Introduction

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

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.

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.

Only Numbers

The Only 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 URL

The Numbers With URL schema pairs phone numbers with associated URLs for screen pop. 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 Name and Source

The Numbers With Name and Source 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

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
