Actually your router is not correctly configured for multilink PPP. After the first B-channel connects, the CALLING router again dials the same number. The switch at the remote end, closest to the CALLED router recognizes that the first B-channel is busy, and transfers the call onto the second B-channel, and thereby makes bundling possible.

The following link will help you:
