Hi,
Has anyone tried to use gnokii to send/receive SMS messages via serial or USB
with AT commands while running Asterisk?
Some of my calls have a "scratchy sound" once in a while. It doesn't seem to be
due to packet loss but some kind of interference (CPU is ok, etc.). I've
noticed some coincidence in time between this scratchy sound and the gnokii
process. I have a bash script that calls gnokii periodically to send/receive
messages. The bad audio quality does not *always* appear when the gnokii
process is up but just *sometimes*. If I stop my script, thus gnokii, it seems
that audio quality is fine overall.
What I still don't quite understand is who's responsible for this audio
problem: gnokii itself (I don't think so), the GSM radio signal nearby (about 2
meters) or the data sent through the serial port/cable.
The third explanation is the most probable but I'd like to know other people's
opinions.
Thanks,
Vieri
