Basic Phone Operation
Mitel phones facilitate seamless communication with standard functions: making and answering calls, utilizing hold features, and efficiently transferring connections to colleagues.
Making a Call
Initiating a call on your Mitel telephone is generally straightforward. First, lift the handset or ensure the headset is connected. You can then dial the desired phone number directly using the keypad. Alternatively, you might select a contact from the phone’s directory, if one is configured.
Many Mitel models offer speed dial functionality, allowing quick access to frequently called numbers. Before dialing, verify the area code is correct, especially for long-distance calls. The phone will typically provide audible feedback, such as a dial tone, to confirm the number is being processed. Once connected, clear audio indicates a successful call establishment. Remember to consult your specific model’s guide for unique dialing procedures.
Answering a Call
Responding to an incoming call on a Mitel phone is typically done by lifting the handset. Many models also allow you to answer by pressing a dedicated answer/accept key, often indicated by a green button. Visual cues, such as a flashing indicator light, signal an incoming call.
If you’re using a headset, answering may involve pressing a button on the headset itself. Some Mitel systems support automatic answer features, though these are usually configurable. Upon answering, ensure clear audio and confirm the caller’s identity if necessary. The phone will typically display caller ID information, if available, aiding in call management.
Putting a Call on Hold
Placing a call on hold with a Mitel phone is straightforward. Typically, a dedicated “Hold” button, often visually represented by a pause symbol, initiates the hold function. Pressing this button suspends the call while maintaining the connection. The caller will usually hear hold music or a pre-recorded announcement.
To retrieve a call from hold, simply press the same “Hold” button again, or the corresponding flashing line key. Ensure you promptly return to the call to maintain a positive customer experience. Some Mitel systems offer features like warm transfer from hold, allowing seamless handoffs.

Advanced Features
Mitel systems excel with features like call transferring, robust conference calling, and comprehensive voicemail access – enhancing communication capabilities significantly.
Call Transferring
Call transferring on a Mitel system allows you to seamlessly redirect an active call to another extension or even an external number. This is incredibly useful when you need assistance with a call or when the intended recipient is unavailable. Typically, you’ll initiate a transfer by pressing a dedicated ‘Transfer’ soft key, then dialing the extension or number of the person you wish to connect the caller with;
Some Mitel phones offer options for ‘blind transfer’ – immediately transferring the call without confirming the recipient is available – or ‘warm transfer’ where you briefly speak with the recipient before connecting the caller. Understanding these options ensures efficient call handling and excellent customer service within your organization’s communication framework.

Conference Calling
Mitel telephone systems facilitate efficient conference calling, enabling multiple parties to participate in a single conversation. To initiate a conference, you generally place the first caller on hold, then dial the number of the next participant. Once connected, you’ll typically use a ‘Conference’ or ‘Join’ soft key to bring all parties into the call.
The system often supports adding multiple participants, up to a predefined limit. Features like muting individual lines and controlling volume levels are commonly available during a conference. This functionality streamlines collaboration, reduces travel costs, and enhances communication for teams and clients alike, making Mitel a powerful business tool.
Voicemail Access and Management
Mitel voicemail systems offer secure message storage and retrieval; Access is typically gained via a dedicated voicemail key on your phone, prompting for a password. Once logged in, you can listen to new and saved messages, delete unwanted voicemails, and manage greetings.
Many Mitel systems provide visual voicemail, displaying a list of messages with caller ID information. Options for forwarding voicemails to email are also frequently available. Regularly checking and managing your voicemail ensures you don’t miss important communications, contributing to efficient workflow and client responsiveness within the Mitel environment.

Navigating the User Interface
Mitel phones feature intuitive displays and soft keys for quick access to functions like call control, voicemail, and settings adjustments.
Understanding the Phone’s Display
Mitel telephone displays are designed for clarity and ease of use, presenting crucial call information at a glance. Typically, you’ll find sections dedicated to the current call status – including duration and caller ID – alongside soft key functions. These soft keys dynamically change based on the active task, offering context-sensitive options like ‘Transfer,’ ‘Conference,’ or ‘Hold.’
The display also often includes icons indicating voicemail messages, line status (available, busy, ringing), and feature activation. Navigating menus is usually achieved through directional keys and a central ‘Select’ or ‘OK’ button. Understanding these visual cues and interactive elements is fundamental to efficiently operating your Mitel phone system and maximizing its capabilities;
Using the Soft Keys
Mitel phone soft keys are dynamically assigned buttons located directly beneath the display, offering quick access to frequently used functions. Their labels change depending on the current call state or menu selection. For example, during an active call, soft keys might display options like ‘Transfer,’ ‘Conference,’ or ‘Hold.’
To utilize a soft key, simply press the corresponding button. These keys streamline common tasks, eliminating the need to navigate complex menus. Familiarizing yourself with the typical functions assigned to soft keys – and observing how they adapt to different scenarios – will significantly enhance your efficiency when using your Mitel telephone system.

Troubleshooting Common Issues
Mitel systems can experience issues like no dial tone or poor audio, potentially linked to MiCollab/MiVoice systems and VoIP interface cards.
No Dial Tone
Encountering no dial tone on your Mitel telephone can be frustrating, but several troubleshooting steps can resolve the issue. First, verify the physical connection – ensure the telephone cord is securely plugged into both the phone and the wall jack or network port. Confirm the power adapter is correctly connected and functioning.
Next, check for any service outages reported by your telecommunications provider. If no outage exists, attempt to use a different phone on the same line to isolate the problem. If another phone works, the issue likely lies with the original handset. Finally, consult your system administrator to verify your extension is properly provisioned within the Mitel system.
Poor Audio Quality
Experiencing poor audio quality during calls on your Mitel phone can stem from various factors. Begin by checking your headset connection – ensure it’s firmly plugged in. Test with a different headset to rule out a faulty device. Verify the volume level on your phone is appropriately adjusted.
Network congestion can also contribute to poor audio; try making calls during off-peak hours. If using VoIP, assess your internet connection speed and stability. Finally, contact your system administrator to investigate potential issues with the Mitel system’s configuration or Quality of Service (QoS) settings.
Problems with Headsets
Encountering issues with your headset on a Mitel phone? First, confirm the headset is fully compatible with your specific Mitel model. Ensure the connection is secure – try disconnecting and reconnecting the headset cable. Test the headset with another phone to isolate the problem.
If the headset has volume controls, verify they are appropriately adjusted. Check the mute function isn’t accidentally activated. For wireless headsets, ensure they are charged and properly paired with the phone’s base station. If problems persist, consult your system administrator for assistance.
