+ECHO cancellation function


+ECHO AT command include many parameters and several algorithms.
I dont understand their meaning and i simply want to have
set of profiles for concrete application such as (for example):

  • Ear Seal Echo Cancellation
  • Head Set Echo Cancellation
  • AEC
  • Speaker Echo Cancellation for car kit operation
    and so on…

can anybody decribe me interaction of +ECHO parameters
with “standard” real profiles. I mean, what programm to +ECHO
if i want car kit profile, handset, headset and so on…
