I just upgraded my Zaptel and Asterisk as mentioned in topic. Occasionally when I’m on a call, when I start talking, there will be a scratchy sound that seems to happen in sync with my voice. This did not happen before when I was using Asterisk 1.2.25 and a 1.2 version of Zaptel.
I’m using ECHO_CAN_MG2 and AGGRESSIVE_SUPPRESOR in zconfig.h, but that doesn’t seen to help.
I have a PRI coming in to a TE120P card, running FC7 with kernel 188.8.131.52-76.fc7.
