[Asterisk-Users] Citrix

[Rod Bacon]

Ultimately, Citrix will be a recognised player in the VOIP space. The fact 
that they acquired Net6 last year should be a reasonable indicator.

My comments were based on my personal experience with ICA over the last 10 
years, and also based on where ICA and Metaframe are right now.

Indeed, there are a number of unused channels in the ICA protocol that will 
(potentially) facilitate the carrying of voice data with the appropriate 
prioritisation. These were originally added to allow such things as 
streaming audio and video (and one would assume, VOIP).

Keep in mind that the nature of the ICA protocol has always been fairly 
asymmetrical. There was never really the need to send much more than 
keyboard/mouse data back to the server. Historical movements of Citrix into 
the multimedia arena have been reasonably forgettable... just google for 
info on the Citrix Videoframe product.
