[OpenSIPS-Users] B2BUA/Top Hiding in 1.7 trunk

[ddgiants]

Use a db for which piece? I use a db in my larger config in which opensips
uses mysql to lookup source ip and carrier id, trunk group etc then hits a
redirect server which then sends back a 300 multiple. I am having same issue
with that and that uses db. That is what made me test with a generic version
of b2b top hiding config. So maybe it's a particular piece of the messaging
I need to use db? Below is my config I realize I never posted.
