13. The network processing device according to claim 9 wherein the processor specifics a first sequentially increasing packet number sequencing for the combination of IP media and IP text packets in the real-time IP transport session and specifies a second different sequentially increasing packet number sequencing just for the IP text packets.
9. A network processing device, comprising: a processor configured to: convert media signaling into Internet Protocol (IP) media packets; receive text signaling comprising different analog audio tones representing different alpha-numeric characters; identify the alpha-numeric characters represented by the analog audio tones and generate digital values that represent the same identified alpha-numeric characters; formatting the digital values into IP text packets absent analog signaling characteristics describing the audio tones; and sending the IP media packets and the IP text packets in interleaved manner over an IP network using the same real-time IP transport session.
