I have better understanding of dst_uri and ruri learned from another

it be useful to save and load both in functions avp_write and
avp_pushto? That's the problem I ran into at
http://mail.iptel.org/pipermail/serdev/2005-August/005339.html. I
tried to send a call to two users by loading both their locations. I
first change ruri to user 1, lookup, avp_write to save it. Then I
change ruri to user 2, lookup, avp_write to the same avp. At this
time, the avp has both users' location. But when I avp_pushto the avp,
it only load the ruri, not dst_uri. So the natted UA can't receive the
call. This problem can be solved if avp_write and avp_pushto save/load
both dst_uri and ruri.
you can backup the dst_uri (via avp_printf() ) but you cannot restore it
at this moment. avp_pushto() has to be extended to support it. I am
going to add a few new pseudo-variables in a few days (as discussed on
the mailing list) and try to update avp_pushto() as well.

That's right. If all addresses are in a list of
avps, i can use
avp_check to check 'ne' to verify.
one more thing - you should check dst_uri and not RURI - RURI may be the
private addr when the dst_uri is the public IP.
Thanks,
