I get a strange error when I start MOH via the Dial() m option.
This error prints to the console multiple times and is somewhat annoying, however it doesnt seem to have any affect on the call. I am disallowing ulaw in my sip.conf. Google didn’t really provide relevent results
This can happen when there is a reconfiguration in the internal transmission paths. It should be ignored unless the console is being flooded with these messages, in which case one would also expect one way audio.
