ISDN B channel allocation for Dialers

How can I provide always one B channel for both Dialers and two B channels for one Dialer if necessary?

Router1

interface BRI0

encapsulation ppp

dialer pool-member 10 min-link 1

dialer pool-member 20 min-link 1

!

interface Dialer10

encapsulation ppp

dialer pool 10

dialer max-link 2

!

interface Dialer20

encapsulation ppp

dialer pool 20

dialer max-link 2

Is this configuration correct?

Since you have configured min-link as 1 under the BRI for each dialer, both B-channels have been reserved for outgoing calls, and you will not be able to receive any incoming calls using this BRI interface. And, because you have 'dialer max-link' as 2 under the dialer interfaces, they will use maximum of 2 links together for incoming/outgoing calls.' See if this helps you :

Last time I checked (about two years ago), dialer max-link only applied to outbound calls and could not be used to control incoming calls. Has this behavior been changed or is the allocation of all channels a special case?
