[cisco-voip] Media Gateway issue with NTE

[tele]

some additional info about my issue:

The RFC3660 talks about the MF package

2.9 - Media Format Parameter Package

   Package Name: FM

The package is called FM.

In the Cisco media gateway i have only a "MF" package and not a "FM" 
package.
So i think there is no FM package for Cisco MGCP.

*mf*-*package*—MF package. Events and signals for multifrequency tones 
(MF) relay.

i don't know if with a FM package support i can solve my problem.
