asterisk users - Dec 2004 - Sometimes calls are silent

I'm setting up an asterisk server, used as a gateway to regular phone 
lines.  I've got a TDM400P card with FXO modules, but I'm only using one
to test.

When I make outgoing calls, occassionally it seems like the incoming 
audio is switched off.  It will work fine for several calls, and then 
for several more calls the incoming audio will be silent.  The other 
party can still hear me, I just can't hear them.

I'm using fxs with ks.  I've tried it w/ echo cancelling both on and 
off.  Anyone else have this problem?  It never happens in the middle of 
a call, either.  The call either has sound or it doesn't have sound.

I'm using Firefly for my SIP phone, but I don't think it's an issue
with
the soft phone.

Thanks!

Jon

Hi Jonathan, 
can you be a little more clear ? What is your test configuration? How
do you expect to have voice if you use only one FXO of the card (maybe
you use regular phones too ..)
