Konftel 800 can bridge all these connections together into a combined call.

When bridging your computer and the phone, you must activate both sources of sound. Konftel 800 can handle full duplex, echo cancellation, and noise reduction for all bridged sound sources simultaneously. The sound from the bridged computer and SIP call can have different levels. To hear all participants of the conference call clearly, adjust each sound source individually.

Konftel 800 does not support bridging of Bluetooth® calls with SIP and USB calls.

Features and Accessories

Expansion of the Phone Coverage

Use your Konftel 800 on larger conference tables or when the number of a meeting participants is greater than 10. In this case you can ensure high-level quality of audio signal by expanding the phone coverage in the room without a PA system. Do it by connecting Smart Mic expansion microphones to the phone or by cascading several Konftel 800 devices in a daisy chain.

Expansion of the phone coverage helps to improve the audio quality in large rooms. The conference phone and two Smart Mics increase the capture range from 30 square meters to up to 70 square meters. Three phones in a daisy chain increase the range from 30 square meters to up to 90 square meters.

Expansion coverage arrangement

Arrange a daisy chain with your conference phone and another Konftel 800 or connect Smart Mic expansion microphones. The maximum number of devices connected in a daisy chain is 3. One Konftel 800 phone acts as a central device (a "master") and one or two other units act as expansion devices (“slaves”).

The typical arrangements when the phone's coverage is expanded are the following:

• Master phone -- Slave phone
• Slave phone -- Master phone -- Slave phone
• Master phone -- Expansion microphone
• Expansion microphone -- Master phone -- Expansion microphone
• Expansion microphone -- Master phone -- Slave phone

Functions of the Master and Slave devices

When Konftel 800 acts as a master, it performs all its configured functions.

When Konftel 800 is in a subordinate position (a "slave"), it performs the following functions:

• Play audio received from the master device. The master phone defines the audio characteristics.
• Send its microphone audio to the master device.
• Receive and indicate mute state changes made on the master device.
• Send information to the master device when you tap [Microphone Muted].
• Send information to the master device when you adjust the volume on it.

You cannot make calls between the Master and the Slave devices. In a daisy chain, the Slave device follows the signal from the Master device to enter Sleep mode or Active mode. In a daisy chain, each phone is powered by its own PoE injector. The phone powers the Smart Mics when these are connected. The power available from each port is around 5 W.

Connection of the Slave devices to the Master phone

In a daisy chain, Konftel 800 disables all unused daisy chain ports during active calls to provide for the best possible audio experience. That means, that the time, when a Slave device activates, is dependent on the Master phone status as follows:

• The Master phone is in the Idle state. When the user connects an expansion microphone or a Slave phone to the Master phone, Konftel 800 immediately detects it, and the connected device becomes directly available for operation.
• The Master phone has an active call. When the user connects an expansion microphone or a Slave phone to the Master phone, the connected device becomes available for operation only after the call ends.

The same approach is applicable when the user disconnects and reconnects an expansion microphone or a Slave phone to the Master phone during an active call. In this case, the connected device also becomes available for operation only after the call ends.

Arranging a daisy chain

Use this procedure to arrange a daisy chain of one master Konftel 800 phone and one or two slave conference phones or expansion microphones.

Before you begin

If you arrange the daisy chain made of several conference phones, prepare the connection cables. The cables in the Daisy Chain kit are 5 and 10 meters long. You can purchase the Daisy Chain kit as an accessory. The cable of the Smart Mic is 3 m long.

Procedure

1. Connect the cable to the audio expansion port on the phone. There are 2 audio expansion ports on Konftel 800.
2. Connect the other end of the cable to the audio expansion port of the other phone. In case of expansion microphones, the other end of the cable is fixed in the device.

Expansion Microphone Firmware Upgrade

You can upgrade the expansion microphone firmware to the Konftel 800 firmware version when your Smart Mic has an older firmware installed. Regularly updating the expansion microphone firmware to match the phone firmware ensures the best possible audio performance.

The phone suggests an automatic upgrade of the expansion microphone firmware when you connect your Smart Mic to Konftel 800. You can connect one or two Smart Mics simultaneously. You can also initiate the expansion microphone firmware upgrade manually.

If you connect the expansion microphone to Konftel 800 during an active call, the upgrade does not start until the call ends.

During the upgrade, the phone rejects all incoming and outgoing calls and does not activate the Call Transfer feature. At that Konftel 800 indicates that it is Busy.

