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 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.
