[Freeswitch-users] Logical AND + NOT

[Scott]

<!-- eavesdrop -->
<extension name="record_3..16_digits" continue="true">
<condition field="${is_already_recording}" expression="^$"/>
<condition field="destination_number" expression="(?!^399|400$)^\d{3,16}?$"
>  <!-- regex#2 -->
  <action ... />
</condition>

"regex#2", as written, returns TRUE providing that dest_num matches a
'\d{3,16} pattern but is NOT 399 or 400.  Therefore,

399 = false
400 = false
4001 = true
4005551212 = true
416 = true
4165551212 = true
1234 = true
ANONYMOUS = false

There is very, very little that CANNOT be done with native regex.

If you need me to "explain" the regex construction, let me know.

Cheers,
/Scott
