6.1. Zultys ZAC — End-User Login & Setup

Last updated: Thu Oct 2025 03:26 PM (EDT)

Summary: Use Zultys Advanced Communicator (ZAC) to place/receive work calls from your CRL PC (softphone) and keep your personal number private.

What is ZAC?

Zultys Advanced Communicator (ZAC) lets you use your CRL work number on your computer (and optionally mobile).

• Single Number Reach (SNR): One work number across devices.
• Consistent Caller ID: Calls show your CRL identity regardless of device.
• Voicemail to Email: Voicemails are delivered to your CRL mailbox.

Before you start

You'll need the following: 

• A CRL-issued Windows PC with ZAC installed or a smartphone with the ZAC app installed*
• Your CRL username (the part before @ in your email, all lowercase).
• Your ZAC/voice password (provided by IT).
• A working headset or speakers/microphone.

Sign in on your CRL PC (Softphone)

1. Open ZAC from the Windows Start menu. If not installed, open a HelpSpot ticket.
2. At the login screen, enter:
   • Login: your CRL username (lowercase)
   • Password: your ZAC/voice password (provided by IT)
   • Host: mxe.crltechnologies.com
   • Use Windows Credentials: leave off
   • Remember password: optional on trusted CRL devices only
3. Click Login.

First-time prompts: Role & Location

On first sign-in you may be prompted to choose:

• Role Selection: If you don’t see this, no role is assigned (default). If you do, follow guidance from your manager.
• Location: Choose your CRL office or the site you are working from. If none apply, select Unknown.
• Apply to future login: Toggle on to save your choices. Leave off if you regularly switch sites.

You can change these later in Settings.

First-time voicemail setup (recorded name)

You only need to record your name. Keep the default greeting.

1. In ZAC, open Voicemail from the left panel.
2. Click Greetings.
3. Under Recorded Name, click the microphone icon.
4. Say your name clearly, then click Stop.
5. Click OK to save.

• The Voicemail Settings dialog box will open

• Under the Recorded Name window

• Click the microphone icon to start the recording

• 

• Say your name loudly and clearly

• 

• Click the Stop icon

• Your Name has been saved

• 

• Click OK to close the window and save your settings.

Bind to Softphone (use your PC for calls)

1. In the lower-left of the ZAC window, click Bind to….
2. Choose Bind softphone. The footer should show Softphone once bound.

Post-setup checks (recommended)

• Outbound test: Call IT at ext. 2204 or a teammate. Confirm your mic/speakers work.
• Inbound test: Have someone call your extension. Verify ZAC rings and you can answer.
• Voicemail test: Leave yourself a voicemail. Confirm it arrives in your CRL email within a few minutes.

Troubleshooting

Can’t sign in

• Confirm your username is all lowercase.
• Verify Host is mxe.crltechnologies.com.
• Re-enter the ZAC/voice password (check for typos).
• Still stuck? Open a HelpSpot ticket with IT.

No audio / can’t hear caller

• Check Windows sound settings and that your headset is the default.
• Ensure ZAC is Bound to Softphone (see footer).
• Try unplugging/replugging the headset or selecting the device in ZAC audio settings.

Voicemail not in email

• Wait a few minutes and check Junk Email.
• If still missing, open a HelpSpot ticket with IT.

Support

If you need ZAC installed, password assistance, or run into errors, open a HelpSpot ticket and include:

• Your full name and CRL username
• Device name/asset tag (if known)
• A brief description of the issue and any error text
• Whether you’re on-site or remote and a callback number
