hi everybody, You can see attached my conf files for ser, ser-sems and sems. I run two instances of ser : 1. the first on port 5060 2. the second which is the sip stack for sems, on 5070 My conf files show that when for example i call 101 or 102 , the call is directed to sems, but the debug of my 2nd ser shows this : 2(8658) write_to_unixsock: Error in connect: Connection refused 2(8658) ERROR:tm:t_write_unix: write_to_unixsock failed 2(8658) write_to_unixsock: Error in connect: Connection refused 2(8658) ERROR:tm:t_write_unix: write_to_unixsock failed Probably these is some kind of problem with my unix socket configuration in my conf files... can anyone help me ??
