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

[Nick Matthews]

No IOS will solve this problem. You have to engineer your design to not
require MTPs. Do you know why you have MTPs enabled? It's commonly an
interop problem or a DTMF mismatch (RFC 2833-> out of band (h245 alpha,
sccp, mgcp ntfy, etc).
