I'm getting the following messages when a call is answered by a SIP

For a Cisco 7940 line, I have the following sip.conf entry:
[desk2]
type=friend
username=desk2
secret=xxx
host=dynamic
dtmfmode=rfc2833
context=international

The Asterisk system faces the Internet on a public IP. The phone is
behind NAT.
Asterisk version is 1.0.7.
It has nothing to do with DTMF. It is getting a few rejected rtp frames
from the kernel 'sendto' function immediately after the call is
answered. Does anyone offer some insight?

After answer, a few rtp frames are being sent from sip_write to the
NATed address of the phone (192.168.1.43) and are being rejected. After
that, rtp frames are correctly sent to the public address of the phone's
firewall, and the conversation is normal.
Can anyone offer some insight? Do I need to move to asterisk-1.2 before
I go any further?
Thanks
