WARNING: 911 Emergency Calling Sprint recommends that TTY users make emergency
calls by other means, including Telecommunications Relay Services (TRS),
analog cellular, and landline 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 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.
