[asterisk-users] Audiocodes MP-114 noise

[Jessee J Holmes]

Jason,

There are a couple things we can try to fix your problem.

Your firmware shouldn't be an issue, but latest I've got now is:  
MP118_SIP_F4.80A.034.004.cmp

Let's try some quick things first though:

In your web interface, go to advanced config - channel settings /  
voice settings

There are some options here you can play with:

"Voice Volume" (IP side of this thing) - by default this should be  
set at '1'. Try bringing this down slowly, I'd say in increments of 5  
(-4, then -9, and so on).

Range on this option can be anywhere from -32 to +32, you really  
shouldn't need to go beyond -15; but you're actual volume on the  
calls should still stay reasonable.

"Input Gain" (telco side) is another option you can slowly change as  
well (set to 0 by default).

There should also be spot where you can specify the "codername", you  
could possibly try changing this to another codec such as G.729 or G. 
711u-law (should be the same codec being used on your Asterisk  
system) try changing packet size from 20 to 40 or 60. This may also  
help.

If none of this stuff helps, let me know. We can then start getting  
really technical.
