You cant overwrite destination_number with a set command, its not a channel variable, its an element on the caller profile struct.
If you need to reset destination_number you must use the transfer application

Hi,
try this:
<extension name="8 prefix" continue="true">
<condition field="destination_number" expression="^8(0\d{9,15})">
<action application="set" data="dst_number=$1" inline="true"/>
<condition field="${db(exists/${sip_from_user}/cli8}" expression="true">
<action application="set" data="destination_number=${dst_number}" inline="true"/>
<action application="log" data="INFO ${dst_number} ${destination_number}"/>
</condition>
</condition>
</extension>
"destination_number" is a FreeSWITCH variable; it shouldn't be changed.
