[SR-Users] DNS Host-Names in Via and Record-Route for more redundancy?

Hi Folks

We use two 'core' instances and two 'registrar' instances.

The pairs sync their information (Dialogues + Locations) via DMQ.

But I noticed that they record the Via and Record-Routes by IP
addresses. So I guess if one fails, signaling would not automatically
switch to the remaining host as the IP of the failed one is in the
header, right?

So, is there a way to put a DNS resolvable host-name in the Via and
Record-Route header, so that DNS round-robin would make sure requests
reach the available server if one of the pairs fails?

Mit freundlichen Grüssen
