That is where I really appreciate being able to get a decent read-out of line

Any nodelisted system can request the magic name STAT to get a similar 
read-out performed on-the-fly, and first time bbs callers +61 8 8370 2365 can 
download the file CALL.NEW to see their connection quality also.
Having such information helped me to get Telstra to upgrade their network 
echo cancellers to work properly according to G.165.
The current call information is also available from the Motorola Codex 326X 
LCD front-panel display.
