*67 is staying activated on my linksys spa942 ip phone, until the phone is restarted. All I am doing is dialing *67 + number, which works great but then the next call I make has the caller id blocked as well. I tried to do *67 again to see if it turns off but it doesn't. Any ideas? I know it is the phone and not the carrier, because I can see that it continues to send anonymous in a sip trace on my Asterisk box.
