[SR-Users] Using a single virtual domain in a multi-domain setup

[Rhys Hanrahan]

HI All,

Just to add I've also tried adding multiple alias= definitions, but have
the same issue - kamailio says "user at fqdn" not found in usrloc when doing
lookup(). Maybe I need to modify my lookup() call to use a hardcoded URI?
But I haven't seen any examples where this was required for multidomain
setups.

Would really appreciate some guidance as I'm quite stuck on this.

Thanks!
Rhys.
