TwoFast,
I want to confirm that a reboot is NOT necessary after you enable AnonymousCallBlock feature using *code (by default, to block is *77; to unblock is *87).
I have just tried that for about 10 times, using both version 1.2.0.2101 and 1.1.0.1892, both seems to be working as expected. I tried calling the unit's SP2 and OBiTALK services, the phone rings if I show my caller-id number, but will get busy tone if I hide my caller-id number.
Also tried *87 to unblock it again; and it too does not need to reboot the unit to take effect.
After you dial *77 (or *87) from the phone, the unit should return dial tone immediately; this is the indication that the * code you entered is valid.
If you can access the device's web page, you can also check under SP1/SP2/LINE/OBiTALK Service - CallingFeatures, that the AnonymousCallBlockEnable parameter is checked after you dial *77, and unchecked after you dial *87, and no reboot is needed.
Please try it out a few times again and see if this works consistently.
