Hi,
I'm having problems connecting to a videoservice at seevia.no, because
they have no NAPTR nor _sip._udp.seevia.no entry. They do have for
tcp and sips:
% host -t NAPTR seevia.no
seevia.no has no NAPTR record
% host -t SRV _sip._udp.seevia.no
Host _sip._udp.seevia.no not found: 3(NXDOMAIN)
% host -t SRV _sip._tcp.seevia.no
_sip._tcp.seevia.no has SRV record 1 0 5060 vcse.vcn.no.
% host -t SRV _sips._tcp.seevia.no
_sips._tcp.seevia.no has SRV record 1 0 5061 vcse.vcn.no.
% host -t A vcse.vcn.no.
vcse.vcn.no has address 85.19.200.18
vcse.vcn.no has address 62.92.46.211
% host -t A seevia.no
seevia.no has address 93.89.34.42
Ref an old thread on sr-dev,
<http://lists.sip-router.org/pipermail/sr-dev/2012-October/016969.html>
this should have been fixed by
<http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=63ef5f0edcfebe86cffe7489f3524186ed3400d4>.
From tcpdump:
65177+ NAPTR? seevia.no. (27)
65177 0/1/0 (86)
31896+ SRV? _sip._udp.seevia.no. (37)
31896 NXDomain 0/1/0 (96)
54304+ A? seevia.no. (27)
54304 1/2/2 A 42.93-89-34.enivest.net (119)
Trivial to see it does not attempt to lookup anything after a NXDOMAIN
for _sip._udp.seevia.no.
% host -t A 42.93-89-34.enivest.net
42.93-89-34.enivest.net has address 93.89.34.42
Any idea why my INVITEs are being sent to 93.89.34.42
instead one of vcse.uio.no's IPs?
My dns settings:
use_dns_cache=on
use_dns_failover=on
dns_try_ipv6=no
dns_retr_time=1
dns_retr_no=2
dns_use_search_list=no
dns_try_naptr = yes
dns_srv_lb = yes
