Abstract:
A method for facilitating a call session includes receiving a request to establish a call session between a wireless phone and a remote phone, and establishing a call session between the wireless phone and the remote phone. The call session includes a first connection with the wireless phone and a second connection with the remote phone. The method further includes monitoring the first connection to determine if there is a connection loss of the first connection, and determining that there is a connection loss of the first connection. In response to determining that there is a connection loss of the first connection, the method further includes holding the second connection with the remote phone, attempting to reestablish the first connection with the wireless phone, and resuming the call session in response to the first connection being reestablished.
