The default codec list of the OBi1110 includes the codec G711U. However in some country, G711U does not give satisfactory perforamnce, as a result, we have to use other codecs such as G711A and G729. When we try echo test using either G711A or G729 codecs, the echo test DOES NOT work.
My questions is does anyone experience the same situation as I do?
