[Freeswitch-users] PCMU codec issue (mismatch?) resulting in Incompatible Destination

I think that the 20 and 30 refer to 20ms or 30ms packetizing.  The 32000
and 64000 are the sampling rates.  You probably need to install all of the
sounds with:

make cd-sounds-install cd-moh-install

This will install the music and prompts in all the different sampling rates.
