WARNING 911 Emergency Calling
Qwest 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.
Note: In TTY Mode, your phone will display the TTY access icon.
If TTY mode is enabled, the audio quality of non-TTY devices connected
to the headset jack may be impaired.
