Attached is a config file for ser that acts just as SEMS frontend. Voicemail and ISDN gateway are configured in sems. The config file accepts signalling only from the main routing proxy (in the example running on 192.168.0.2). Username in the Request-URI of messages that are forwarded to voicemail must begin with vm+ to distinguish the messages from the messages to the ISDN gateway. Only numeric destinations are forwarded to the ISDN gateway. The main routing proxy will then forward to voicemail using this: if (isflagset(4)) { # Voicemail is running on the same server as ISDN # gateway, # voicemail is distinguised by vm+ # prefix rewritehostport("192.168.0.1:5060"); prefix("vm+"); t_relay(); }; Jan.
