That would be because this is the expected behavior.  The call isn't
coming from the outside caller, it's coming from the person who
transferred it.

Getting this behavior shouldn't be too hard I wouldn't think. First,
be aware that the Dial command has an option s(x) which is described:

s(x): Force the outgoing callerid tag parameter to be set to the
    string <x>.
    Works with the f option.

So if you simply transfer to a dial application with that option,
you can force the callerid to be whatever you want it to be. You can
also retrieve the callerid of the original caller and put it on your
transferring peer in a variable when starting the call. I'm not
exactly sure on the specifics of that right now, but I'm pretty sure
it should be possible. So then when you are making the transfer to
dial, you just use that variable as your argument to the s option.
