We have G430 with S8300D LSP registered to remote CM. There are MM714 and MM710 boards inside. Outgoing faxes are working with no problem. However incoming faxes are not working. There can be heard short beep signal without fax tones. Trace shows the station going active and no more else. Is it providers problem? They are using Patton gateway. I gues it could be misconfigured.
