[Freeswitch-users] Keeping local calls local

[Stanislav Sinyagin]

here's a piece of my dialplan in "default" context. It simply catches such calls and transfers them directly to the public context. The public context matches local DID numbers and transfers them to corresponding extensions in default context:

    <extension name="internal_did">
      <condition field="destination_number" expression="^($${default_did_prefix}\d+)$">
        <action application="transfer" data="$1 XML public"/>
      </condition>
    </extension>


The "default_did_prefix" variable holds my DID number block.
