I know this may be a bit off topic...
I'm trying to play a pre-recorded message to a group of Aastra phones using
multicast paging. I can page phone to phone without issue, but sending from one
of my servers to the phones results in garbled audio. Anyone else been able to
make this work without problem? My VLC command line is below.
cvlc -v emergency-test2.wav --norm-max-level=5 --sout
"#transcode{acodec=ulaw,ab=64,channels=1,samplerate=8000}:rtp{dst=239.0.1.20,port-audio=16000,proto=udp}"

And MAST is a good alternative to try. Cheers, Philipp
