Mitel

The DuVoice 7.00 can link to a Mitel 3300 PBX using either a serial connection or a TCP connection where the PBX is the server/host. This link uses the protocol and features listed in the table below:

This page is used to configure the 7.00's link to the Mitel.

The settings are grouped into three categories: Network, Serial and Overrides, plus one general setting. Configure the settings as needed and then click OK to save your changes and close the dialog. Or click Cancel to discard any changes and close the dialog.

General Settings

SettingDefaultDescription

If it is a TCP link, leave the box unchecked.

Network Settings

SettingDefaultDescription
IP or DNS Name(blank)Enter the IP address or DNS name for the PBX.
TCP Port number5001Enter the port number to listen on for connections from the PBX.

Serial Settings

SettingDefaultDescription
COM PortCOM1Select the COM port to which the serial cable is connected.

Options include: COM 1 through COM 255. Which ports are actually valid depends on the hardware installed (or connected) and the Windows configuration.
Baud rate9600Set the value to match the setting on the PBX.

Options include: 300, 1200, 2400, 9600, 19200, 38400, 57600, and 115200.

Options include: 5, 6, 7, and 8.
Stop bits1Set the value to match the setting on the PBX.

Options include: 1 and 2.
ParityNoneSet the value to match the setting on the PBX.

Options include: None, Odd, Even, Mark, and Space.

Overrides

SettingDefaultDescription
ChecksumDisabledMust be set to disabled because the Mitel protocol does not use checksums.
ENQ with ACKEnabledDetermines if the voice server always responds with ACK when an ENQ is received. If disabled, the server re-sends its response to the last message received from the PBX.
\\Should be set to enabled because the Mitel protocol expects an ENQ to be sent and acknowledged prior to sending a message.
Send ENQEnabledShould be set to enabled because the Mitel protocol expects an ENQ to be sent and acknowledged prior to sending a message.
Disable ACK-NAKDisabledMust be set to disabled because the Mitel protocol requires ACK-NAK responses.
Polling Interval300Enter the number of seconds to wait between polling (keep-alive) messages. Ideally, this should not be less than 60 seconds unless the PBX requires it.
Transmit Delay500Enter the time, in milliseconds, that the voice server should wait after sending a message (and receiving the ACK response) before it can send another message.

The default is 500 ms (half a second). If the PBX is getting overwhelmed, you can increase this value to artificially slow the pace of message traffic.
Idle timeout30Enter the maximum time, in minutes, the port can be idle before the port (or the PBX link service itself) is reset. A port is considered idle if no input is being received.

The purpose of this feature is to force a port reconnection if it appears the link has been dropped or is otherwise not functioning even though it otherwise appears to still be connected.

If polling is enabled, this must be set to a value larger than the polling interval. Note, however, that this value is specified in minutes while the polling interval is specified in seconds.

Set to 0 if you wish to disable this feature.
