[asterisk-users] "alaw = 1-2" in system.conf (dahdi) not working in UK

[Sebastian Arcus]

Hi all,

I've tried to explicitly set my two PSTN trunks/FXO lines to alaw with:

alaw = 1-2

in /etc/dahdi/system.conf. However, when I do this, all I get is loud 
intense noise on the line and nothing else - can't dial, can't make 
calls, can't receive calls. If I omit it altogether, everything works fine.

As I'm in the UK - I thought Europe uses alaw on phone lines - how come 
Asterisk seems to be using only ulaw - and alaw won't even work? Config 
examples on the Internet seem to suggest that it should work.

Thanks for any help,

Sebastian
