I have connected LS trunks to GSM passarelle (Ericsson G36).
I'm experiencing bad quality audio when calling thru mitel phones.
I think it could be impedance difference between MITEL and GSM interface.
Do you know parameters to change on ICP ?

ICP 3300 Mxe 9.0 UR2


Now, it's about French users too !!!
 
Follow the procedure for using and applying the line measurement tool.

Yeah I know; I've forgotten to tell that result indicates : "UNKNOWN" RED, for recommended settings !!!

Now, it's about French users too !!!
 
I have also found that "a SHARC Enhanced DSP card with an ADSP 21161N processor is requested to perform tests.
I have a SHARC 21262 DSP

Now, it's about French users too !!!
 
Did the test complete successfully? I mean was it 'test complete, with a RED inidication', or was it 'test failed'? If the test completed, then it is in fact an impedance mismatch.

Also, the bit about the 21161 dsp. By that I believe they mean that you need 'at least' that, specifically older systems with 21061's won't support the tool.
