[Serusers] Questions on using ser.cfg version 0.9.0 for call forward/busy/noanswer

Dear ALL: I think it is a very good chance to study Paul's ser.cfg file. I use the 0.9.0 sample cfg and try to implement a call forward, busy forward, no answer forward function. But I got a 503 message when I use make a call from UA 1011 to UA 1022(registed on the same ser) with callforward to a PSTN . But I have no voicemail option supported. So I must modify it. In usr_preferences table: username domain attribute value ------------------------------------------------------------------------------------------------------------------- 1022 ser.xxx.net.tw donotdisturb n 1022 ser.xxx.net.tw voicemail n 1022 ser.xxx.net.tw anoncallrej n 1022 ser.xxx.net.tw callidblock n 1022 ser.xxx.net.tw callfwd 0939749xxx(a)ser.xxx.net.tw 1022 ser.xxx.net.tw fwdnoanswer 0939749xxx(a)ser.xxx.net.tw 1022 ser.xxx.net.tw fwdbusy 0939749xxx(a)ser.xxx.net.tw In grp table: username domain grp --------------------------------------------------- 1022 ser.xxx.net.tw int 1011 ser.xxx.net.tw int I don't know where to defind the 'dom' and 'int' or '-' setting at DB table. What is its table name? domain ==> ser.xxx.net.tw (the same as caller and machine) When I test this call forward, a UA 1011 call to 1022. It It should be forward to a PSTN and use route(3) or route(6). But when I do it, it seems failed at lookup("aliases") and lookup("location") function.

Also the error message "error: mediaproxy/sendMediaproxyCommand(): can't connect to MediaProxy" always displays at log file whether the call is connected or failed call.
