Is there a reasonably easy way to increase the volume on a DAHDI channel? The VOIP phones in the house work OK, but for the phones connected to DAHDI channels on a Digium TDM400P card, the volume is very low and it's hard to hear if there is any background noise at all. If this is documented, point me to where and I'll gladly do my reading. Thanks, --Greg

Txgain/rxgain in dahdi.conf control this - you will have to restart asterisk
on each change to test the values to set to your liking - my settings are
rxgain=8.0
txgain=4.0

Is there a reasonably easy way to increase the volume on a DAHDI
channel? The VOIP phones in the house work OK, but for the phones
connected to DAHDI channels on a Digium TDM400P card, the volume is very
low and it's hard to hear if there is any background noise at all. If
this is documented, point me to where and I'll gladly do my reading.
Thanks,
