Does Cisco support soft phones anymore ? Does CUCM 5x & 6x support soft-phones? I mean can we migrate phones in CUCM 4x to CUCM 5x or 6x? Or do we repalce them with hard-phones / IP Communicators?
Life is good :) I'm not very familiar with the Citrix piece, but everything else should be good to go!
