The system has a Voicemail Session Monitor and an Interrupt Handler. In the method of the present invention, the voicemail connection is monitored by the recipient's phone and interrupted when the line is picked up, connecting the two parties if the calling party accepts the invitation. The receiving party is offered an invitation to accept the interrupt or to allow the calling user to stay in the voicemail system. ## Claims ### Claim 1 A voicemail system for interrupting a voicemail session between a first user and a voicemail box of a second user, the system comprising: a network input/output device associated with a cellular network and configured to receive and send call-related information between the first user and the second user; a voicemail box configured to receive and store a voicemail message associated with a cellular phone call from the first user to the second user, wherein the cellular phone call is to be initiated from a first cellular device associated with the first user to a second cellular device associated with the second user using the cellular network; and an interrupt handler configured to handle an interrupt request from the second cellular device to interrupt the voicemail session while the voicemail message is being received by the voicemail box of the second user, wherein the interrupt request is to be associated with a monitoring of the voicemail session between the first user and the voicemail box; wherein the interrupt handler is configured to interrupt the voicemail session based on the interrupt request being received while the voicemail is being received by the voicemail box of the second user and is configured to issue an interrupt invitation to the first user, and wherein the first user is enabled to accept or not accept the interrupt invitation, and wherein based on the first user accepting the interrupt invitation, the second user is notified that the second user is being redirected to the first user and/or the first user is notified that the first user is being directed to the second user. ### Claim 2 (depends on 1) The voicemail system of claim 1, wherein, based on the first user accepting the interrupt invitation, the voicemail message is deleted. ### Claim 3 (depends on 1) The voicemail system of claim 1 wherein the interrupt handler further comprises a session monitor configured to monitor the voicemail session between the first user and the voicemail box. ### Claim 4 A method for interrupting a voicemail message being left on a second user's voicemail box, when a first user is attempting to contact the second user, the method comprising: receiving a phone call attempt from a first cellular device of the first user to a second cellular device of the second user via a cellular network; determining that the second user has not accepted the phone call based on a predetermined factor; redirecting the first user to a voicemail box of the second user; establishing a voicemail session between the first user and the voicemail box of the second user; receiving, from the second cellular device, an interrupt request associated with a monitoring of the voicemail session, while the voicemail session is active; enabling the first user to have an option to accept or not accept the interrupt request; and based on whether the first user has accepted the interrupt request, connecting the first cellular phone and the second cellular phone to enable a conversation between the first user and the second user and automatically deleting the voicemail message from the first user to the second user. ### Claim 5 (depends on 4) The method of claim 4 further comprising: providing a notification to the first user that the second user has issued an interrupt request. ### Claim 6 (depends on 4) The method of claim 4 wherein the redirecting the first user to the voicemail box of the second user comprises offering an invitation to the first user to have a voicemail session with the voicemail box. ### Claim 7 (depends on 4) The method of claim 4, wherein based on the first user accepting the interrupt request, the first cellular phone and the second cellular phone are connected in a conversation. ### Claim 8 (depends on 4) The method of claim 4, wherein based on the first user not accepting the interrupt request, the first user is enabled to continue leaving the voicemail message in the voicemail box. ### Claim 9 (depends on 4) The method of claim 4 further comprising: based on the first user accepting the interrupt invitation, notifying the second user that the second user is being redirected to the first user. ### Claim 10 (depends on 4) The method of claim 4 further comprising: based on the first user accepting the interrupt invitation, notifying the first user that the first user is being redirected to the second user. ### Claim 11 A computer software program comprising program code stored on a non-transitory computer-readable medium, which when executed, enables a computer system to implement a method for interrupting a voicemail message being left on a second user's voicemail box, the method comprising: receiving a phone call attempt from a first cellular device of the first user to a second cellular device of the second user via a cellular network; determining that the second user has not accepted the phone call based on a predetermined factor; redirecting the first user to the voicemail box of the second user; establishing a voicemail session between the first user and the voicemail box of the second user; receiving, from the second cellular device, an interrupt request associated with a monitoring of the voicemail session, while the voicemail session is active; and wherein the first user is enabled to accept or not accept the interrupt request, and wherein if the first user accepts the interrupt request, the first user and the second user are connected in a conversation via the cellular network and the voicemail message from the first user to the second user is automatically deleted. ### Claim 12 (depends on 11) The computer program product of claim 11 further comprises providing a notification to the first user that the second user has issued an interrupt request. ### Claim 13 (depends on 11) The computer program product of claim 11 wherein the redirecting the first user to the voicemail box of the second user comprises offering an invitation to the first user to have a voicemail session with the voicemail box. ### Claim 14 (depends on 11) The computer program product of claim 11 wherein if the first user does not accept the interrupt request, the first user is enabled to continue leaving a voicemail message in the voicemail box. ### Claim 15 (depends on 11) The computer program product of claim 11 wherein if the first user accepts the interrupt invitation, the second user is notified that the second user is being redirected to the first user. ### Claim 16 (depends on 11) The computer program product of claim 11 wherein if the first user accepts the interrupt invitation, the first user is notified that the first user is being redirected to the second user.
