Inbound SIP calls to username-inboundroute@pbxes.org (like alexburke-5556667777@pbxes.org) go to the default inbound route of "/" instead of to the specific inbound route desired (5556667777 in this case). This still happens if I rename the inbound route 5556667777 to alexburke-5556667777.
This is needed for ENUM etc to work properly.
I tried "Submit & Start" to reset the PBX, and I also migrated it from one server to another (and back). Neither one helped.
