Yesterday I noticed something strange happenign one on of our servers. Calls were being sent to servers within our VoIP platform by OpenSER without (as far as I can see) really being handled according to our OpenSER configuration.
What I forgot to emntion that the rewrites later in the config should have matched, but they are not being executed which suggests to me that an earlier statement in the config resulted in the message being sent directly to the server instead of first following the configuration.
