It is complete and working patch.
If there are no NAPTR records to a domain, then according to the local
protocol preference it orders protocols and it tries to resolve SRV
records according this ordered list. If there is no order then the order
is udp,tcp,tls,sctp,..
SRV records are resolved in order Kamailio dns protocol preference.
My algorithm picks and returns with the first protocol resolvable SRV
record, so it sets from SRV the port and protocol.
(Of course if there are no SRV at all then it fallbacks to host
resolving so dns "A" record.)
It is big step forward comparing to current Kamailio behavior where it
is using strictly udp only and after it stops searching SRV records at
all, and go for "A" record!
As i wrote in my patch announcing email it is a step further on the way
to conforming with RFC3263, but my patch not handling fallback if there
are SRV-s for multiple protocols in DNS.
In such case only and only if the first protocol is temporary not
available or fails we are not falling back to other protocol but falling
back to host resolving so "A" record (and/or AAAA).
Can you send meg the iirc message what was there exactly?
Is there any other problem in it?
I guess no just what i explained above.
I am eagerly waiting your review and comment.
Thanks in advance!

unfortunately I had no time to look at it yet. Hopefully I will find
some soon.
Btw, is it complete? IIRC, I saw something like it still has to be
extended.

After you had time to review it, please let me know your thoughts. Hi,
I made some progress. As I stated before, I made a patch and
submitted to git branch misi/dns_srv.
I tested with dns cache. It works for me.
I made it also available for case if "no dns cache" is used too,
but it isn't tested yet.
Please review my commit, and let me know if any corrections needed.
if nobody does
it meanwhile, I can look over it next week and also
check properly what's all about this discussion, currently being out
of the office.
