How to bond two T1's into a single 3Mb connection point to point with VOIP and Normal Data Traffic QoS

Hello, thank you for your assistance.

We have two T1's from Location A to B, and a Cisco 1841 Router with a Dual T1 WIC at each location. Our requirement is to have the two T1's bonded into a 3Mbps pipe. If one T1 shall go down, the link should still stay up on the other T1 line.

Since our phones which are VOIP based, are going to be chatting over this connection I need to make sure that call quality is exceptional and stable. Do I need to use QoS? Should I use MLPPP?

What is the best way to accomplish this? I am not allowed to change the routers, I must keep the 1841's one at each location.  I would really appreciate a concrete example or cisco config as I have not done this before.

Thank you very much!
