I currently have 2 US Robotics modems installed on an SBS 2003 standard server. One modem is internal and the 2nd is external (model 5633b). These are used for incoming faxes.
I have tried to add a 3rd & 4th external US robotics 5633b modem, but SBS is not adding the new modems in Device manager. It replaces the existing external modem with the new modem.
Is there any limitations with SBS
