[asterisk-users] Multicast Paging

[Jonathan C. Bailey]

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}"
