[asterisk-users] Setting RPID privacy?

[Rushowr]

Hello all,

Just had a question that I've not been able to find a suitable answer for.
When we receive calls on SIP, we can get SIP_HEADER(Remote-Party-ID) and
check the privacy flag for what privacy is requested. Now, since SIP_HEADER
is not writable, how can I set the privacy flag in the RPID header? Should I
just use CallingPres? Just set the CID to RESTRICTED <>? 

Any hints, suggestions?
