[Dnsmasq-discuss] dnsmasq and freenum.org issue

Hi,

I've been using dnsmasq for a while now and love it.  It's perfect for my
home LAN setup.  I have one issue, however, trying to use the services of
freenum.org.   Forgive me, but I'm not well versed in DNS so I may not
explain the problem that well.

As I understand it, freenum essentially uses DNS to turn a "phone number"
into an SIP url (or a SIP url regular expression).    It uses NAPTR
records, for which I understand support was added in 2.43.  I'm running
2.45.

Dialing a "freenum" number works from my freeswitch installation when
using an outside DNS server, but when I point it to my local dnsmasq, it
does not.   Doing a "dig xxx.freenum.org NAPTR" command against dnsmasq
and the outside server shows the same thing, except that dnsmasq sets the
aa flag.

Here is the output from dnsmasq -d:

dnsmasq: query[A] 4.3.2.1.256.freenum.org from 192.168.1.xxx
dnsmasq: forwarded 4.3.2.1.256.freenum.org to 216.218.159.179
dnsmasq: query[A] 4.3.2.1.256.freenum.org from 192.168.1.xxx
dnsmasq: forwarded 4.3.2.1.256.freenum.org to 216.218.159.179

Which doesn't mean much to me.   I'm not sure how best to debug this, and
would appreciate any suggestions.

Thanks!
