Hi All, I'm setting up the cpl-c module. On invite I'm calling cpl_run_script("incoming", "force_stateful"), and I'm getting no transaction found. If I add a t_newtran() before the call ser crashes. I have played with is_stateless and is_statefull all with similar results. Below you will find version, ser log with and without the t_newtran(), the CPL I'm testing with, and my config. Is my t_newtran() badly placed? I'm surprised I managed to actually crash ser with this.
