Automated property access control involving sequential call prompt interactions using multiple computing devices

A computer-implemented method comprising:

• receiving, by one or more computing devices, information about a first request for an indicated first user to obtain access to an indicated physical property at one of multiple availability times together with a second user that is not yet identified and is authorized to access the indicated physical property under one or more specified conditions, wherein the indicated physical property is under control of at least one third user who is unaffiliated with the first user and the second user;
• and
• confirming, by the one or more computing devices and in response to the first request, the access to the indicated physical property by the first user together with the second user via multiple electronic communications of multiple types, including:
• determining, by the one or more computing devices, a plurality of alternative candidate users to be the second user, and selecting a current candidate user from the plurality of alternative candidate users to receive a second request to act as the second user for the access to the indicated physical property;
• initiating, by the one or more computing devices, a telephone Voice Over Internet Protocol (VOIP) call to a client computing device of the current candidate user on behalf of the first request for the first user;
• sending, by the one or more computing devices, the multiple electronic communications of the multiple types to the client computing device to cause a response from the client computing device, including sending a push notification message to the client computing device to initiate access to a copy of an application program on the client computing device, and further including sending one or more audio transmissions over the telephone VoIP call for presentation on a speaker associated with the client computing device, and further including sending data communications with included information to the copy of the application program to cause display of the included information in a graphical user interface of the copy of the application program that indicates the multiple availability times and that includes user-selectable controls for the current candidate user to either decline participation in the access to the indicated physical property, or to agree to the participation as the second user in the access to the indicated physical property at a user-selected one of the multiple availability times;
• and
• updating, by the one or more computing devices and in response to the current candidate user agreeing to the participation in the access to the indicated physical property at the selected one availability time and in accordance with the specified one or more conditions, calendar data for the current candidate user to include the selected one availability time for the access to the indicated physical property by the first user and by the current candidate user acting as the second user.

A non-transitory computer-readable medium having stored contents that cause one or more computing devices to perform automated operations including at least:

• receiving, by one of the one or more computing devices, and based at least in part on a first request from an indicated first user to obtain access to an indicated physical property at one of multiple availability times together with a second user that is not yet identified and is authorized to access the indicated physical property under specified conditions, multiple electronic communications of multiple types including an incoming telephone Voice Over Internet Protocol (VOIP) call corresponding to a second request to a user of the one computing device to act as the second user for the access to the indicated physical property and further including a push notification message sent to the one computing device to initiate access to a copy of an application program on the one computing device, wherein the user of the one computing device is selected from a plurality of alternative candidate users to be the second user, and wherein the indicated physical property is under control of at least one third user who is unaffiliated with the first user and the second user;
• activating, by the one computing device and in response to receiving the push notification message, the copy of the application program executing on the one computing device to show first user-selectable controls for answering or rejecting the telephone VOIP call, and receiving a selection by the user of the one computing device of one of the first user-selectable controls for answering the telephone VoIP call;
• receiving, by the one computing device, additional electronic communications of the multiple types for the second request, including one or more audio transmissions over the telephone VoIP call related to the access to the indicated physical property and for presentation on a speaker associated with the one computing device, and further including one or more data communications separate from the telephone VOIP call with supplied information about at least the multiple availability times and the indicated physical property to cause presentation of the supplied information in a displayed graphical user interface (GUI) of the copy of the application program;
• presenting, by the one computing device and to the user of the one computing device, the one or more audio transmissions over the telephone VoIP call on the speaker, and updates in the displayed GUI of the copy of the application program that include the supplied information from the one or more data communications and that further include second user-selectable controls for the user of the one computing device to either decline participating in the access to the indicated physical property, or to agree to participation as the second user in the access to the indicated physical property at one of the multiple availability times that is selected by the user of the one computing device via the second user-selectable controls;
• receiving, by the one computing device and in response to the user of the one computing device agreeing to participate in the access to the indicated physical property at the selected one availability time, one or more further electronic communications to provide confirmation of the access to the indicated physical property by the first user and by the user of the one computing device acting as the second user at the selected one availability time in accordance with the specified conditions, and initiating updating of calendar data for the user of the one computing device to include the selected one availability time;
• and
• presenting, by the one computing device, information about the received confirmation in the displayed GUL of the copy of the application program.

A system comprising:

• one or more hardware processors of one or more computing devices;
• and
• one or more memories with stored instructions that, when executed by at least one of the one or more hardware processors, cause the one or more computing devices to perform automated operations including at least:
• receiving information about a first request for a first user to obtain access to an indicated physical property at one or more availability times together with a second user that is not yet identified and is authorized to access the indicated physical property;
• and
• confirming the access to the indicated physical property by the first user together with the second user, including:
• determining one or more candidate users to be the second user, and selecting a current candidate user from the one or more candidate users to receive a second request to act as the second user for the access to the indicated physical property;
• sending multiple electronic communications of multiple types to a client computing device of the current candidate user to cause a response, including sending a push notification message to the client computing device to initiate access to a copy of an application program on the client computing device, and further including sending one or more audio transmissions over a telephone call for presentation on the client computing device, and further including sending one or more data communications with included information to the copy of the application program to cause display of the included information in a graphical user interface of the copy of the application program that indicates the one or more availability times and that includes user-selectable controls for the current candidate user to either decline participating in the access to the indicated physical property, or to agree to participation as the second user in the access to the indicated physical property at one of the one or more availability times;
• and
• initiating, in response to the current candidate user agreeing to participate in the access to the indicated physical property at the one availability time, updating of calendar data for the current candidate user to include the one availability time for the access to the indicated physical property by the first user and by the current candidate user acting as the second user.
