[cisco-voip] CM 3.3(4) adding hardware MTP and CFB with same MAC

[Andrew Dignan]

Been so long since I added a hardware cfb and mtp instead of the enhanced
IOS cfb/mtp.

I am trying to add a hardware cfb and mtp.  The problem I am having is
that obviously I will have the same MAC address for both because it will
be the interface sccp is associated with.

I can add the CFB but when I try to add the MTP with the same mac I get an
error a device with the same MAC exists (CFB11111111111).  Shouldn't they
be different because its prefixed with MTP?  What am I missing?
