[Freeswitch-users] change the remote RTP port after sample rate doesnot match

[Erwin Davis]

Hi, Anthony,

Thanks for your reply.

When I type the command below, I got the error,
Unknown target hd-sound-install
make[1]: *** [hd-sound-install] Error 1
make: *** [hd-sound-install] Error 2

I found out that under /usr/local/freeswitch/sounds/en/us/callie/voicemail,
there are directories, 8000, 16000, 32000, 48000 for recorded voicemail
greetings. It should explain why at first FS played in right sample rate.
But after playing serveral time, FS complained about sample rate not
matching.  Any clue? Thanks,
