Hi David,
I have added below rules to public.xml file
<extension name="Voicepulse">
<condition field="destination_number" expression="xxxxyyyxx"> // xxxyyyxx -- > my PRI number
<action application="transfer" data="1000 XML default"/>
</condition>
</extension>
After adding this rules, when I am trying to call from mobile to freeSwitch, its says that, number is busy.
