Guide to Jola International Numbering v1.4


1.    Introduction

Jola offers international numbering for SIP Trunk and Teams Direct Routing services. We cover provisioning and numbering in over 180 countries with competitive outbound and inbound calling rates.
 
Whether you are interested in purchasing or porting international numbers, this guide will help you understand what requirements must be met and advise you what services might be needed.

 
 
2.    Definitions:
 
Country of origin – The country which holds the number or range in question.
 
In-country dialling – Using the international number to call a number within the country of origin. Some countries, e.g. France, do not permit international carriers to provide French numbers that can make outbound calls to French numbers.
 
Inbound Calling – The ability for a number to receive calls.
 
Outbound Calling – The ability to make outbound calls.

Inbound Calling Service – A product that allows the customer to represent an international number to receive and make calls.  
In those countries where in-country dialling is NOT prohibited or restricted, outbound calls including to the country of origin, are included in this service.


Two-way Calling Service – A product that allows for a number to receive and make outbound calls. This includes the countries where in-country dialling is normally restricted. Not supported in all countries.

International Emergency Services – Provides the ability for in-country breakout for the purpose for emergency services access.


3.    Purchasing and porting international numbers

 Please read the following steps that need to be considered when purchasing or porting an international number:
 
3.1.        Documentation and requirements
 
Requirements placed by the country in question on the purchase or porting of international numbers are usually country and region specific. Depending whether the number is ported or activated, Jola will require information on how the number is/will be used, location of the user as well as the documentation needed to proceed with the request.
 
The documentation required might be in a form of utility bill, proof of residence, or certificate of business.

 Once a request for international numbering purchase/port is sent, we will send you a list of documentation needed and restrictions that must be met.
 
3.2.        Inbound Calling Service and Two-way Calling Service

 
Inbound Calling Service is a product that allows the customer to represent an international number to make and receive calls.

In-country dialling is where an International number is used to call a number within the country of origin.

In some countries in-country dialling is prohibited (outbound calls into country of origin are not possible but all other outbound calls are). Using France as an example, it is not possible for International carriers to provide French numbers which are used to make outbound calls to other French numbers (but please see Two-way Calling Service below).

The current list of the countries that prohibit in-country dialling is below but be aware that additional countries could impose restrictions and we may not get any warning (e.g. Singapore did not have any restrictions in place at the beginning of 2021).

 
·       Australia

·       Bahrain

·       France

·       Lebanon

·       Malaysia

·       Singapore

·       Switzerland

·       USA

In the countries listed above, if the customer needs  to make outbound calls to country of origin, we can provide a Two-way Calling Service. This product allows a number to receive and make outbound calls.  This service is not supported in all the countries, so please contact your Jola Account Manager to confirm if it’s available.

 
3.3.        Emergency Services

International Emergency Services provide the ability for in-country breakout for the purpose of emergency service access.

Emergency Services can only be provided with the Two-way Calling Service (with exception of those countries where Emergency Services are not available).
