Abstract: Message-based interactive voice response (IVR) menu reconnection is used to reconnect a calling device to a destination at a specific node of a call path after the calling device disconnects from a call with the destination. Menu options of an IVR service presented during a call between the calling device and the destination are determined responsive to the calling device disconnecting from the call. A message including one or more selectable elements each associated with one of the menu options is then transmitted to the calling device.

Thus, where the calling device had partially or fully traversed an IVR service during the call, the message-based IVR menu reconnection disclosed herein enables the calling device to reconnect to the destination without having to repeat that IVR service traversal.
