Warning: 9-1-1 Emergency Calling
It is recommended that TTY users make emergency calls by other means, including
Telecommunications Relay Services (TRS), analog cellular, and landline communications. Wireless
TTY calls to 9-1-1 may be corrupted when received by public safety answering points (PSAPs),
rendering some communications unintelligible. The problem encountered appears related to TTY
equipment or software used by PSAPs. This matter has been brought to the attention of the FCC,
and the wireless industry and the PSAP community are currently working to resolve this.
