[Serusers] Grandstream BT100 Shows Caller ID Even With RPID privacy=full

[Java Rockx]

Jiri,

I started down that road of thinking until I realized that having the SIP proxy alter the FROM
header was a bad thing.

I wish there were some way, from the ser proxy, to guarantee blocking caller ID for both SIP->PSTN
and SIP->SIP calls.

Our situation is that we need to ship IADs/ATAs to customers preconfigured and locked down to keep
customers from messing up their settings and to keep them from knowing their SER
username/password.  So we can't allow users to permanently enable caller id blocking on their ATA.

I guess *67 is my only choice for now, but this has to be dialed every time a subscriber calls
someone :-(

Regards,
Paul
