Well, when we made them modular so that people could pick and choose at run-time instead of compile-time, it seemed like forcing a default on everyone was the wrong thing to do... especially for people who don't need them at all because they have hardware echocancelers. In hindsight, this has probably been the biggest issue with people upgrading from Zaptel to DAHDI, and we should have just had some sort of default. We've had some discussions about making dahdi_cfg supply a default echo canceler for all channels that don't have one specified, but then that of course will require the ability to tell it "no, I don't want one". -- Kevin P.
