Line Keys

The Yealink handsets that support multiple accounts such as the Yealink T22 can also use the Line keys to indicate multiple incoming calls instead of linking to different accounts. To set the Line keys to operate in this way, go to the [DSSKey] menu and select the Line Key settings. Set each of the Line keys to operate with Line 1.

Codecs

To configure the Codec settings to match the VigorBX 2000's Codec configuration, change these settings under the [Account] menu on the handset under the Codec settings:

Call Waiting

On handsets that support multiple Lines, the Call Waiting facility allows a phone to take other calls while there is a call in progress. This means that the handset will ring / beep to announce other incoming calls and the PBX system will not be able to perform the Busy action, such as going to Voice Mail, because the handset has not given a Busy response.

When Call Waiting is disabled, the handset will give a Busy response and the PBX can then perform the action specified in the Busy setting of the Extension Profile.

This is configured from the [Features] menu in the handset's web interface, under the General Information settings:

Voice Mail

Handsets with a Voice Mail button must have the number specified in the configuration to call this number. The VigorBX 2000's default Voice Mail number is 888, configure this under the [Account] menu in the Advanced settings to allow the Voice Mail button on the handset to work correctly:

DTMF

Dual-Tone Multi-Frequency (DTMF) signaling allows an IP phone to relay Touch-Tone key presses through different IP and PSTN call systems, for instance calling a Bank's Telephone banking service may require touch tone / DTMF to operate.

On the VigorBX 2000, the default DTMF setting to use is RFC2833 or Out-of-Band.

The setting is configured under the [Account] menu, in the Advanced settings. Configure the DTMF Type as RFC2833.

Call Pickup & BLF

The Call Pickup facility of the VigorBX 2000 system operates using a dial code of "*1" by default, this can then be used in two ways:

• Group Call Pickup: Dial the Call Pickup number and the handset can then pick up a call within the same Hunt Group
• Directed Call Pickup: Dial the Call Pickup number followed by the Extension or Hunt Group number to pick up that call

The Yealink handsets with Programmable keys that are located either on the side of the phone or linked to the screen can be configured to link to other extensions for calling or transfer and can be configured perform call pickup if there is a call in to the linked extension.

This also allows for the BLF (Busy Lamp Field) facility to view the status of that handset, such as whether the handset is on a call or receiving a call.

To configure this, go to the [DSSKey] menu on the phone, go to the Memory Key or Line Key sections (depending on the handset) and configure the buttons as shown:

• Set the Type to BLF to enable BLF operation, otherwise set SpeedDial
• The PBX Extension or Hunt Group number in the Value field
• Line number linking to the account on the phone
• Extension number should be entered as "*1" to enable call pickup
