Making Outbound Calls 

When sending calls from a SIP trunk or from your AVOXI Webphone you should dial all numbers in E.164 number formatting.  This is a standardized numbering plan for the worldwide public switched telephone network (PSTN). It was developed so that associations around the world would have a standard format in which to express telephone numbers and is the primary standard that AVOXI uses. The format is the country code plus the number subtracting any preceding zeros. E.164 formatted phone numbers are limited to a maximum of fifteen digits.  

Warning CLI Limitation:  Outbound Traffic must be presented with a South African CLI by the customer or an International penalty of $0.25 per internal service will be imposed.

How to advertise and dial a South Africa TrueLocal Number

South Africa switched to a closed numbering system effective 16 January 2007. At that time, it became mandatory to dial the full 10-digit telephone number, including the zero in the three-digit area code, for local calls (e.g., 011 must be dialed from within Johannesburg). Area codes within the system are generally organized geographically. All telephone numbers are 9 digits long (but always prefixed by 0 for calls within South Africa), except for certain Telkom special services. When dialed from another country, the '0' is omitted and replaced with the appropriate international access code and the country code 27.

Calling Emergency Services 

Calling an emergency service differs from country to country, with many countries using multiple emergency numbers depending on who you want to reach.  While in many countries, simply dialing 112 (used in Europe and parts of Asia) or 911 (used in the United States) will instantly connect a caller to emergency services this is not the case in South Africa.

Porting Overview

Number porting is the process of transferring an existing number to a new carrier. This gives businesses the ability to retain their numbers, which can then be used as an outgoing CLI.  AVOXI's local licensing and direct subscription to the Number Portability Company (NPC) makes porting in South Africa uncomplicated and easy.  In addition, all porting is carried out in line with the Electronic Communication ACT, No 36 of 2005 for Number portability, Gazette 30089, dated 13 July 2007.
