Here's what we do for our PRI
In the sip.conf section for each of your customers, you add a line:

callerid="My Corp" < 3106548899 >

(change the name and number of course).

Asterisk will pass this through to your provider on outbound calls  
from this user.
(Unless you explicitly do a Set(CallerIDnum= ) somewhere else) in  
extensions.conf

My provider only wants the last 5 digits sent, so I do a:

exten => _0.,4,SetCIDNum(${CALLERIDNUM:5})

Just before the actual dial.