Upgrading expansion microphone firmware

Use this procedure to upgrade the expansion microphone firmware when the Smart Mic and your device have different firmware installed.

Before you begin

Make sure Konftel 800 is in Idle Mode.

Procedure

1. Connect the expansion microphone to your conference phone using the available audio expansion port. The expansion microphone LEDs flash red once.
2. A pop-up dialog window shows the following message: A connected microphone needs firmware upgrade. Upgrade now?
3. On the pop-up dialog window, tap Yes to start the upgrade.

The LEDs on the phone turn red to indicate that it is busy with the microphone upgrade. The expansion microphone LEDs start flashing green. The phone displays the Upgrade in progress message and shows the upgrade progress in percentage (0%-100%). When you connect one Smart Mic to Konftel 800, the phone shows the upgrade status for Smart Mic 2 as N/A.

Smart Mic 1: 10% Smart Mic 2: N/A

Optional: To cancel the upgrade, tap No. In this case, you postpone the upgrade until the phone reboots.

Result

If the upgrade is complete, the microphone LEDs turn off, and Konftel 800 displays the following message:

Upgrade in progress Smart Mic 1: Done Smart Mic 2: N/A

In 10 seconds, the pop-up dialog window hides, and the phone enters Idle mode. If the Smart Mic firmware upgrade fails, the microphone LEDs turn off, and the phone displays the Smart Mic 1: Failed message.

Upgrading two expansion microphones

Use this procedure to upgrade two expansion microphones connected to your device simultaneously.

Before you begin

Connect Smart Mic 1 to the first audio expansion port of your conference phone.

Procedure

1. Connect Smart Mic 2 to your conference phone using the second audio expansion port.

The LEDs on the phone turn red to indicate that it is busy with the microphone upgrade. The Smart Mic 2 LEDs start flashing green.

A pop-up dialog window provides the expansion microphones upgrade status in the following format:

Smart Mic 1: 20% Smart Mic 2: 10%

Optional: Terminate Smart Mic 2 upgrade by detaching the expansion microphone from the phone. In this case, you postpone the upgrade until you connect Smart Mic 2 again.

Result

When the upgrade is complete for Smart Mic 1 and Smart Mic 2 is still upgrading, the LED turns off on Smart Mic 1, and Konftel 800 displays the following message:

Upgrade in progress Smart Mic 1: Done Smart Mic 2: 86%

When the upgrade is complete for both microphones, their LEDs turn off, and Konftel 800 displays the following message:

Upgrade in progress Smart Mic 1: Done Smart Mic 2: Done

In 10 seconds, the pop-up dialog window hides, and the phone enters Idle mode. If the firmware upgrade for any of the expansion microphones fails, the microphone LEDs turn off, and the phone displays the message stating the Failed status of the corresponding Smart Mic.

Terminating expansion microphone upgrade

Use this procedure to terminate the expansion microphone upgrade. You can do it in the following cases:

• The phone has one Smart Mic 1 connected; or
• The phone has both Smart Mic 1 and Smart Mic 2 connected simultaneously.

Before you begin

Connect Smart Mic 1 and Smart Mic 2 to the phone and start the upgrade process for both expansion microphones.

Procedure

1. Detach Smart Mic 2 from the phone. Smart Mic 1 continues upgrading with the value for the upgrade progress being updated.

Smart Mic 2 upgrade dialog indicates an error and aborts the mic upgrade. Konftel 800 displays the following message:

Upgrade in progress Smart Mic 1: 50% Smart Mic 2: Failed

When Smart Mic 1 upgrade is complete, its LED turns off, and Konftel 800 displays the following message:

Upgrade in progress Smart Mic 1: Done Smart Mic 2: Failed

This message disappears in 10 seconds.

Optional: To upgrade Smart Mic 2, connect it to the conference phone and proceed with the upgrade.

Upgrading Smart Expansion Microphone manually

Upgrade your expansion microphone manually when it is convenient to you.

Procedure

1. Hold the [Microphone Muted button] on the Smart Mic while you connect the microphone cable, and keep holding the button for 5 seconds after you inserted the cable.

When you release the button, it flashes red one time and then starts flashing green to indicate that the upgrade process has started. The LEDs on the phone turn red to indicate that it is busy with the microphone upgrade. The upgrade process takes about 7 minutes. When the upgrade is completed, the microphone LEDs turn off.

Check the microphone version by tapping Settings > Status on the phone screen.
