[OpenSIPS-Users] $DLG_dir is getting NULL in onreply_route

[Ben Newlin]

Are you sure this is a sequential request? The $DLG_dir variable is only used for sequential requests as the direction indicated is relative to the initial request. [1] The direction for the initial request would always be “downstream”.
