[Asterisk-Users] Music on hold on timing sources

[C F]

When there is no timing source then MOH will not work, however
asterisk can use the incoming RTP stream as the timing source, if the
device you are trying to use don't send packets when there is no
sound, then there is no RTP stream, therefore no timing source.

Thanks.
