Abstract
The system receives a SIP call from a UE associated with the user. The SIP call includes a call setup phase and a data transfer phase, where the call setup phase precedes the data transfer phase. The call setup phase includes an exchange of multiple header fields. The system obtains the multiple header fields from the SIP call. The system determines that the call is an open-line call by identifying an optional field within the multiple header fields, where the optional field indicates that the call is the open-line call. The open-line call indicates that the user of the UE cannot engage in a conversation with a receiver of the open-line call. Upon determining that the call is the open-line call, the system notifies an operator receiving the SIP call to not engage in an audible conversation with the user.
