t_write_req appeared in SER version 0.9, in 0.8.12 it had another sintax, which I don't remember now...take a look at older posts or the tm module interface to find it out.. Samuel. Unclassified. Hi all, in the SER-SEMS-HOWTO, the next paragraph appears: Redirecting the messages is a very simple operation. You just have to call the t_write_unix() (or t_write_req()) function from the 'tm' module, which you have to load. In ser.cfg routing: t_write_req("/tmp/am_fifo", "voicemail") But in my tm module (SER 0.8.14), t_write_req doesn't appear, and so if I add that line I get an error of configuration. What's wrong with this? Please help, Llanos
