Daniel,
It's a common problem. The simplest solution - especially if you don't want to modify the From header - is to use one of the headers that superecedes From: P-Asserted-Identity, or Remote-Party-ID (deprecated draft, but very widely used).
Almost all commercial gateways and softswitches prefer them in this order of precedence: PAI, RPID, From.

Wondering what others are doing / looking for any tips for the best handling of caller ID in this scenario.
Call flow –
UA >> Proxy >> Asterisk >> Proxy >> Carrier
Carrier only reads caller ID by ‘From header’
Asterisk is only used for media functions / b2bua and not user aware.
UA username is not a DID but rather some other string, such as ‘dan@domain.com’.
Goal is to use DID for caller ID, but I like to avoid modifying the ‘From header’.
Any thoughts?
