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.
