[SR-Users] Caller ID using From header

[Alex Balashov]

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.
