    This article contains descriptions of the data structure schemas supported for Dialer campaign CSV file format calling lists.

    Introduction

    Outbound Dialer supports three methods of importing calling lists into an outbound campaign:

    This article provides an overview of the supported data schemas for CSV and XLSX file formats. The following schemas are covered in detail:

    Information

    After adding your calling list, Dialer reviews the numbers to ensure their validity and remove any duplicates. Invalid and duplicate numbers are compiled into a downloadable CSV file. Additionally, you can download the final calling list that Dialer will use for the campaign.

    Numbers with names and sources

    The Numbers with names and sources schema includes phone numbers along with contact names and source details. It is the default contact list format. The file should have three columns: phone numbers in E.164 format in the first column, contact names in the second column, and source names in the third column.

    Example:

    NumberNameSource

    Other calling list formats

    This section describes the alternative calling lists formats that you may request from your Voiso representative, premium support channel, or by email at support@voiso.com.

    Numbers

    The Numbers schema specifies a list containing only phone numbers. The file should have a single column of phone numbers formatted in E.164.

    Example:

    Number
    85291234567
    918765432109
    628123456789

    Numbers with URLs

    The Numbers with URLs schema pairs phone numbers with associated URLs. The file consists of two columns: phone numbers in E.164 format in the first column and fully qualified URLs in the second column.

    Example:

    NumberURL
    441234567890https://example-business-uk.com/contact
    4915123456789https://example-germany-shop.de/signup
    33123456789https://example-restaurant.fr/reservation

    Numbers with names and sources (URLs)

    The Numbers with names and sources (URLs) schema is similar to the Numbers with names and sources schema, but the third column contains a fully qualified URL.

    Example:

    NumberNameURL
    441234567890Oliver Bennetthttps://example-business-uk.com/contact
    4915123456789Mia Fischerhttps://example-germany-shop.de/signup
    33123456789Élise Duboishttps://example-restaurant.fr/reservation

    Numbers with priority

    The Numbers with priority schema is a two column structure with the contact phone number in E.164 format in the first column and a priority value in the second column that represents the calling priority of the contact. Priority ranges from 0 to 1000, where lower values equal higher priority. 0 is the highest priority.

    Example:

    NumberPriority
    551199876543221
    54911345678900
    57304567890113
    5989123456713
