Hi Guys, I am having a similar issue with no audio. Other end is an ericsson switch. See the logs below. I can make and receive calls fine but no audio. I checked my CIC and they are lined up well. I run dahdi_monitor but I only see activity from my end (softphone registered on asterisk). Nothing from the far end. One strange thing I notice is the # sign at the end of the numbers in the logs.
