Mitel Aastra and Telia VIP status information (Flexim) – Nepton Support

Nepton can send person's status information to Mitel Aastra and Telia VIP (former Telia Merex) phone systems. Both integrations send data to Flexim which then provides the data for the phone systems.

Definitions

Defining persons identifier

Persons identifier can be set by editing persons information in Employees - Person's information - Identifiers - Aastra. Both Aastra and VIP integrations use the Aastra-identifier field set in the identifier settings.

Defining event types

Event type codes can be set in working community settings, Worktime - Administration - Working Community Settings - Integrations - Mitel Aastra for Mitel Aastra integration and Worktime - Administration - Working Community Settings - Integrations - Telia Merex for Telia VIP integration.

Event type codes

Event type codes can be set according to the table below.

Code	Information
1	Meeting
2	In (equal to starting work)
3	Out (equal to ending work)
5	Travel work
6	Holiday / Work time shortening leave / Balance leave
7	Sick leave
8	Training
9	Work elsewhere
0	Out other reason (equal to ending work)
a	Lunch

Sending data

The Mitel Aastra host address and other settings can set in working community settings, Worktime - Administration - Working Community Settings - Integrations - Mitel Aastra - Configuration

The Telia VIP host address and other settings can set in working community settings, Worktime - Administration - Working Community Settings - Integrations - Telia Merex - Configuration

For both integrations, the maximum amount of statuses sent per minute is 100 submissions by default. Delay between sent status rows in milliseconds is 500 milliseconds by default. These can be changed in their respective setting fields.

Limitations

Employees with personnel number 0 are not included in the integration file

Technical operation of the integration

Statuses are sent to the specified server address as raw data, one status at a time. Information is sent via an opened TCP socket and the connection does not wait for a return message for the sent data.

Sent data

The integration is standardized and there is no need to make changes to the content. One status change is textual data separated by a tab character. Used character set is ASCII. The sent information is described below.

Information	Description
Start character	Start character is always an `STX` character (Start of Text), ASCII HEX `02`.
Event type code
Tab character
Person's Aastra identifier / employee number	Up to 11 characters long.
Tab character
Other reason code	Up to 3 characters long. Not used.
Tab character
Event end date	If the event has a known end date, it will be included. Format `DDMM`, for example `3105`.
Tab character
Event end time	If the event has a known end time, it will be included. Format `HHMM`, for example `1230`.
Checksum character	Checksum is only calculated for Telia VIP integration and won't be included with Mitel Aastra integration.
End character	End character is always an `CR` character (carriage return), ASCII HEX `0D`.

Expected response

Integration does not expect any response for sent person statuses. As long as writing to the open TCP socket does not fail, person status is considered as successfully sent.

Checksum calculation formula

The position of each character in the ASCII table is calculated and the integer value of all positions is added together. Only characters before checksum are checked.
The integer value of lowest 7 bits of the sum from previous step is retrieved.
If the integer value is less than 32, 32 is added to the value.
The resulting integer value is the order number of the checsum character in ASCII table.

PHP example:

<?php

function getChecksum(string $string): string
{
    $sum = array_sum(
        array_map(
            static function (string $chr): int {
                return ord($chr);
            },
            str_split($string)
        )
    );
    $sum &= hexdec('0x7f');
    if ($sum < hexdec('0x20')) {
        $sum += hexdec('0x20');
    }
    return chr($sum);
}
