Hi, I want to mantain independent domains in OpenSer. In my case I've a OpenSer with a single DNS A record and various CNAME (I still don't want to play with SRV and so).
so:
DNS A = openser.domain.org CNAME = sip1.domain.org CNAME = sip2.domain.org
And I want users of sip1.domain.org and sip2.domain.org, as independent groups.
I just want to avoid SIP interdomain messages, so 200@sip1.domain.org CAN'T invite 300@sip2.domain.org even if he does authentication.
I've loaded "domain" module and use "is_uri_host_local()" and "is_from_local()" functions, but for now I only used one domain.
My question is very general: for implement (or avoid) interdomain comunication, do I need to use the "domainpolicy" [1] module? I've read its doc and know it's based in 3 drafts [2][3][4], but all of them seems to be based in the complex NAPTR record and so. Is it the way?
I think I could just compare the FROM domain with the TO domain in order to avoid interdomain communication, but of course I'd like in the future the possiblity of allowing some domains to contact some other domains. Is then "domainpolicy" the solution I should learn?
Any other doc about it?
Thanks for any help.
