Have Skype and Global IP Solutions (GIPS) parted ways?
Continue Reading: Have Skype and Global IP Solutions (GIPS) parted ways?Ever since Skype first launched, they have really been one of the showcases for Global IP Solutions‘ (GIPS – formerly “Global IP Sound”) codecs, particularly the wideband iSAC codec which you could argue is largely what has accounted for the great audio quality you can often get on Skype calls. Now, of course GIPS has many other customers – in fact their customer/partner list reads like a veritable “Who’s Who” of companies within the VoIP industry.

As Rich describes in his blog entry:
Once on the call I was able to easily position the three callers all around me. One could be directly ahead of me and one on either side. The computer can automatically position participants as well if you so choose.
When everyone was in place, Keith had one coworker start counting from 1 and another reciting the alphabet from letter “A.” While these two participants spoke, Keith proceeded to speak with me and the strangest thing happened.
