Hi Jerry, CMIIW, tail len setting on ES isn't as sensitive as EC, so your tail length settings above should be fine. However, as you've experienced that pjmedia ES doesn't help, so, as Benny mentioned before, I'm afraid that perhaps it's best to consider using VAS or APS. Btw, it is good to know that Audio Routing API doesn't turn on the hardware/built-in EC, while the built-in EC doesn't seem to be controllable by 3rd party app [1]. --- [1] http://wiki.forum.nokia.com/index.php/KIS000670_-_Echo_cancellation_cannot_be_controlled --- BR, nanang On Wed, Dec 9, 2009 at 3:18 PM, Jerry Monteiro <jerrym at matrixconsultants.com.au> wrote: > Hi Nanang > > I'm using the MDA version for a symbian app, and have not really changed any > 'out of the box settings'.
