[SR-Users] Kamailio Asterisk integration with docker DNS Problem

[Amir]

I do not have a DNS server, Docker User-defined networks has it's own built
in DNS server,
The problem is when I stop a container its DNS record would be deleted and
therefore kamailio server could not check server health.
I think if I could tell kamailio server that IF you did not find a DNS
record it means that a server is down my solution would work.
