One-tap conference calling on devices

A method comprising:

• sending, to a server, a request to establish a mobile conference room through a conferencing application on a client device;
• receiving, from the server, a message indicating that the mobile conference room has been established according to the request;
• sending, to the server, data regarding one or more contacts to be added to the mobile conference room, wherein each of the one or more contacts are notified of being added to the mobile conference room;
• selecting, by a user of the client device through a user interface of the client device, a subset of contacts from the contacts added to the mobile conference room for a conference call;
• sending, to the server, an unscheduled request to initiate a conference call between the client device and the subset of contacts in the mobile conference room, wherein each of the subset of contacts are called concurrently by the server;
• and
• in response to receiving the unscheduled request to initiate the conference call, launching the conference call through the conferencing application on the client device, wherein the client device and all contacts that have answered the call are bridged on the conference call by the server.

A system comprising:

• at least one processor;
• and at least one memory storing computer-readable instructions that, when executed by the at least one processor, cause the system to receive, from a client device, a request to establish a mobile conference room, the request originating from a conferencing application on the client device;
• establish the mobile conference room based on the request by assigning a phone number to the mobile conference room;
• send, to the client device, a message indicating that the mobile conference room has been established according to the request;
• receive, from the client device, data regarding one or more contacts to be added to the mobile conference room;
• add the one or more contacts to the mobile conference room based on the received data;
• receive, from the client device, an unscheduled request to initiate a conference call with a subset of contacts in the mobile conference room;
• the subset of contacts selected from the contacts in the mobile conference room through a user interface of the client device;
• concurrently call each of the subset of contacts in the mobile conference room in response to the unscheduled request;
• determine which of the subset of contacts have answered the call;
• and bridge the client device and all contacts that have answered the call on the conference call.
