Busy Tone Detection Tune

General Help
1

Hi,

I have a freepbx running on a raspberry pi as a GSM Gateway.

Sometimes (1 in 5) when I make a call, asterisk interprets the calling tone (long bip with short pause) as a busy tone (short bips with short pauses).

Is it possible to tune it or maybe disable the busy tone detection?

Thanks

If you use the dahdi channel driver then you can tune

busypattern=500,500 ;by default.

and

busydetect=no

in chan_dahdi.conf

If it is a SIP gateway then this does not apply,there is no busy tone detection in the SIP channel driver as it is unnecessary.

Sorry for my ignorance. I forgot that it totally depends on the chan module that I’m using.

I’m using chan_dongle (my box is a simple GSM gateway).

Thanks
