VigorBX 2000 - How to use a VTech IP Phone with the IPPBX

The VTech IP Phones such as the VTech VSP725A have configurable Feature Keys that can perform different functions. The top Feature Keys are primarily designed to be used as Line keys to view incoming calls.

To set the Line keys to operate in this way for a single account, go to the [System] menu and under Programmable Keys, select [Feature Keys 1] to change settings for the first set of Feature Keys.

Set the Type to Line and select Account 1, then click Save to apply that change.

The VTech IP Phones such as the VTech VSP725A have configurable Feature Keys that can perform different functions including BLF (Busy Lamp Field), which can view the state of another extension and indicate when that extension is on a call, is receiving a call or is otherwise unavailable.

To set up the Feature Keys to perform BLF functions, go to the [System] menu and under Programmable Keys, select [Feature Keys 1] to change settings for the first set of Feature Keys.

Please Note that the top Feature Keys (depending on the max supported lines on that handset) are primarily designed to be used as Line keys to view incoming calls and are not used for BLF.

Set the Type to BLF, specify the Extension or Hunt Group number in the Value setting and select Account 1, then click Save to apply that change.

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

These can be dialled manually from a handset to pick up a call without any configuration needed on the handset.

Once a Feature Key on the handset is configured for BLF, the handset can be configured to perform Call Pickup automatically when pressing that BLF key (for instance to pick up a call to that extension number) by going to [System] settings, select [SIP Account Management] > [Account 1] and scroll down to the Busy Lamp Field settings:

Specify the Remote Pickup Code as the Call Pickup number configured on the PBX system and save those changes to allow Call Pickup to work with BLF Feature Keys.

To configure the Codec settings to match the VigorBX 2000's Codec configuration, change these settings under the [System] settings, select [SIP Account Management] > [Account 1] and scroll down to the Audio settings:

Configure the Codec Priority as shown in this list to ensure compatibility with the PBX system.

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 [System] > [Preferences] menu in the handset's web interface:

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 [System] settings, select [SIP Account Management] > [Account 1], scroll down to the Feature Access Codes settings and configure the Voicemail number:

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 [System] settings, select [SIP Account Management] > [Account 1] and configure the DTMF Method as RTP Event:
