Abstract
The invention provides a method and a system for establishing a push-to-talk hands-free call. The method comprises the following steps: a calling device is added with a 'push-to-talk' button, and the calling device triggers a call through the 'push-to-talk' button and sends a call establishing request to a switching device; the switching device detects whether the call establishing request contains 'push-to-talk' function representation information after receiving the call establishing request; if the call establishing request contains the 'push-to-talk' function representation information, the switching device sends an off-hook instruction containing the 'push-to-talk' function representation information to a called device; and when receiving the off-hook instruction containing the 'push-to-talk' function representation information, the called device is automatically switched to an off-hook state according to the off-hook instruction to establish a call with the calling device. According to the invention, the 'push-to-talk' function is added on the basis of the traditional telephone, so that a called telephone can be automatically switched to an off-hook state to establish a call with a calling telephone quickly. The method and the system are especially applicable to special environments or occasions in which the called party cannot pick up the phone.
