Placing a Call ౼ Direct Dialing
To directly dial a number with your Mitel 5320e IP phone, simply lift the handset or press the speakerphone button to activate the line. Then, use the keypad to enter the complete phone number, including any necessary area codes. The phone will automatically initiate the call after you’ve entered the final digit.
Ensure the number is dialed correctly before pressing the send key (often indicated by a phone icon). The display screen will show the call progress, indicating when the connection is being established. If the number is invalid or unreachable, an appropriate error message will appear on the screen, prompting you to verify the dialed number.
Answering an Incoming Call
When receiving a call on your Mitel 5320e IP phone, both the display screen and a visual indicator (usually a flashing light) will alert you. To answer the call, simply lift the handset from the cradle or press the speakerphone button. The call will connect immediately, and you can begin your conversation.
The caller’s information, if available (such as name or number), will be displayed on the phone’s screen. You can also use a dedicated answer softkey, if configured by your system administrator, to accept the incoming call. Ensure a clear connection before commencing your discussion.
Call Hold and Retrieve

Follow the voice prompts to navigate the voicemail menu. Common options include listening to new messages, checking message count, and accessing saved messages. Ensure your phone is connected to the network for seamless voicemail access. Contact your administrator if you encounter any issues with voicemail access or password resets.
Voicemail Message Playback
Once you’ve accessed your voicemail, use the navigation keys on your Mitel 5320e to manage message playback. Typically, the ‘Play’ or ‘Forward’ key advances to the next message, while the ‘Rewind’ or ‘Back’ key returns to the previous one. Volume control adjusts the playback level.

Phone Settings and Customization
Personalize your experience! Adjust volume, ringtones, date/time, and basic network settings directly on your Mitel 5320e for optimal usability.
Adjusting Volume Levels
Control your audio! The Mitel 5320e allows precise volume adjustments for handset, headset, and speakerphone modes. Utilize the dedicated volume control keys – typically located on the front or side of the phone – to increase or decrease the audio level to your preference.
During a call, these keys dynamically adjust the output volume. When not on a call, they control the ring volume. Some models feature a mute function, instantly silencing the speakerphone. Experiment to find comfortable levels for various environments and ensure clear communication. Remember to check your system administrator’s settings as well.
Changing the Ringtone
Personalize your alerts! The Mitel 5320e allows customization of your incoming call ringtone. Access the phone’s settings menu – typically through a ‘Settings’ or ‘Options’ softkey – and navigate to the ‘Ringtone’ or ‘Audio’ section.
A list of available ringtones will appear; preview each option to select your preferred sound. Some systems allow uploading custom ringtones, though this may require administrator privileges. Changing the ringtone helps differentiate calls and personalize your workspace. Ensure the selected tone is audible and appropriate for your office environment.
Date and Time Settings
Accurate timekeeping is crucial! The Mitel 5320e’s date and time settings ensure correct call timestamps and synchronization with the network. Access these settings via the phone’s menu, usually under ‘Settings’ or ‘Preferences’. You may find options for ‘Date Format’ and ‘Time Format’ (12/24 hour).
Typically, the phone automatically synchronizes with the system’s time server. However, manual adjustment is possible if needed. Incorrect date/time settings can affect call logs and scheduling features. Verify these settings periodically to maintain accurate phone operation and consistent system-wide timekeeping.
Network Configuration (Basic)
Initial network setup is often automatic! The Mitel 5320e typically receives network settings via DHCP from your system administrator. However, basic configuration options might be accessible through the phone’s menu, usually under ‘Network’ or ‘Settings’. These options may include viewing the assigned IP address, subnet mask, and gateway.
Manual configuration is generally not recommended unless specifically instructed by your IT department. Incorrect settings can prevent the phone from registering to the network. Contact your administrator for assistance with any network-related issues or if static IP addressing is required.

Troubleshooting Common Issues
Facing problems? This section provides solutions for typical Mitel 5320e issues, including no dial tone, poor audio, and network registration failures—resolve them quickly!
No Dial Tone Troubleshooting
Experiencing no dial tone? First, verify the handset is firmly seated in the base. Ensure the network cable is securely connected to both the phone and the wall jack, or network switch. Confirm the power adapter is properly plugged into a working outlet and the phone.
Restarting the phone can often resolve temporary glitches. If the issue persists, check if other phones on the network are functioning correctly to isolate the problem. Contact your system administrator to verify your phone is provisioned correctly within the Mitel system and that there are no account restrictions;
Poor Audio Quality Solutions
Experiencing muffled or distorted audio? Begin by checking your headset or handset for damage. Ensure the volume level is appropriately adjusted – too high or too low can cause distortion. Verify the network connection is stable; a weak signal impacts audio quality.
Try restarting your phone and, if using a headset, test with the handset to isolate the issue. Contact your network administrator to investigate potential network congestion or Quality of Service (QoS) settings. A firmware update might also improve audio performance.
Phone Not Registering to the Network
If your Mitel 5320e fails to register, first confirm the Ethernet cable is securely connected to both the phone and the network port. Verify the network port has power and is active. Check the phone’s network configuration settings – ensure the correct IP address, subnet mask, and gateway are entered.
Restarting the phone and your network equipment (router/switch) is a good first step. Contact your IT administrator to confirm the phone is provisioned correctly on the Mitel system.
