Temporary user associations based on call state

An apparatus comprising:

• a network interface unit of a first device configured to send and receive communications over a network;
• and
• a processor coupled to the network interface unit of the first device, wherein the processor is configured to:
• identify when a communication session is established with at least one second device;
• maintain an internal call state model of the first device based on the communication session and device capability information of the first device;
• receive device capability information and contact information for the at least one second device from a user association service;
• compare the device capability information of the at least one second device with the device capability information of the first device to determine at least one compatible capability between the first device and the at least one second device;
• if the at least one compatible capability is determined, create a temporary association between the first device and the at least one second device with the contact information of the at least one second device;
• and
• present an application integration service with the temporary association to establish a secondary communication link between the first device and the at least one second device through an external service.

One or more non-transitory computer readable storage media encoded with software comprising computer executable instructions, and when the software is executed, operable to:

• identify, at a first device, when a communication session is established with at least one second device;
• maintain an internal call state model of the first device based on the communication session and device capability information of the first device;
• receive device capability information and contact information for the at least one second device from a user association service;
• compare the device capability information of the at least one second device with the device capability information of the first device to determine at least one compatible capability between the first device and the at least one second device;
• if the at least one compatible capability is determined, create a temporary association between the first device and the at least one second device with the contact information of the at least one second device;
• and
• present an application integration service with the temporary association to establish a secondary communication link between the first device and the at least one second device through an external service.
