The default behavior is for there +# to be no default echo cancellers. +# +# Valid echo cancellers are: jpah, kb1, mg2, sec2, and sec. +# If compiled, 'hpec' is also a valid echo canceller. +# +# To configure the default echo cancellers, use the format: +# echocanceller=<echocanceller name>,<channel(s)> +# +# Example: +# Configure channels 1 through 8 to use the mg2 echocanceller +# echocanceller=mg2,1-8 +# +# And change channel 2 to use the kb1 echocanceller. +# echocanceller=kb1,2 +# |
