How do I install the FAX print drivers for Windows and Macintosh?

Windows: Download and install the appropriate print driver from the web page of your MX.

Troubleshooting Installer was interrupted before Zultys Fax Printer could be installed (Windows 7, 8.0/8.1 and 10)

In some cases you may see this notification, which is the result of Microsoft patch KB3072630 and only affects the installation of the driver.

Once the print driver is installed it will work correctly.

  • Launch “regedit”
  • Locate and click the following subkey in the registry:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer
    • Note: If this subkey does not exist, create it.
  • In the ‘Edit’ menu, point to ‘New’, and then click ‘DWORD Value’.
  • For the DWORD name, type “RemappedElevatedProxiesPolicy”, and then press ‘Enter’.
  • Right-click “RemappedElevatedProxiesPolicy”, and then click ‘Modify’.
  • In the ‘Value’ data box, type 1, and then click ‘OK’.
  • Install Zultys Fax Driver
  • After the application installs successfully, reset the RemappedElevatedProxiesPolicy’ DWORD value to “0” to re-enable the security fix for KB 3072630.

Which headsets are supported?

Phones ZIP 33i, 35i, 36G, 37G, 59i. The ZIP3 phones (33i, 35i, 36G, and 37G) support the same headsets (see note about EHS* below). The Plantronics or Jabra web sites may not list all of the ZIP3 models but if they list any of them the others will work as well.

  • Plantronics: CS60, CS70, CS500 series, Savi W700 series
  • GN Netcom/Jabra: PRO 9400 Series, GO 6470, PRO 920, GN9350e, GN9330e, GN9120 EHS

MXIE softphone: Call control takes place from MXIE

  • Softphone headset compatibility is based on compatibility with your PC or Macintosh. MXIE softphone utilizes the native PC or Macintosh audio drivers. You can plug in virtually any headset into the computer’s audio jack and be able to answer calls directly from computer via MXIE.
  • USB headsets generally provide better quality than analog headsets plugged into computer audio jacks. Some headsets support very high quality audio with terms like WB (wide band) or HD (high definition) and may include noise cancelling features.
  • If you would like to utilize Bluetooth headsets, Zultys recommends the following models for the highest audio quality. Plantronics Voyager Pro HD and Plantronics SAVI W440 are examples of high quality Bluetooth headsets. Plantronics also sells the BT300 adapter for computers that lack high quality Bluetooth radios. Many Windows based computers don’t include the high quality Bluetooth radios, which could cause less than ideal audio quality, but most Apple Macintosh computers come with high quality Bluetooth radios included.

MXIE softphone: Call control (EHS) from select Plantronics USB or Bluetooth headsets when using MXIE on your computer (Windows only).

  • Beginning with MX firmware release 9.0.4, MXIE for Windows supports call control from Plantronics headsets that support the Plantronics Spokes software. This integration requires the Plantronics software that can be found on your MX software download page where it is called Plantronics SKD Lite.
    Installation instructions (MXIE for Windows only)

    1. Download and install the Plantronics Spokes/SDK Lite software with MXIE NOT running
    2. Connect Plantronics headset
    3. Open MXIE and Bind to Internal Softphone
    4. Open MXIE Preferences/Softphone/Audio Parameters and select Plantronics device
*Which phone models support EHS (Electronic Hook Switch)?

Models ZIP37G, ZIP36G, ZIP35i, supported with an EHS 3xi Adapter (Part Number: 90-09301 – includes all required cables). Note ZIP33i and ZIP33G do not support EHS.

What network equipment is recommended for customer sites?

While Zultys is generally agnostic regarding brands and models of switches and routers, for best audio performance on your office phone system, Zultys recommends:

  • Switches that provide Power over Ethernet (PoE) simplify cabling and make it easy to deploy a UPS (Uninterruptible Power Supply). All of our phones support the 802.3af standard for PoE, which allows you to unclutter your desk from redundant Ethernet cables. PoE+ also works but is not required.

For best audio performance on your office phone system, Zultys recommends avoiding the following:

  • Avoiding consumer-class / home-class routers with built-in Wi-Fi. While such routers could be deployed for a one or two person shop, these types of routers don’t provide full control of functionality which would greatly improve your connection quality. For example, functions such as disabling SIP inspection / ALG / SIP Fixup, etc. allow for significant performance increase and will make your network connection much more reliable and stable, optimizing your business productivity. For optimum call quality, enterprise class network equipment will provide the ability to control these and other features such as VLAN, QoS, LLDP, etc. Firewalls/Routers.

The following are suggestions and settings that our users have found helpful.

Firewalls/Routers – If utilizing the following firewalls or routers, please take note of the suggested setting changes.

  • Edgewater Networks https://edgewaternetworks.com/
  • Fortinet/FortiGate – if utilized, for optimized performance, please turn off the SIP ALG feature, which is turned on by default.
    1. Open the Fortigate CLI from the dashboard.
    2. Enter the following commands in FortiGate’s CLI:
      1. config system settings
      2. set sip-helper disable
      3. set sip-nat-trace disable
      4. set default-voip-alg-mode kernel-helper-based
      5. end
      6. reboot the device
    3. Reopen CLI and enter the following commands – do not enter the text after //:
      1. config system session-helper
      2. show //locate the SIP entry, usually 12, but can vary.
      3. delete 12 //or the number that you identified from the previous command.
      4. end
    4. Disable RTP processing as follows:
      1. config voip profile
      2. edit default
      3. config sip
      4. set rtp disable
      5. end
      6. end

There might be other settings that you need to configure to improve quality even further depending on the FortiOS version that you are using. If you continue encountering issues related to SIP ALG, please contact Fortinet Support.
