For many years the telco's supported a ringback code so as to test a telephone's ringer and the line. The code changed over time.
In recent years it was 113+4d (the 4 digits of the phone number). One then flashed and hung up, and the phone would ring. But that is no longer working.
Would anyone know the current ringback code?
Thanks!
[public replies, please]P.S. Are there any other 11N codes? (ie. 112, 117, etc.?)
