WARNING 911 Emergency Calling
It is recommended 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.
