发明名称 Multiple simultaneously active telephone calls
摘要 A method and system for providing a user who places a telephone call on hold with a partial hold option. When a user places a first call on partial hold and picks up a second call, the user can still hear conversation and activity that occurs on the first call. For example a user participating in a conference call may receive a second call. The user can place the conference call on partial hold and pick up a second call (i.e. engage in a conversation on a second telephone call). However, the incoming channel to the conference call will remain active and the user will be able to hear, in the background, what is taking place in the conference call. Should the user hear something interesting in the conference call, or if the user hears someone ask a question directed to the particular use, the user can switch back to the conference call.
