Meanwhile on the IDD service, telecommunication companies should have a IDD license given by telecommunication regulatory
Voice over IP (VOIP) can be done by using existing network infrastructures and insert one or more new network element for voice compression purpose. To have Voice over IP (VOIP) service, telecommunication companies should insert/deploy network infrastructures such as;

1. Voice over IP (VOIP) gateway

Voice over IP (VOIP) gateway responsible to handle all international calling services were dialed by subscribers. The main function of Voice over IP (VOIP) gateways are compressing the voice, routing the call, digit number translation policy and change the packet to IP base. Voice over IP (VOIP) gateway retrieves subscriber’s call from Mobile Switching Centre (MSC) and the process the call before deliver it to the destination number. Voice over IP (VOIP) gateway will generate the call detail report (CDR) when a call is established between source number (A number) and destination number (B number)

2. Internet bandwidth

Voice over IP (VOIP) service is internet protocol (IP) bases packet which mean that call will be delivered to destination number to the IP packet. To deliver the Voice over IP (VOIP) service, telecommunication companies require international internet bandwidth where the calls will come and go. Telecommunication companies used to already have international internet bandwidth either they leased from Internet Service Provider (ISP) or they build by their selves for many purpose. It means that no issue on the international internet bandwidth while telecommunication companies plan to have international internet bandiwdht

3. International Voice over IP (VOIP) partner

Telecommunication companies than need international Voice over IP (VOIP) partner that responsible to the end of destination number. More often, international Voice over IP (VOIP) partner will have another Voice over IP (VOIP) partner as well to deliver the call to destination number

The benefit of Voice over IP (VOIP) service is cheap tariff rather than IDD service. Voice over IP (VOIP) service is quite easy to be deployed rather than IDD service which require dedicated international link gateway with high capacity. Voice over IP (VOIP) service also need less investment rather than IDD service.

The things need to be added to fulfill VOIP service is international internet bandwidth and international connection which can lease to the provider or deploy by their selves. They also need to install VOIP gateway to carry out the traffic

There are two kind of international VOIP services they are Outgoing and Incoming VOIP services but they more often to serve outgoing VOIP only

1. Outgoing VOIP service

It means that subscribers will be allowed making international call to any countries by dialing with certainty prefix code. This service is valid to only their subscribers. in order to allow subscribers from another telecommunication company to user your International call service you should have International Direct Dial (IDD) service. To have outgoing VOIP service, Telecommunication Company should cooperate with International VOIP provider which will forward your VOIP call to destination number. To have more various charging, telecommunication company could connect to several VOIP partner which offer various price

2. Incoming VOIP service

Incoming VOIP means that Telecommunication Company will permit calls from any country to go through their telecommunication network and could be delivered to any destination number at different telecommunication company. It means that you are act as interface gateway between B number which may come from any country to A number which may your subscribers or from another telecommunication company.

To enable Incoming VOIP, Telecommunication Company should cooperate with VOIP partner which allowing incoming call and promote this service to people all around the world. Telecommunication Company did not to add more network telecommunication to enable incoming VOIP service. With the same network infrastructures, they only need to add more routing configuration to the VOIP partner gateway. More partners there will be more routing configuration that should be added

From subscribers’ view, the different between both VOIP and IDD service is while they make a dial session. VOIP service is valid to their subscribers only and subscribers should dial with additional prefix. Meanwhile, IDD service is valid to any subscribers from any telecommunication company with certainty prefix number which already given by regulatory institution.

It is different with IDD service, while Telecommunication Company decides to build a VOIP service, there will be some network infrastructures needed to be inserted to the current one. VOIP service is running on the existing network, telecommunication company just need to make sure that the call was delivered to the destination at abroad and conversation happen between calling and called number. Generally, the new network infrastructures that needed are;

  1. VOIP gateway
  2. International Link/Bandwidth
  3. International VOIP partner

The international call from subscriber will forwarded from Mobile Switching Centre (MSC) to VOIP gateway and digit translation is happening here. This new digit number will be encapsulated to the IP base packet and will be delivered to the International VOIP partner. VOIP gateway responsible to covert traditional call bases (ISDN and Signaling) coming from subscriber to the IP base packet.

Since VOIP service is international call base, telecommunication company should deploy international link or bandwidth to deliver and retrieve a packet. It is like a bandwidth needed by mobile internet service.The international link could be dedicated E1 transmission that will be terminated from Telecommunication Company to the international partner. Usually, Telecommunication Company prefers to provide internet bandwidth to deliver the VOIP traffic since they can insert it to another service which requires internet bandwidth as well such as mobile internet service .

Telecommunication Company did not deliver the VOIP traffic to the destination number directly. The international call will be forwarded to their international VOIP partner at abroad and let them deliver it to the proper destination number. International VOIP partner may forward the call to the destination number directly through VOIP service as well or they will forward it to their partner as well. It is depending on the level of international VOIP partner has been chosen by Telecommunication Company. Telecommunication Company also can connect their international call to several International VOIP partner to distribute various traffic scenario. This scenario usually was applied to give various tariff calls to certainty countries
