Yes. Here is a website that we recommend for speed tests – http://zultys.speedtestcustom.com. We’ve found that it provides good results for potential customers testing their networks. There are several other test sites that you can find online and are free to use, but we know this one has performed consistently well for our customers.

Zultys phones have up to 3 different methods to connect headsets depending on the model.

1. RJ9 (33i, ZIP 35i, ZIP 33G, ZIP 36G, ZIP 37G, ZIP 43G, ZIP 45G, ZIP 47G, and ZIP 49G)
2. USB (ZIP 45G, ZIP 47G and ZIP 49G)
3. Bluetooth (ZIP 45G, ZIP 47G and ZIP 49G)

RJ9 headset compatibility is the same for all these models so if the Plantronics or Jabra web site says the headset is compatible with a ZIP 35i it will work with a ZIP 43G.

The Plantronics (https://www.plantronics.com/us/en/support/compatibility-guide) or Jabra (https://www.jabra.com/compatibilityguide/) web sites may not list all of the ZIP3/ZIP4 models but if they list any of them the others will work as well.

ZIP 4 Series Detailed headset compatibility guide Plantronics, Jabra, Sennheiser
Z 2 Series Detailed headset compatibility guide Plantronics, Jabra, Sennheiser

• Plantronics: CS60, CS70, CS500 series, Savi W700 series, Voyager Pro w/adapter, Voyager Legend w/adapter.
• Jabra: PRO 9400 Series, GO 6470, PRO 920, GN9350e, GN9330e, GN9120 EHS

EHS (Electronic Hook Switch) compatibility enables call control (answer and hang up) from buttons on the headset.

• ZIP 35i, ZIP 36G, ZIP 37G, ZIP 43G, ZIP 47GE phones using RJ9 jacks support EHS with the optional Zultys EHS 3xi Adapter.
• ZIP 45G, ZIP 47GE, ZIP 49GE phones using RJ9 jacks support EHS with the optional Zultys EHS 4x Adapter.
• ZIP 45G, ZIP 47GE. also supports Bluetooth headsets with EHS with the optional Bluetooth adapter and USB headsets (see compatibility guide).
• ZIP 49GE phone supports EHS using built in support for Bluetooth headsets and USB headsets (see compatibility guide).
  • Plantronics headsets such as CS500 series that don’t include USB connectivity can use the Plantronics APU-75 EHS cable to connect to the USB port instead.
• ZIP 59i. Check Plantronics and Jabra web sites for compatible headsets. Built-in support for Bluetooth headsets.
• Note the ZIP 33i and ZIP 33G phones don’t support EHS.

Softphones

ZAC softphone no EHS: Call control takes place from ZAC

• Softphone headset compatibility is based on compatibility with your PC or Mac. ZAC softphone utilizes the native PC or Mac audio drivers. You can connect virtually any headset to the computer and be able to answer calls directly from the ZAC application.
• 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.
• Bluetooth headsets will work but audio quality depends on the capabilities of the headset and Bluetooth radios in the computer. 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. Most Windows computers don’t include the high quality Bluetooth radios but most Macintosh computers do.
• If callers report they hear an echo when talking to you, go to the computer Control Panels/System Preferences and reduce the sound input or output level until the echo goes away. This is usually a very small adjustment.

ZAC softphone with EHS: Most Plantronics USB and Bluetooth headsets use the modern HUB architecture and are automatically supported when using ZAC on your PC or Mac. No driver software needed.

1. Connect Plantronics headset
2. Open ZAC and Bind to Internal Softphone
3. Go to ellipsis (…)/Settings
4. Click on the Softphone icon and select Plantronics device

An action is needed such as picking up the handset, pressing the Speaker button on the phone, or pressing the SEND key (like on a cell phone).

By default, ZIP3 phones are configured to use distinctive ringing so users may differentiate between an internal and an external call. A side effect of that is that the Common Ring Tone option available from the Telephone UI will not have any impact on the ring tone played when a call is received.

This setting can be changed by your system administrator. This is usually set the same way for all phones for a consistent experience.

Zultys is generally agnostic regarding brands and models of switches and routers.

• We do recommend switches that provide Power over Ethernet (PoE) as it simplifies cabling and makes it easy to deploy a UPS (Uninterruptible Power Supply). All of our phones support the 802.3af standard for PoE. PoE+ also works but is not required.We can suggest what to avoid.

• Avoid consumer-class / home-class routers with built-in WiFi unless it is for very small installations, as these often don’t have full control of all functions like disabling SIP inspection / ALG / SIP Fixup, etc. Enterprise-class network equipment will provide the ability to control these and other features such as VLAN, QoS, LLDP, etc.Firewalls/Routers. Note:Zultys generally does not guarantee or support network equipment. These are suggestions and settings that our users have found helpful.
• Edgewater Networks. https://edgewaternetworks.com/Firewalls/Routers – Known issues with suggested fixes.
• Cable Modem Internet Service Providers
  • Comcast: It is difficult to get Comcast to turn off ALG. The best solution is to get a local router that allows you to turn off ALG. Have Comcast set their cable modem to “Bridge Mode” or “Pass through Mode,” which will turn off ALG. Your local router will provide protection to your network. See the notes below for disabling ALG.
  • Alternatively, many providers will let you buy your own cable modem and firewall/router which allows you to control all the settings, including ALG.
  • AT&T UVerse: They can turn off ALG, but it will take persistence to the right person at AT&T UVerse support to do it. Alternatively, they are able to set their device to “Bridge Mode.” Your local router will provide protection to your network. See the  notes below for disabling ALG.

• Fortinet/FortiGate: SIP ALG is turned on by default, which causes problems.

In Fortinet’s GUI under the dashboard there is a CLI prompt. Enter these commands:

• config system settings
• set sip-helper disable
• set sip-nat-trace disable
• set default-voip-alg-mode kernel-helper-based (If you see error here – ignore it)
• end (Brings you back to main login)
• config system session-helper
• show (You need to find the entry for SIP, usually 13, but can vary)
• delete 13 (Or the number that you identified from the previous command)
• end (Brings you back to main login)
• config voip profile
• edit default
• config sip
• set rtp disable
• end
• end (Brings you back to main login)
• Reboot firewall
• Set Inspection Mode to “Flow-Based” it is “Proxy” by default.
  
• 

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