Call collision
In the field of telecommunications, a call collision, commonly referred to as a glare, can occur in two situations: Terminal and Data Circuit-Terminating Equipment (DCE) Contention: This type of call collision arises when both a terminal and a data circuit-terminating equipment (DCE) simultaneously designate the same communication channel to initiate a call request and handle an incoming call. In such cases, the DCE prioritizes the call request and proceeds with it, resulting in the cancellation of the incoming call.
