Even though the ilbc codec likes multiples of 50 for its frame size (Is 
this right?), I was under the impression that asterisk broke everything 
down to 20ms slin samples internally, unless it was just directly 
bridging two similarly-codeced channels.  I would imagine that Sanjay 
meant zaptel hardware anyway, as the SIT is an in-band pattern meant for 
our ears.  (I think that SIP would simply return  a cause code 
out-of-band describing WHY the call failed, but would not pass any RTP 
audio.)
