Supporting hands-free services via a hands-free device for IP video calls

A non-transitory machine-readable storage medium that provides instructions that, when executed by a processor, will cause the processor to perform operations for providing hands-free services for Internet Protocol (IP) video calls through a hands-free device, the operations comprising:

• receiving an IP video call invitation request specific to the client computing device that requests the client computing device to participate in a P2P (peer-to-peer) IP video call;
• generating a generic incoming call object based on the IP video call invitation request in a format that is common for both incoming audio only cellular calls and IP video call invitation requests, the incoming call object including a set of parameters regarding the incoming call, wherein the set of parameters regarding the call includes a status of the call, a call participant identifier, a start time, and a call identifier;
• alerting the hands-free device of the incoming call based on the incoming call object;
• responsive to receiving an indication from the hands-free device that a user has indicated to answer the incoming call, transmitting a device specific IP video call accept message;
• establishing a P2P connection for the P2P IP video call;
• and
• routing an audio portion of the P2P IP video call through the hands-free device such that the hands free device acts as an auditory relay during the P2P IP video call.

A client computing device, comprising:

• a processor system including a system on an integrated circuit;
• an internet protocol (IP) video call manager coupled to the processor system, to manage establishment of IP video calls and to generate and transmit a first call object, the first call object including a set of parameters regarding the IP video call;
• a cellular call manager coupled to the processor system, to manage establishment of audio only cellular calls, and to generate and transmit a second call object, the second call object including a set of parameters regarding the audio only cellular call, wherein the first call object and second call object have a common format, and wherein the set of parameters regarding the IP video call and the set of parameters regarding the audio only cellular call each include a status of the call, a call participant identifier, a start time, and a call identifier;
• a telephony manager coupled with the processing system, the IP video call manager and the cellular call manager to provide hands-free services via an external hands-free device for both IP video calls and audio only cellular calls on behalf of the IP video call manager and the cellular call manager, the hands-free services including:
• answer an incoming call via the external hands-free device, end a call via the external hands-free device, and initiate a call via the external hands-free device;
• and
• a hands-free manager coupled to the telephony manager, to establish an audio connection with the hands-free device, wherein the hands-free manager sends a request to an audio manager to route an audio portion of the IP video call through the hands-free device while a video portion of the video call is displayed on the client device.
