IMPORTANT 911 Emergency Calling: We recommend that TTY users
make emergency calls by other means, including Telecommunications
Relay Services (TRS), analog cellular, and land line communications.
Wireless TTY calls to 911 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. The wireless industry and PSAP
community are currently working to resolve this.
