Have a look at Bug 3813 and see if it fits with your experience. I 
suspect the echo cancellor and it would be interesting to see if the 
X100P has the same problem.

I would encourage anyone who has been experiencing erratic or non - 
functioning busydetect to check it also.

With the reliability I am now seeing with the latest FXO modules, I 
finally think I now have a production quality hardware setup. The 
inability to be able to fully adjust TX and RX gains on the FXO module 
to balance line loss to the PSTN is the only showstopper to me 
recommending the TDMXX solution for small setups.
