Define "Caller ID":

- From URI
- P-Asserted-Identity
- Remote-Party-ID

Either way, the proxy can strip/modify/add the latter two. Proxies 
aren't supposed to modify the From header because it violates message 
integrity, but Kamailio has a hacky way of getting around this:

So, long story short, yes, Kamailio can modify "caller ID".
