[cisco-voip] FXO disconnect problem - telco side?

[Tom Storey]

Ok, I must be missing something bleedingly obvious here...

Doesnt that document refer to the Cisco *recieving* a disconnect  
signal in order to tell it to hang up? Or should the Cisco also be  
generating the same sorts of signals to tell the telco to hang up  
aswell?

My issue relates to the later, in that the telco dosnt appear to be  
recognising a disconnect upon the Cisco's FXO going on hook.
