indeed, this was a problem. my setup also involves PRI/FXO -> Queue -> FXS 
no SIP involved on my setup. the problem is pretty much the same as
describe by the original reporter. I'm just wondering if Monitor will fixed
the issue on my end.

By the way i haven't tried to store the recording temporarily on memory
/dev/shm then later on move to a real disk. i'll be back to this if this
setup can alleviate the situation. if the issue's has something to do with
I/O then i'm pretty sure this will fix it.

Regards,

Ronald
