Dear Daniel,

I am keeping this on list so that it can be help ful to others as well.
>>>They ask me to return back to them the data packets they send me
through.
In my opinion
                  They are sending you data packets on  some channel and you
need to reply back from another channel ie send those data packets back from
another channel(just like recieving a call from DAHDI/1 and send back by
DAHDI/2 using pri_cpe and pri_net respectively). I have not experienced with
it so if you know some thing better please add to my knowledge.
