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:
- Numbers with names and sources (default format)
- Alternative schemas:
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:
| Number | Name | Source |
|---|---|---|
| 441234567890 | Oliver Bennett | EuroBiz Networking Event 2025 |
| 4915123456789 | Mia Fischer | TechConnect Europe Summit |
| 33123456789 | Élise Dubois | GreenFuture Sustainability Email Campaign |
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:
| Number | URL |
|---|---|
| 441234567890 | https://example-business-uk.com/contact |
| 4915123456789 | https://example-germany-shop.de/signup |
| 33123456789 | https://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:
| Number | Name | URL |
|---|---|---|
| 441234567890 | Oliver Bennett | https://example-business-uk.com/contact |
| 4915123456789 | Mia Fischer | https://example-germany-shop.de/signup |
| 33123456789 | Élise Dubois | https://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:
| Number | Priority |
|---|---|
| 5511998765432 | 21 |
| 5491134567890 | 0 |
| 573045678901 | 13 |
| 59891234567 | 13 |
