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?
