This article applies to NET SatisFAXtion version 8.6.


Inbound calls to lines connected to the FXO ports on an AudioCodes MP gateway return a remote busy or no answer. The NetSat IP ports do not answer the inbound call.


The NetSat IP ports do not close the FXO ports after the call completes. The ports remain in an off-hook state as indicated by the RTP active graphic in the MP interface.


The immediate solution to this problem is to download the updater program from the following link and then run it on the system to update the NetSat v.8.6 IP Fax driver.

Longer term - upgrade the NetSat 8.6 installation to version 8.7. Updater.exe
