In my DNS server, there are only AAAA records for any nodes. My test topology is as following:
-----+---------+--------+------ | | | siphone1 openser siphone2 (UA1) (UA2)
For the testing procedure, I only use domain name of the URI. When UA1 invited UA2 via openser, openser only ask A record of UA2. There are no A records in my DNS server! So, openser then replied 476 Unresolvable Destination message to UA1.
In normal conditon, if there were no such name of A record, it should ask AAAA record instead. But why OPENSER only ask A record?
