Call Performance

There are many components to bring quality VoIP communication to the customer. The phone/headset itself, being the customer’s point of reference, usually takes the blame for anything that is not functioning properly.

Communication is two way and sound quality issues can result from the incoming caller’s own issues with connection, mobile signal, device or service. If the reported problem occurs only a few times or only with the one incoming caller, it is possible that the incoming caller has service disruption. Monitoring, recording instances of the problem (time, date, caller), and following up with a service call if the problem persists, is recommended.

Reboot Desktop Phone

Rebooting the phone can be done in one of two ways, this may be needed when system adjustments have been made or the phone is not functioning as expected. Rebooting the phone will take a minute or two and cannot be done while the phone is in use.

  1. Reboot from the device menu screen.
    1. For T54/T46 devices: Using the soft keys select Menu, use the up/down arrows to move to Basic and press OK, use the down arrow to scroll to Reboot and select, then select OK.
    2. For T53 devices: Using the soft keys select Menu, use the down arrow to move to Settings, select first option Basic Settings and press OK, use the down arrow to scroll to Reboot and select, then select OK.
  2. Unplug the power cord, wait 20 seconds, and plug the power cord back into the phone.

ISP/Network Concerns

If the device is experiencing regular one way communication, jitter, static, or dropped calls it is likely the result of ISP connectivity or network routing/equipment configuration. Determine if any ISP/network changes, equipment changes, interruptions or updates have recently been made. Confirm that routing equipment QoS for VoIP is enabled, and if any dedicated VLans for VoIP are present they are configured correctly to allow packet transfer in and out for VoIP without redirection or delay.

“No Service” appears on the device home screen, when it is unable to successfully connect to the network. If the phone was previously working, and this error is quite sudden or appears after a power outage, unplug the device from all cables, wait for 30 seconds and plug the device back in. This should reboot the device on a working network so it can regain connection. This can result on devices that are using a power supply or POE.

WiFi

Devices connected to the internet over WiFi need to maintain signal strength and consistency adequate to support voice data. If WiFi is not able to support voice data the device will need to be hard wired to the internet.

Do Not Disturb (DND)

When enabled device will not ring and calls will go to voicemail. Red shield icon like a Do Not Enter sign present on the top of the phone screen. Also present will be a notification box on the screen saying “DND mode is enabled”. Disable DND by selecting the Soft Key labeled DND or Select Menu>Features>Scroll down to DND and select>turn DND off>OK.
