[Serusers] error message when attempt to call transfer

Hi, When I attempt to do call transfer, I get the following error message: Jul 4 11:49:46 localhost /sbin/ser[1992]: *** entering route[3] *** Jul 4 11:49:46 localhost /sbin/ser[1992]: ERROR: tcp_blocking_connect: SO_ERROR (111) Connection refused Jul 4 11:49:46 localhost /sbin/ser[1992]: ERROR: tcpconn_connect: tcp_blocking_connect failed Jul 4 11:49:46 localhost /sbin/ser[1992]: ERROR: tcp_send: connect failed Jul 4 11:49:46 localhost /sbin/ser[1992]: msg_send: ERROR: tcp_send failed Jul 4 11:49:46 localhost /sbin/ser[1992]: ERROR: t_forward_nonack: sending request failed Jul 4 11:49:46 localhost /sbin/ser[2000]: *** entering onreply_route[1] *** Jul 4 11:49:46 localhost /sbin/ser[1992]: ERROR: tcp_blocking_connect: SO_ERROR (111) Connection refused Jul 4 11:49:46 localhost /sbin/ser[1992]: ERROR: tcpconn_connect: tcp_blocking_connect failed Jul 4 11:49:46 localhost /sbin/ser[1992]: ERROR: tcp_send: connect failed Jul 4 11:49:46 localhost /sbin/ser[1992]: msg_send: ERROR: tcp_send failed Jul 4 11:49:46 localhost /sbin/ser[1992]: ERROR: t_forward_nonack: sending request failed Is there anything I need to configure on the routing script to be able to do call transfer? Thanks in advance. Regards, Chia
