It's a tele typewriter. It's for people with hearing/speech difficulties.
It means that the phone is compatible with a TTY (Tele Typewriter) device for people with hearing difficulties.
The symbol you are most likely talking about is the TTY symbol, which would appear in the menubar of your phone. It indicates that TTY is enabled for iPhone users who are normally deaf or hard-of-hearing. If you do not want this feature to be enabled, simply go to your Settings app and tap on Phone, and then tap on the TTY slider to "Off."
The TTY option is turned on. you can turn it off in the setting>phone>TTY
There are no official statistics available to support how many failures the TTY would have out of 10 trials. Suffice to say however, that how reliable the TTY device would be depends greatly upon the telephone network provider. As long as there is reasonable coverage and the phone lines remain intact, the TTY device should work flawlessly.
Settings, phone, tty off. if wnt turn off, call Apple Support 800-694-7466. Check out apple.com/support/iphone for helpful information.
There are phones that have something called TTY, also called TDD, a service for the deaf and hard of hearing. See the Related Links for more information, and call your local telephone company about how to get TTY or TDD service.
It depends on the rest of the message... The letters tty could mean talk to you, and hco could mean hey come over. However these are just two examples my brain came up with when I saw the question !
I think it is TTY,its for deaf people,you can turn that option off

Yes, the TTY is very successful. The TTY uses text to send a message over the telephone wires. This is used for people that are deaf, speech impaired or have trouble hearing to converse with others.
This might help you.... go on settings and tools, then go on call settings, then tty mode and choose one of them expt for off... i know it doesnt work for both of them but you might wanna try out tty full i dont know what that does but try it and see what happens
