[asterisk-dev] send_digit mechanism in ast_channel_tech

[Paulo Garcia]

Hi,

my custom channel has a function called xx_digit associated to send_digit
field from ast_channel_tech. In my configuration file, I have an option that
allow to my card generate the dtmf or not into xx_digit function.

When I turn off this option, the dtmf is still generated, apparently by
asterisk. Do I need to return some special value to avoid dtmf generation by
asterisk?

Thanks in advance!
