[Asterisk-Users] Anonymity and Privacy headers

[Manuel Wenger]

When a user calling over the PSTN network calls one of our SIP users with a restricted number (CLIR), our PSTN gateway is sending us incoming calls with the following additional headers:


Proxy-Require: privacy
Anonymity: uri
Remote-Party-ID: <sip:41781234567 at 192.168.0.100:4000>;privacy=uri


as opposed to


Remote-Party-ID: <sip:41781234567 at 192.168.0.100:4000>;privacy=off


when CLIP is enabled (thus CLIR is disabled).

Any ideas on how I can tell asterisk to process one (or more) of these headers, and strip the CLI before sending the call out to our SIP users, in case it is restricted? I have searched the Wiki and read the chan_sip.c source code, but didn't find anything useful...

Thanks
-Manuel
