NOTICE: 911 Emergency Calling
Sprint recommends 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. This matter
has been brought to the attention of the FCC, and
the wireless industry and PSAP community are
currently working to resolve this.
