I have a client who would like to install a TTY device in their office.
They have a Asterisk PBX with a CBeyond T1 to the PSTN, and the system
uses the CBeyond SIPConnect facility for PSTN voice calls.
The TTY device would connect with a TDM10B (FXS) card and have its own
DID number.
I believe the protocol between the calling TTY and the local TTY is FSK.
In any case, would two TTY devices be able to communicate over an RTP
stream using g711?
Or should the TTY device be attached to a POTS circuit away from the PBX?
Thanks,
