asterisk users - May 2013 - SetCallerPres questions

Does SetCallerPres(Prohib) remove the ANI data from a SIP call or does 
it simply set a flag telling other devices not to display the data?

In other words, could another system override that and see the caller ID 
anyway?  The answer may affect how I handle 911 calls, so I'm very curious.

Hi,

In 1.8 setting this flag it does not remove any caller id related data,
it just sets an information on how to handle the data.
If the direct dial target is a phone, it MAY show the callerid anyway,
but dialling out on a PSTN/VoIP trunk also sends the callerid.

But: If you place an emergency call the emergency service should always
be able to see your callerid - even if you set SetCallerPres(Prohib).
