A computer device may include a memory configured to store instructions and a processor configured to execute the instructions to detect a Session Initiation Protocol (SIP) call and identify an available technology type to carry the SIP call from an originating device. The processor may be further configured to execute the instructions to generate an originating available technology type header that includes information identifying the identified available technology type to carry the SIP call from the originating device and forward the SIP call toward a destination with the generated originating available technology type header.
