Patent number: 7796741Abstract: The invention provides a call connection control method which can use a conventional telephone as-is and performing linking with a low possibility of mistaking telephones, and a call connection control unit for implementing the method. Upon receiving an outgoing call request from an outgoing-call side personal computer (PC), a call connection control unit retrieves an outgoing-call side IP-telephone linked to the PC, and transmits an incoming call request to the IP-telephone. Upon receiving the incoming call request, the IP-telephone rings. When the caller places the IP-telephone that rings in a starting (off-hook) state, the call connection control unit sends a ring back tone to the IP-telephone and transmits an incoming call request to an incoming-call side IP-telephone. Upon receiving the incoming call request, the IP-telephone rings. When the recipient places the IP-telephone that rings in a starting state, the call connection control unit enables a call between the two IP-telephones.Type: GrantFiled: September 7, 2006Date of Patent: September 14, 2010Assignee: Hitachi Communication Technologies, Ltd.Inventors: Fumio Urayama, Tatsuya Yoshida, Shinji Saitou

Publication number: 20070121827Abstract: The invention provide a call connection control method of using a conventional telephone as-is and performing cooperation with low possibility of mistaking the telephone and a call connection control unit for implementing the method. On receiving an outgoing request from an outgoing-side Personal Computer, a call connection control unit searches for an outgoing-side IP-Telephone which is cooperated, and transmits an incoming request to the IP-Telephone. On receiving the incoming request, the IP-Telephone sounds a ringing tone. If a caller puts the IP-Telephone having sounded the ringing tone in a Starting State, the call connection control unit sends out a Ring Back Tone to the IP-Telephone and transmits an incoming request to an incoming-side IP-Telephone. On receiving the incoming request, the IP-Telephone sounds a ringing tone.Type: ApplicationFiled: September 7, 2006Publication date: May 31, 2007Inventors: Fumio Urayama, Tatsuya Yoshida, Shinji Saitou
