[asterisk-users] disable comfort noise

[adamk at 3a.hu]

To get back to the original poster's possible situation, i've seen this 
with my first IP phone, which was a cisco 7912 (SIP image).  With that 
phone, asterisk sometimes gave me this same error.  I'm quite sure i've 
asked the very same question here back then (probably i was a bit more 
specific :).  Since it is related to only this type of phone, i've gone 
to different ip phone products.
