Oslec is a line echo canceller and its license is incompatible with FreeSWITCH. Acoustic echo cancellation needs to be done by the handset. Speex preprocessor has an echo canceller, but I don't know how good it is. On Mar 29, 2012, at 10:37, Bzzz <lazyvirus@gmx.com> wrote:

I was wondering whether there were any echo cancellation alternatives available that could potentially work on the Freeswitch server side.
May be you should search for: voip echo oslec
This is mainly to cater for people that dial into my service using just their laptop microphone + speakers and their client app doesn't support echo cancellation.
I realize that this could be an expensive proposition (from a computational perspective) but curious if the option (commercial or otherwise) exists.
A (good) commercial proposition should be to ask these people to buy a correct headset...
