Hi all, I want to configure SER and SEMS using two different instances of SER like:   [SER A]<--IP interface-->[SER B]<=fifo interface=>[SEMS] Both SER instaces and SEMS are located in the same machine. In the SER-SEMS-HOWTO there's an explanation on how to redirect SIP messages to SEMS: MY QUESTION IS, WHERE DO THESE LINES HAVE TO BE ADDED, IN THE SER_A.CFG OR THE SER_B.CFG  ( I would then change the configuration to use fifo instead of unix sockets). This is a very simple question but it will help a lot. Thank you, Llanos
