What is VoIP ? Is based on package switch networkVOIP is carried over the internet network, using

internet protocol (IP) technology. The voice call is digitised, and broken up into a

series of packets. The packets are then routed over the internet network to the final destination.

The packets are reassembled at the end, and delivered as a voice call to the called party.

Individual packets may take different routes, which are allocated by a series of routers.

The routes are shared with other packets (which may carry other voice calls, data streams or video streams), thus making much more efficient use of the network.

However the packets may be delayed at individual routers if there is congestion on the route.




Package Switch Network




Types of VoIP Three types of VoIP calls:

1. VoIP 2 VoIP calls • Calls between VOIP terminals that are

both linked to the internet. • The call does not leave the internet, and

usually there is no charge for the call.




2. VoIP to PSTN calls• Calls from a VOIP terminal to a terminal on the PSTN. • The caller dials the PSTN number, and the call has to leave the internet at a gateway between the internet and the PSTN. • It is then switched to its destination on the PSTN. • Some form of charges are involved • Example, Skype

3. PSTN to VoIP calls• In this case a number has to be allocated to the VOIP terminal, which the caller uses to make the call. •The call is switched through the PSTN to the gateway, and then routed through the internet to the appropriate VOIP terminal. • Such calls are charged




Terminal equipments used for VoIP services• Personal computer with a headset or with a microphone and separate loudspeakers;•Laptop with integrated speakers and microphone; •Traditional fixed or cordless telephone connected via a special adapter to a LAN or to a USB socket on a PC;•Special purpose handset or telephone that connects to a LAN, or WiFi or the USB socket on a PC; •Dual mode mobile handset that can use both WiFi and GSM/3G networks.

or technologically neutral?• VOIP is a technology based solution which

enables the provision of voice services over IP networks.




Numbering• Which numbering system to be adopted;• Should existing E.164 number be issued and if so, in which ranges?;• Should the numbering be based on geographic

or non-geographic




Emergency Service• Should access to Emergency services be made mandatory ; Interconnection• What type of interconnection principle to be adopted; Quality of Service• Should ITU recommended standard (Y.1541) for

VOIP services be applied;




Recommendation for SATRC Working GroupStudy should aimed at : Developing a harmonized regulation pertaining

to VoIP within the SATRC region Priority to be given to issues, such as

Interconnection, QoS, Numbering, Access to Emergency services

Looking into developing a liberalized policy concerning with VoIP in order to facilitate the growth of such services
