[asterisk-users] PJSIP sending RTP to private address

My phone is located behind a NAT,
Asterisk 16 is on a public IP.
PJSIP has the config below:
disable_direct_media_on_nat = yes

But when I send a call I see the RTP being sent to my private address, vs
the public IP. This only happens when Asterisk  has dialed the call to
another carrier. If instead of Dial I choose Answer() and MusicOnHold, then
the RTP gets shipped to the right address.
This is a sample of the erroneous behavior:
Got  RTP packet from    XX.XX.XX.XX:17510 (type 00, seq 024786, ts 017440,
len 000160)
Sent RTP packet to (type 00, seq 010736, ts 017440,
len 000160) is my private address.
What am I missing? Should I open a bug?
Asterisk should never, ever send RTP to a private address when Asterisk
itself is on a public IP.
Before you ask, the dialplan is 3 lines,
'_X.' =>          1. NoOP()
                    2. Dial(PJSIP/${EXTEN}@carrier)
                    3. Hangup()
