Summary:                    dnsmgr failes to match peer when SIP srvlookup is on

find a peer but it failes.

Sending fake auth rejection for device "+48607382193"
<sip:607382193 at sbc.freeconet.pl>;tag=as108407ed

when i type in console: 
dnsmgr refresh
    -- Refreshing DNS lookups.
    -- refreshing 'sip.freeconet.pl'
       > ast_get_srv: SRV lookup for '_sip._UDP.sip.freeconet.pl' mapped
to host server1.freeconet.pl, port 5060
[Feb 24 19:05:14] NOTICE[11952]: dnsmgr.c:181 dnsmgr_refresh: dnssrv: host
'sip.freeconet.pl' changed from 213.218.116.66:5060 to 213.218.116.65:5060

however after I make a call:
dnsmgr refresh
    -- Refreshing DNS lookups.
    -- refreshing 'sip.freeconet.pl'
[Feb 24 19:06:21] NOTICE[11952]: dnsmgr.c:181 dnsmgr_refresh: dnssrv: host
'sip.freeconet.pl' changed from 213.218.116.65:5060 to 213.218.116.66:5060
    -- refreshing 'sip.freeconet.pl'
       > ast_get_srv: SRV lookup for '_sip._UDP.sip.freeconet.pl' mapped
to host server1.freeconet.pl, port 5060

and incoming calls from peer are matched properly. It only happens on
every restart of asterisk till no outbound call is done. When i turn of
srvlookup everything works fine.

Something is definitely wrong here:

---
Non-authoritative answer:
Name:    server1.freeconet.pl
Address:  213.218.116.65

Non-authoritative answer:
Name:    server2.freeconet.pl
Address:  213.218.116.66
---

Unless the provider swapped A records at some point today, we are caching
the wrong address for server1.
