[Freeswitch-users] Acoustic Echo Cancellation on Freeswitch side

Hi there, I was wondering whether there were any echo cancellation alternatives available that could potentially work on the Freeswitch server side. 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. Thanks! Imran
