Without getting into a lot of detail, this will not work.  Period.   
You just can't do reliable modem passthrough with VoIP in most cases,  
some clever proprietary hacks notwithstanding.


To the extent it is possible, nobody is going to "send you the  
procedure.". This list is for specific answers to specific questions.

Not true...

You can provided you disable data compression (AT&K0) on your modem.   
Reason?  Because a codec is already compressed.  Adding compression at
the modem level to an already compressed bitstream == lost bits.  I call
all over the world all the time using asterisk/sip/ulaw with decent bit
rates.
