Suspended job & invalid dialing command

[Luiz Otavio Lautenschlaeger Zorzella <zorzella@dcc.unicamp.br>]

I want to know:

1) why some jobs entered in a "suspended" state at faxstat, and how to
make them alive again...

% faxstat -s
JID  Pri S  Owner Number       Pages Dials     TTS Status
1433 127 T   root 0W2392607     0:0   0:12         
1434 127 T   root 0W2321740     0:0   0:12         

2) why are there some jobs at doneq that have the status "invalid
dialing command"

1402 126 D conex- 0W2414584     0:2   1:12         Invalid dialing command

Thanks.
