For several reasons and the sake of older telephones working properly, I’d need the Advice Of Charge (AOC) information transmitted to the telephone connected to FXS.
These informations are sent using a pulse at 16khz or 12khz depending on the country.
To configure this, as this information can only be locally generated a textfield containing the config data. Example of config data:
The syntax is a series of semicolon separated AOC descriptions:
- frequency of tones (12k or 16k allowed only)
- Interval:Number of repeats
2 can be repeated multiple times
AOC generation starts on on call connect.
16khz, charge one unit every 30 seconds, until end of call
16khz, first two minutes are charged each with a puls, then charge one unit every 30 seconds until end of call
12khz, first 300 seconds are charged with 1 units every 30 seconds, after this nothing will be charged anymore
12kHz, Charge one unit every minute
Having that feature would be a huge plus over other manufacturers and help a lot of people to solve some serious issues they have now, There was a manufacturer who implemented the functionality in sort of the described way but stopped supporting it, when a new HW release was launched.
Maybe you’d like to launch this feature with your new V2 HW generation.
