I am using a device that acts as a door speaker system with 'ab' interface. It works quite well, but as the phone inside the house is hung up, the busy tone is received by the device but not detected. So the device didn't hung up.
The company tells me, that I have to use the european signalling standard by the SPA 2102 to get it working.
I found lot of settings, but changes doesnt help.
Here the current setting for the Busy tone: 440@-10,440@0;10(.125/.125/1+2). The device can detect busy tones between 380Hz and 480Hz and need a signal with 500mS on, 500mS off.
Where can I get a documentation about the configuration string syntax and semantik?
I guess now, that this settings effects only the detection of signals by the SPA 2102, but if this is correct, where can I set the output signals??
