Frame type '10' is a CNG (Comfort Noise Generation) frame. This is a
frame that, instead of carrying audio, carries a command to for the
receiver to generate "comfort noise" for a length of time to the
local user.
chan_dahdi is not currently capable of generating comfort noise in
response to receiving one of these frames.
I think it's safe to ignore them. Alternatively, if the comfort
noise packets are generated from SIP endpoints that you have control
over, you could see if there are any options to disable generation
of those frames.
Hello!
Thank you!
I accidentally deleted you messages, so I just copied it from mail list
archive,
this will break thread :-(
Today I found that we receive such frames during call to/from mobile phones,
so these messages are really harmless.
