Issue Description

As the title says. Suppose you have a resolv.conf:

search anything.something.example.com something.example.com example.com
nameserver 10.0.0.1
options ndots:4

And an asterisk config snippet like:

[reg1]
type=registration
transport=transport-udp
client_uri=sip:pbx@nothing.everything.local
server_uri=sip:registrar@nothing.everything.local

Then asterisk will only try to resolve nothing.everything.local, and for example, not nothing.everything.local.example.com, like the underlying operating system would. While the workaround for this is easy, this causes confusion, especially in kubernetes environments. This way, the registrartion will be shown as rejected, while asterisk just couldn't resolve the domain properly, while everything else in the system could.

Relevant log output

No response

libunbound ignores those settings. We would have to implement this behavior ourselves.
