[cisco-voip] Cisco Call Manager RBT Problem with AS5400 MTP Device

[He-Man]

Yes, I have already know , but we are going to use our actual devices 
unlike any other 28xx, 38xx routers. So we are going to use this 
configuration ; Sip + G.729 + Prack mode Enabled for RBT problem.I will 
send the results of this lab Nick.If you have any other idea, you can share.

Thanks.
