1. A method comprising:
- communicating, by a wireless device, in a communications session over a cellular network with a remote endpoint device;
detecting, based on the wireless device measuring a signal strength of a wireless signal transmitted by a cellular access network node of the cellular network, a condition indicating potential loss of wireless connectivity by the wireless device with the cellular network or actual loss of wireless connectivity by the wireless device with the cellular network; and
in response to the detecting, sending, by the wireless device, a Session Initiation Protocol (SIP) request to a service that supports asynchronous communications to establish a session with the service that supports asynchronous communications, the SIP request causing a transfer of communication with the remote endpoint device to a communication path including a wireless connection with the cellular network, and the service that supports asynchronous communications, the wireless device to communicate wireless signals with the cellular network over the wireless connection, and the transferred communication with the remote endpoint device comprising a communication of data between the wireless device and the remote endpoint device through the communication path including the wireless connection and the service that supports asynchronous communications.

Abstract
In some examples, a wireless device communicates in a communications session over a cellular network with a remote endpoint device. The wireless device detects a condition indicating potential loss of wireless connectivity or actual loss of wireless connectivity with the cellular network. In response to the detecting, communication with the remote endpoint device is transferred to a communication path including a service that supports asynchronous communications.
