Hi Daniel
I wrote in my first patch announcing email, that i didn't test the
patched dns resolution without cache.
I only tested with dns cache.
This is the reason why i didn't recognize this problem.
You are right I made a mistake, but now it is corrected.
Many Thanks,
Misi

Hello,
I was looking to the patch and I spotted that you didn't assign
anymore a value to he variable -- next is the specific part of the diff:
- /* fallback to normal srv lookup */
- he=srv_sip_resolvehost(name, 0, port, proto, 0, 0);
+ /* fallback to srv lookup */
+ no_naptr_srv_sip_resolvehost(name,port,proto);
Shouldn't be like: he = no_naptr_srv_sip_resolvehost(name,port,proto);
Cheers,
Daniel

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!

After you had time to review it, please let me know your thoughts.
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.
