1. VoIP
- Telecommunications Regulation (Act 36/1999) that supports the competition.
- Telecommunications technology developments especially those based on IP is very fast and getting cheaper.
- Internet usage menakjupkan developments around the world.
- Community desire for Telecommunications service quality and cheap.
2. Understanding VoIP VoIP (Voice over Internet Protocol) is another name for Internet telephony. Internet telephony is the hardware and software that allows Internet users to the transmission media phone calls. The quality of Internet telephony is not yet as good as the quality of a direct telephone connection. Voice over Internet Protocol (VoIP) is a technology capable of passing voice traffic, video and data in the form of packets through the IP network. In VoIP communications, the user through a phone connection through the terminal in the form of a PC or telephone. Terminal will communicate with the gateway via the local telephony. Relations between the gateway through an IP network.
3. Why VoIP Voip, or Voice Offer Internet Protocol is one form of Internet-based Telecommunications Technology, if previously used the Internet in just to Transfer Voice Input or with one of the benefits of VoIP is that we can push the capacity up to 11 kbps kbps and the practice could be in the press become even smaller, far different when compared with technology Wired (cable) 64 kbps, the difference is we can take advantage of lower cost to transfer the Voice. The advantage of using VoIP:

The advantage of using VoIP:
- Pulse is a pulse that is used Client Postpaid (Post paid) regardless of pulses used is flexible.
- Subscribe system is advantageous because the client will get the convenience of communication without having to build infrastructure or VoIP network, with efficient pulse every call.
- VoIP has been received by various businesses, even in the Regulation of VoIP has been set by the government, so this is a VoIP service in LegalPelanggan not wear anything other than the cost of toll fees that have been in use made the call.
- Clients end of each month to get all the call records (call report) along with the bill.
- Clients can perform testing services use the Save for a total deemed profitable.

5. VoIP variant a. PC to PC (YM!, Skype, Merdeka, ...) b. Telphone number Telphone (requires Geaterkeeper, ITG) c. Telphone (Hp) to the Operator
6. Quality Of Service (QoS) of VoIP QoS can be defined as the ability of networks to provide better service to certain traffic. QoS on VoIP networks used to provide better service for voice traffic (seek delay and low jitter). There are several techniques associated with the implementation of QoS. Generally consist of:
a. Classification of packet The basis of the use of QoS is located on the capabilities of the device in the network to identify each type of packet. This identification process is called packet classification. Once classified the package will be marked (mark) by way of set bits in the IP header contained.
b. Queue management Without the use of QoS, queuing on the network are conducted using antraian discipline FIFO (First In First Out), ie every packet that comes first on a network interface will be transmitted first. In this case allows voice traffic to wait a long series of data packets and create a huge queue delay. To provide QoS in the network there is some queue discipline that can be used.
c. Packet fragmentation. Fragmentation is solving big packages into smaller packages. This is done to minimize the excessive delay serialization package. In the worst case queue serialization packets to the WAN link, the voice packet must wait in the back of the packet data, the longer the data packet delay of VoIP packets bigger. This condition is called blocking. To prevent this condition is withholding the data packets are long (fragmentation), and VoIP packet potongan-potongan/fragmen inserted between data packets (interleaving).
7. Legal / Illegal? a. There must be permission from Postel as a provider of VoIP services in Indonesia. b. Legal if used for Internal Corporate and Personal use (do not connect with the operator). c. Government monopoly operator.
8. VoIP Issues a. Bandwidth b. Network c. Security d. ITG Technology Solutions e. Training f. Policy
9. VoIP Implementation a. At this permission is only granted to operators of VoIP services of basic telephony / voice of Telkom, Indosat and SETELINDO. b. Other operators to get permission to have entered the MCC (Pattern of Cooperation) with Telkom, Indosat and / or Satelindo. c. Strive balancing tariffs Local, long distance, and SLI. d. Once ready dubuka perceived competition, VoIP can be given without the permission of MCC with Telkom, Indosat, and / or Satelindo
