[Asterisk-Users] DISA disconnects

[Min Hwan Chang]

DISA is currently disconnecting when I dial 8888 to access DISA.  
Below is my extensions.conf file from A at H and some lines which shows
the disconnect. Should DISA be loaded as a module in modules.conf? 
When I do a 'show applications' i see that DISA is there.  Help!
