directory's user tag, user represents the value of the key, and the domain is the domain the user is assigned to.
Example:
user_exists id 1000 192.168.1.101
will return true where there exists in the directory a user with a key called id whose value equals 1000: In the above example, we also could have tested for randomvar:
