One problem I can imagine is that the two sample clocks -
the one used by Jack and and the 8 kHz one used by the
telephone interface) are independent and resampling 
will have to adapt to any errors. But you mentioned
a resampling library before, maybe this takes care of
this. The same problem would exist with any audio 
interface (ALSA, OSS) used by Asterisk.
