Anonymous Call Rejection
Anonymous call rejection – this is a function that blocks the incoming calls of subscribers with indefinite telephone number.
People calling from an indefinite number can very often hear a message that this line does not receive calls with indefinite subscriber numbers.
A modern voice communication SIP protocol is widely used to make calls in the Internet. However, the final subscriber is mostly interested not in the very SIP standard but in the SIP telephony conception based on it.
One one hand, all traditional conveniences for making telephone calls, compatibility with the international subscription base and the procedure of dialing numbers are kept.
