Very sorry, I forgot, the last time I updated my CVS checkout was Sept 19th

That is not the correct way to suppress Caller ID. CallerPres should be used to mark the Caller ID as 'restricted presentation', without removing it. If you remove the Caller ID completely, then it's gone.

From what I understand, presentation restriction is only available for ZAP channels, and this is a SIP only system and therefore it will not work this way. Please let me know if I'm wrong.

Additionally, the source really should be the username portion of the From URI, don't you think on a SIP call?

Don't go by 'what you understand'... try it out. chan_sip correctly suppresses the CLID/CNAM information when it has been marked as restricted, unless it is being sent to a peer that understands RPID (and that has been enabled).
