...Now what?
Most hardware codecs, such as the Telos Z/IP ONE, Telos ProSTREAM, and Telos iPort, offer a choice of audio
coding algorithms. With unhelpful names like "G.722", "AAC-LD", and "Layer 2", how does one choose the best
coding algorithm for a given connection or use? A full discussion of audio coding is in Appendix B, Audio Coding
Reference, but the following tables summarize their features at a glance.
