When you set sendrpid=yes in sip.conf, a very nice feature is activated. When dialing an extension, the callerid of the dialed extension is returned back on the display of the calling phone. So if you call extension 100, you can see you are calling Ann (for example).
I want to selectively disable the transmission of this information back to the caller. How can I do it?
I tried setting
but it doesn’t seem to sort any effect.
Where am I wrong?
