This warning means that asterisk received a "Comfort Noise" packet, which is G.729B specific.  Asterisk only negotiates support for G.729A but some other devices will still send these packets, so codec_zap will drop these packets when they arrive.

If you have purchased one of Digium's hardware transcoders, contact Digium technical support and they should be able to set up your environment to handle this condition.

Cheers,
Shaun
