[Blind-sysadmins] Cisco IP phone 7942

Hello, I am sorry for the off topic post, but i wanted to know if someone has any experience with the above cisco IP phone and its accessibility. The company i am working for have just roled these phones out to everyone and seeing as they have a range of features, is there a way to make this functionality accessible? The phone that has been given to us is the Cisco IP phone 7942. I know that there are third party applications that can be installed on this phone, but i would be grateful for any more information on how to go about this. Regards, Chamandeep Singh
