Software s Armstrong MaX UC Desktop Software User Guide


You can use your Armstrong Unified Voice (AUV) phone service to make or receive calls from your desk phone, PC or Mac, and mobile devices.
For your phone service to work on your desktop, you need to install the MaX UC Desktop software. This guide helps you to do that.


MaX UC Desktop is supported on Windows 10 or 11 and Mac computers running macOS 10.15 (Catalina) or later.
You can use your computer’s built-in microphone and speakers, but you will have much better audio quality if you use a headset. MaX UC Desktop works with most common headsets, including Bluetooth variants. It even works with the answer/reject call button on some headsets.


Download MaX UC Desktop from: Open the downloaded file and follow the on-screen instructions to install the software.


Open MaX UC Desktop and select your service provider.

MaX UC Desktop is like having a desk phone on your computer. You can make and receive calls, put calls on hold, transfer calls, and make three-way calls.
You can also send instant messages, transfer files, and send presence information to other people in your corporate directory who are using MaX UC Desktop (on any device).
MaX UC Desktop uses the Wi-Fi, broadband, or mobile data services available and connected to your computer.

When someone calls your AUV number, you can see a pop-up window on your computer screen and hear a ringing tone through your speakers or headset. The pop-up shows the number of the person calling you. If the person’s details are in your contacts list, the pop-up displays the caller’s name.

Depending on the other services you have from Armstrong, you may see the incoming call on your desk phone, mobile phone, or tablet device. You can answer the call on whichever device is most convenient for you.

If the caller is in your Contacts list, you can reject a call and send the caller an instant message explaining why you can’t take the call. Select the drop-down list next to Reject and select one of the system messages, or select Custom Message to type your own message.

You may receive a call while you are already on another call. If you answer the new call, the current call is automatically placed on hold and the new call appears in a new call progress window. Switch between the two calls using the window for each one or select the Merge calls icon to merge other callers into a single call.

Software s Armstrong MaX UC Desktop Software User Guide - CALL MANAGER

You can choose Available for Calls or Do Not Disturb.

If you select Do Not Disturb, callers hear a recorded voice announcement saying that you are unavailable and are then connected to your voicemail. None of your devices will ring until you turn off Do Not Disturb, so be sure to use it carefully! When your phone is busy, you can set it to Forward to another phone (and enter the phone number to forward calls to) or Send to voicemail. You can also specify how calls should be handled if they are from anonymous numbers, from VIPs, or from numbers on your Unwanted Callers list. Note that when you change your Presence or Call Manager settings, the change applies on all of your MaX UC Clients. So, if you step away from your computer and forget to update your status, you could change your status using MaX UC Mobile on your mobile phone instead.

– Ctl-Alt-Shift-M to mute or unmute your microphone.


MaX UC Desktop lets you make calls from anywhere on the most convenient device. If MaX UC Desktop cannot automatically determine your location, the app notifies you to update your location information registered with your carrier in case you need to make an emergency call.


Once you have finished using MaX UC Desktop, select your avatar and select Quit to close the application. If you are using a shared computer, select your avatar and select Log Out to prevent other users from accessing your account. To change your log-in preferences, select your avatar, select Settings and, on the General tab, untick Automatically log in to MaX UC Desktop; this prevents MaX UC Desktop from logging in automatically when started and ensures that the next user has to log in using their own credentials.
