Abstract: A call processing method, a call processing system and call processing equipment of a same number service are disclosed. The method includes: receiving a call which is initiated by a calling client and carries an initial called number, and sending a message of the called number with a same number service characteristic to first switching equipment in an IP network when the initial called number is a number of the same number service; and receiving a call request initiated by the first switching equipment, starting same number service processing of the initial called number according to the message carried in the call request, and calling a same number terminal corresponding to the initial called number. The embodiment of the invention helps realize the same number service between a SIP intelligent terminal in the IP network and ordinary terminals in other communication networks.
