Speex dev - Feb 2006 - Problems with MDF

Hi, I'm still trying to implement speex AEC into my VOIP project and I have
some problrm with MDF filter response. I have plots of ref(near-end), y(filter
response) signals and from plots I obtain that filter response is to small so
when i substruct it from ref signal there is no efect. Is there any way to make
filter giving response about ref signal amplitude?

understand about echo cancellation:

More specifically, the following part describes common problems that can
cause echo cancellation not to work:

Hi there,

Does someone ever try to get Speex 16000 working with Asterisk ?
