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

Well, it seems to assume model in which content of caller id is intended for use by PSTN gateways that see just the caller id and don't care about content of From then. So all it does is it enables privacy in the caller id. I think it would make sense to use "anonymous" From in that case too.

Hi All.
Does anyone know why my grandstream BT100 firmware 1.0.5.16 shows the caller ID rather than "anonymous" even though I have Remote-Part-ID enabled with privacy=full?
Below is the INVITE message sent to the BT100 from a UTstarcom ATA.
