TIA-4953 is a standard set by the Telecommunications Industry Association (TIA) that indicates how loud a phone is. CaptionCall is proud to be the first and only captioning telephone that meets the strict amplification standards for people with mild, moderate, or severe hearing loss. This means people with different levels of hearing loss will be able to hear and understand speech better on the CaptionCall phone than on any other captioning telephone and most amplified phones.

It’s an industry standard set by the Telecommunications Industry Association (TIA) indicating how a telephone interacts with hearing aids. It measures the magnetic noise that comes from a telephone handset; this noise can interfere with hearing aids. The CaptionCall phone meets the TIA-1083 standard for hearing aid compatibility and reduced interference. Hearing aid users will experience significantly reduced interference, static, or buzz when using a CaptionCall phone. 

It varies by update, but the phone will only update when it’s inactive. 

You can change your voicemail preferences under Settings by navigating to System settings, then Voice Messages. You can find detailed instructions in the CaptionCall user guide.

You might try confirming:

  • Your internet service is working. If it is not, your phone will have a dial tone, but the captioning will not work.
  • The power cord is securely plugged into the phone and into an outlet.
  • A telephone cord is connected to the phone port and the phone jack in the wall.
  • The Ethernet cord (thicker than a phone cord) is connected to the LAN port and your modem. This does not apply if you’re using wireless internet (WiFi).
