Summary:                    TDM400P FXO when configured for alaw fails to
dialout
Description: 
In /etc/dahdi/system.conf selecting alaw=35 causes the FXO to fail
dialout.

All that is heard is constant ~1000Hz square wave, this estimated.

Using mulaw=35 the line works fine.

This is not new, also happens on our production box which is Asterisk
1.6.0-rc6 with DAHDI-2.0.0-rc2

mtucker: I think this is your answer.
The file /etc/modprobe.d/dahdi should look similar to below;

# You should place any module parameters for your DAHDI modules here
# Example:
#
# options wctdm24xxp latency=6
options wctdm alawoverride=1 boostringer=1
