There are two kinds of delivery reports, because I've specifically got
them turned off in my phone, but my sister still gets them when she sends
to me, so I think they're network-generated, and that means they will
only work as far as the network can tell, so if transferring to a
different network (She's on a different one than I am), she'll only know
when they're sent to my network, not to me. And I know my phone doesn't
send them back, because she has received some when I was out of coverage.

It may depend on the phone, but on my current phone yes, SMS can be sent
and received while I'm on a call. I've had that happen MANY times, and
my phone isn't one of the ones that can GSM and GPRS at the same time.

Assuming that the receipts are sent from the phone, yes, there should be.
However, if (as I suspect) they are generated by the network, there's
nothing you can do about them, but they're not terribly accurate to begin
