After testing with the usrloc and registrar settings for use_domain to "1", I have discovered a problem. Calls routing in from my gateway are not routing to the registered UAs. The registered UAs are not in the same domain as the gateway and I believe the modparam setting is preventing it. What is the solution to this dilemma? Aliases? If so, for whom? Do I add alias domains for the UAs to match the gateway domain? Or do I add domain aliases for the gateway UA. Thanks! F __________________________________________________ Do You Yahoo!?
