If your internal numbers always match your outside numbers just prefix it

SetCallerID("Company Name" <00312010000${CALLERIDNUM}>)

If outside numbers do not always match internal numbers you can use the 
astdb to help

First populate the database
CLI> database put outcid 208 00312010000208
CLI> database put outcid 209 00312010000209
etc.

Second create a macro (not tested)

[macro-setclid]
exten => s,1,DBGet(clid=outcid/${CALLERIDNUM})
exten => s,2,SetCallerID("Company Name" <${clid}>)
exten => s,102,SetCallerID("Company Name" < -- main company number here 
-- >)

Then before you dial it's as easy as

Macro(setclid)

This is similar to what I am currently using  to tackel this exact problem.
