FreeSWITCH 1.8

Match an IP address and Caller ID

In this example, we need to match a called number beginning with the prefix 1 and match the incoming IP address at the same time.

<extension name="Test2"> 
  <condition field="network_addr" 
    expression="^192\.168\.1\.1$"/> 
  <condition field="destination_number" expression="^1(\d+)$"> 
    <action application="bridge"  
      data="sofia/profilename/$0@192.168.2.2"/> 
  </condition> 
</extension> 

Here, although we match with the rule ^1(\d+)$, we don't use the variable $1, which would contain only the rest of the dialed number with the leading 1 stripped off. Instead, we use the variable $0 that contains the original destination number.
