Flexible Call Offering (FCO)
* The Directory Number, Circuit-switched Voice, and Circuit-switched Voice Limit
parameters should be set to 2 to allow both analog ports to be used simultaneously.
Otherwise, if those parameters are set to 1, the ISDN line can only place or receive one
call at a time.
† FCO (also referred to as Additional Call Offering) allows you to receive an incoming call
while a dual-channel Multilink PPP call is active. If you do not want this feature, which
may cost extra, FCO is not required.
