These are most often found in Polycom phones, but they are available elsewhere. The only widely supported HD codec is G.722. Pretty much anything offering wideband voice supports G.722. Except skype which only supports SiLK as the HD codec. I mention this because most people's experience with HD will be in a Skype-to-skype call, although admittedly not in this group. That's a very good point, although Skype does support more codecs than just Silk, and I believe G.722 may be one of them. Nonetheless, it is Silk that people have got used to. It offers about 11kHz bandwidth, so it is wider band than G.722. The critical addition than wideband gives over normal telephony is the 5kHz to 7kHz area, where a lot of the energy that allows us to differentiate the unvoiced phoneme lies. The energy between 7kHz to 15kHz does, however, add a lot to the human voice, and allows for a more relaxed listening experience - its just less tiring to listen to.

What I know (from implementing these codecs) is that the source code Polycom provide licencees, as the basis for developing their own G.722.1 and G.722.1C codecs, has several comments referring to things not being quite the same as Siren7/Siren14. However, they don't hand out the actual Siren7/Siren14 source code, so I don't know how much divergence there is.

Re: [asterisk-users] Are the Siren7 and Siren14 the G.722 HD voice codecs?
On 01/05/2011 01:29 AM, Bruce B wrote: Hi Everyone, You should really spend some time learning how to use a widely available search engine, such as Google or Bing. Many of the questions you ask here could be quickly answered that way. 1- Are the Siren7 and Siren14 the G.722 HD voice codecs? That depends on what you mean by the G.722 HD voice codecs. G.722 (no suffix or annex) is a specific voice codec, and it is unrelated to Siren7 and Siren14. G.722.1 is the same thing as Siren7, and G.722.1 Annex C is the same thing as Siren14. These are fairly well explained on the Wikipedia pages for G.722 and G.722.1. 2- Are these codecs only for Polycom units or are they universal across all other SIP phones that advertise the HD voice codec like Aastra? There is no the HD voice codec. The most widely available HD voice codec is G.722, but there are others available as well in endpoints from various manufacturers. G.722.1 and G.722.1C are available in many Polycom SIP devices, but not yet widely available in other devices (although there are softphones that have them), although they are available as binary add-on modules for Asterisk. 3- What is the main difference between the two and is it advisable to run these over the INTERnet (not INTRAnet)? Which two are you referring to here? G.722 is frequently used over the Internet (the weekly VUC makes it available, for example), and G.722.1/C use less network bandwidth than it does, so they should be usable in the same situations as well. Whether they are advisable for you to use or not depends entirely on your network connectivity, bandwidth and packet loss situation. None of them use more network bandwidth than G.711, though, so if your network connections can already handle G.711 calls without causing unacceptable audio disturbance, you should be fine using any of these codecs as well. -- Kevin P.
