Abstract
A computer-implemented method for inserting an out-of-band signaling packet into a real-time protocol (RTP) stream is provided. The method includes receiving the out-of-band signaling packet intended for transmission to a user device and forming a synthesized packet based on payload information from the out-of-band signaling packet and header information stored in a data structure describing the RTP stream. The method also includes inserting the synthesized packet into the RTP stream. The method further includes receiving an RTP packet intended for transmission to the user device via the RTP stream, analyzing an insertion sequence number and an insertion flag maintained in the data structure, and discarding or forwarding the RTP packet via the RTP stream based on the analyzing.
