it is necessary to make as

From: "USERNAME_STRING" <sip:USERNAME_STRING@172.30.0.1>;tag=9DcB7gSNZZ41j

You have to use
<action application="set" data="effective_caller_id_name=USERNAME_STRING"/>
<action application="set" 
data="effective_caller_id_number=USERNAME_STRING"/>

in dialplan before bridging, or in users directory profile.
