Don't forget to create a multilink-group to "bundle" the interfaces. Here's an example I pulled from the Cisco website:

Configure the multilink group interface
!
interface Multilink1
no ip address
no shutdown
no cdp enable
ppp chap hostname group1
ppp multilink
multilink max-fragments 1
multilink-group 1
bridge-group 1
! Configure the individual serial interfaces
!
interface SerialDS1 1
no ip address
encapsulation ppp
no shutdown
no fair-queue
ppp chap hostname group1
ppp multilink
multilink-group 1
!
interface SerialDS1 2
no ip address
encapsulation ppp
no shutdown
no fair-queue
ppp chap hostname group1
ppp multilink
multilink-group 1
!
interface SerialDS1 3
no ip address
encapsulation ppp
no shutdown
no fair-queue
ppp chap hostname group1
ppp multilink
multilink-group 1
