Both sides have to be willing to negotiate a port. Maybe your
handytone has its own restrictions on RTP ports? As you now know,
Asterisk doesn't care as long as you specify a range in rtp.conf.

1000-2000 must be a typo as ports <1024 are reserved and privileged.

There's no standard - there are several different conventions adopted
by different vendors, though.
