Errr...no...this is wrong. Skype uses ISAC from Global IP Sound. iLBC is something different see http://www.globalipsound.com/solutions/solutions_Codecs.php One of the reasons Skype sounds good is that its a closed system and so can leverage a wideband codec. Instead of the normal 8khz sample rate it uses 16khz. That makes for clearer sound. Since ISAC is a proprietary relative of iLBC its jitter compensation is also very good. My understanding is that Asterisk cannot presently use any wideband codecs as it is hard coded to the 8khz sample rate at its core. Adapting Asterisk to wideband capability has been discussed but will be a huge amount of work. Further, only if you know that the calls will stay wideband end-to-end will the benefits of wideband be apparent. That means no PSTN segments.
