CallTTY is an alternative way to facilitate communications between TTY/TDD devices which are generally used by the deaf to make telephone calls. CallTTY does not require a TTY modem, but instead uses your current sound card, alone with a modem hooked up to a telephone line.
CallTTY is licensed as Shareware for the Windows operating system / platform from modem and telephony software and can be used as a free trial until the trial period ends (after 30 days). The CallTTY 2.35 demo is available to all software users as a free download with potential restrictions and is not necessarily the download of the full version.
Compatibility with this sound communication software may vary, but will generally run fine under Microsoft Windows 10, 8, 8.1, 7, Vista and XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from Dxsoft.
We have tested CallTTY 2.35 against malware with several different programs. We certify that this program is clean of viruses, malware and trojans. [Read more]
