Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] In order to realize the problem of combining the hotline method and the ordinary dialing method in the voice gateway, the method of warm line registration in the voice gateway can be adopted, so that if the user does not enter any number within a certain period of time, the user will be disconnected after the timeout. Make a call using a registered number. by figure 2 For example, if the destination address of the warm line service of communication device A is the address of communication device C, when the calling communication device A initiates a call, if the calling communication device A has registered for the warm line service at this time, it will be the calling device A The call applies for a warm line service timer. If the calling device A dials a new phone number within the set time, assuming it is the number of the communication device B, ...

The invention discloses a method for a hotline service based on internet voice gateway. The method judges the received application through calling voice gateway, if the application is applying the service or canceling it, registers the appliance and target address needed hotline service or deletes the appliance and target address in calling voice gateway.
