klaus,

if you want to support domains in route headers, then you need to do naptr and srv lookups for the domain when handling loose routing. it is not enough to compare the domain to the ones domain module knows about. domain in route header may namely be anything as long as it resolves to your proxy.

well, if foo.bar decides to have the DNS name pointed to IP address of a server which doesn't know about it, that seems to me foo.bar's problem and I'm happy to leave it there.

I don't see issues if the domain names are condigured in reasonable administrative context though.

for this reason, i don't like the idea of domains in route

...

headers. it hurts performance far too much.

Well I don't like the domain names in route header either, but I think the question is how to deal with client that use it -- drop them on the floor?

I also do not like to configure openser all possible hostnames as alias

• but it is not uncommon that the SIP domain is in the pre-loaded route
• at least most exosip based clients do that. Thus, having support for

those clients is IMO useful.

I think configuring those domains using the domain module would work just fine, only if the rr-module would leverage it :-) I think that should be addressed. Sounds like something that should be filed on JIRA.
