I have a new M8L that I am having real problems with. I managed to get it setup and configured with 4 FXO lines. It would properly route incoming calls to 00 and process routing to the appropriate extension. Extensions however could not place outgoing calls - "waiting to connect". I downloaded and installed the latest firmware 5.3.23 and now I can't open the web interface. Tried to reset to factory but that doesn't appear to be working. Any ideas?
