PURPOSE:To insert a talking request message of the 3rd subscriber without such as hooking by the 1st subscriber by reconnecting a channel to an incoming trunk when the 1st subscriber receives an incoming from the 3rd subscriber during talking with the 2nd subscriber. CONSTITUTION:When an incoming arrives from the 3rd subscriber C to the 1st or the 2nd subscriber while the 1st subscriber A and the 2nd subscriber B are talking, the 1st and 2nd subscribers are connected to the incoming trunk 5 from a talking trunk 4 in response to a request of the 3rd subscriber C and the 3rd subscriber C is connected to the incoming trunk 5. While the channel state of the 1st and 2nd subscribers is kept in the incoming trunk, a talking request message is inserted only to one subscriber from the 3rd subscriber C and it is noticed, and the subscriber receiving the notice is connected to the 3rd subscriber in response to the response request of the subscriber receiving the notice and the other subscriber is held. |
