Abstract
A device may receive a first call associated with a virtual phone number associated with a first user device and a second user device. The device may determine, and may store information indicating, that the first call was made using the first user device. The device may receive a second call directed to the virtual phone number and may determine whether the second call comprises a call back associated with the first call. The device may selectively send the second call to the first user device or to the first and second user devices based on determining whether the second call comprises the call back. The second call may be sent to the first and second user devices when the second call does not comprise the call back and may be sent to the first user device when the second call comprises the call back.
