Sure, why not.
The configuration depens a bit on what you want exactly and what is on the other side but here's an example:
username REMOTE1 password PASS1
interface Serial0/0:15
no ip address
encapsulation ppp
no logging event link-status
dialer pool-member 1
isdn switch-type primary-net5
no cdp enable
ppp authentication chap
ppp chap hostname CENTRAL
!
interface Dialer1
bandwidth 64
ip unnumbered FastEthernet0/0
encapsulation ppp
dialer pool 1
dialer remote-name REMOTE1
dialer string 5551234
dialer-group 1
no cdp enable
!etc. (one Dialer interface per destination)
dialer-list 1 protocol ip list 100
access-list 100 deny udp any any eq rip
access-list 100 permit ip any any
You can customize the Dialers in various ways, e.g.
ppp authentication chap callin
to prevent that the router dialing out requests authentication from the BRI router.
ppp chap hostname ALTERNATIVENAME
to change the name the routers presents itself as in ppp,
ppp authentication pap callin
ppp pap sent-username USER password PASS
to use pap authentication instead of CHAP,
etc.
If you need specific help, let us know.
BTW, there is no limit of 15 destinations, you can define more Dialer interfaces and the router will be able to support 30 simultaneous calls to different destinations.
