[Freeswitch-users] Strip digits from incoming caller id

[Michael Collins]

Georg,

If you just want the phone number w/o the international prefix then it's
better to capture that correctly the first time:
<condition field="destination_number" expression="^(49)?(123456789)$">
The value you want is now in $2, and if it's international then you'll have
"49" in $1. However, you cannot use $1 or  $2 in another condition. You'll
need to store them before you do anything else:

<extension name="Dispo Intern" continue="true">
  <condition field="destination_number" expression="^(49)?(123456789)$">
    <action application="set" data="international=$1" inline="true"/>
    <action application="set" data="dialed_number=$2" inline="true"/>
  </condition>

  <condition field="${international}" data="^49$">
    <action application="set"
data="effective_caller_id_number=0${dialed_number}"/>
    <action application="set" data="effective_caller_id_name=_undef_"/>
    <anti-action application="set"
data="effective_caller_id_number=${dialed_number}"/>
  </condition>

</extension>

Try that. Standard disclaimer applies: I did that off the top of my head,
so if it doesn't work the first time please test and tinker a bit before
you report back. :)
