Re: [OpenSER-Users] Multidomain and in-dialog REFER auth issue

Hi, I've a multidomain OpenSer and I want to allow REFER (with authenticacion before) just in calls between users of same domain, but it's quite complex: - userA(a)domainA.com INVITE's userB(a)domainB.com. - During the call userA(a)domainA.com does an in-dialog REFER. Because the REFER is in-dialog the message is like: -------------------- REFER sip:userB@80.98.123.23:5060 SIP/2.0 From: sip:userA@domainA.com To: userB(a)domainB.com Refer-To: ... ... -------------------- How can my OpenSer know which domain this REFER goes? of course the "To" header is not valid at all. Could be a solution a SQL query to "location" table looking for the URI (sip:userB@80.98.123.23:5060) and getting the username and domain of this? Any other option? Thanks a lot.
