How Quality of Service can affect In VoIP Calls What is Quality of Service Quality of Service (QoS) is defined as ability of network to access number of maximum bandwidth and deal with other network elements like error rate, uptime and latency which effects the performance. There are several meaning of Quality in networking,in simple way we can say that Quality is some thing in which speak clear voice,listen clearly without any noise. Service in VoIP means services which offered communication facilities to their consumer. Factors Which Affect Quality of Service In VoIP Call In start quality of VoIP was not good. It is the big Hallmark on VoIP quality. But with the passage of time there has been seen lot of improvement in voice quality of VoIP calls. Still many people prefer traditional analog communication over the VoIP. VoIP is mostly used in IP network. It carries different type of traffic like video and voice traffic,carrying data. Some time network resources are congested it become the cause of low quality VoIP call. For voice service provider it is important to use quality of services in their network for VoIP traffic. There are number of factor which can effect the quality of VoIP traffic. Some of these i discussed below. Delay We know delay as process of VoIP traffic which reached from one endpoint to another endpoint. It is also called end-to-end delay. We can measure delay two way. We can measure it through one way or we can measure it through round trip. Acceptable one way delay voice is 150ms according to ITU G.114.A delay which is greater than 150ms cause poor voice quality and bad effect on user experience. Jitter Jitter is variation in delay from one endpoint to another endpoint over the time. Jitter cause the voice degraded if it varies too widely in VoIP communication. VoIP network usually deliver the VoIP traffic at constant rate by buffering at the endpoints. If jitter is too high its become difficult to buffer control it at endpoints finally the result is poor voice quality. Packet Loss Packet loss can be define as number of dropped packets in the data path during carrying the VoIP traffic from one endpoint to another endpoint. Usually it is consider that three percent is bearable limit for good voice quality. If this limit is increase from 1.5% it causes the poor voice quality.
While communicating with my new customers in last 10 years, The top questions that I faced, were related to Voip Provider . The customer with previous experience with voip face no issues selecting and configuring a Voip Provider however It was really a difficult task for new customer to find out a suitable Voip Provider for his needs . A customer with no background in Voip industry hardly grasp the basics of Voip and consequently he faces difficulty to select a proper Voip Provider. Finding a proper Voip Provider involves number of technicalities like protocol selection, codec selection, number of concurrent channels , call generation rate, quality issues and compatibility with application. Below we will discuss these issues and will guide new comers to find out a proper voip provider for their needs. Scope of this article does not allow me to indulge in Voip Basics therefore I am providing related link that will help reader to know more about Basics of Voip. http://www.voip-info.org/wiki/view/What+is+VOIP Who Are VoIP Providers: We usually known VoIP provider as VoIP service provider which offer VoIP Internet telephony solutions to residential and commercial customers. They also provide the services and hardware to subscribers under monthly rates. The mechanism of call transmission of VoIP provider is different from traditional Public Switched Telephone Network (PSTN). VoIP provider utilize packet-switched telephony to transmit calls over the Internet it is different from the circuit switched telephony. Types of Voip Providers Voip Providers can be divided into following three main categories 1. Residential Voip Residential Voip is basically resembles to traditional home phone service where a per-configured IP phone or adapter connected with internet to provide home phone services whereas traditional home phone services connected with PSTN Lines . 2. Business Voip A Business Voip can be hosted PBX , On Premises PBX or any other kind of Voip Services offered to commercial users. 3. Wholesale Voip A Wholesale Voip focused to offer services to services providers or customers that interested to deal in bulk Voip like wholesale DID buying , wholesale sip termination or sip origination services. Consider Key Factors Before Choosing VoIP Service Provider. As our focus is wholesale Voip provider therefore we will consider important points that you should keep in mind while finding and selecting a wholesale voip provider for your needs. 1. Capacity requirements. First you need to estimate the maximum number of concurrent calls that your system can process at a time and after finding out the number of concurrent calls, you need to confirm and demand from voip provider that whether he will fulfill our capacity requirements. It is also called concurrent channels capacity or number of ports required . As an example , if your have setup a system with 100 concurrent channels / ports then said setup will be capable to dial out 100 outbound calls at a time. 2. Protocol supported You also need to take care of compatibility issues and need to find out whether technology behind your Voip Provider and Your system is compatible with each other means if your have SIP compliant setup then your Voip Provider also have SIP compliant setup. In telecommunications, a communication protocol is a system of rules that allow two or more entities of a communication system to communicate between them to transmit information via any kind of variation of a physical quantity. Following are main protocols used in VoIP SIP, Session initial protocol SIP: - Sip is most widely used protocol in Voip industry . SIP offered by IETF and now it is defacto standard of Voip world. SIP treats signaling and data differently also routes them with different routs. IAX/IAX2 – Inter Asterisk Exchange Protocol was offered by digium and it uses both signalling and data link on same trunk H323: H323 is ITU Voip protocol. 3. Codecs supported Codec selection is also play important also both Voip Provider and your setup needs to support same codec to communicate with each other that is why you have to confirm provider about required codecs . Codec are used to convert our analog voice signal into digital data from transmission from source to destination through internet and these digital data signal reaches destination, these are again converted back to analog signal using codecs and we hear the voice message. G.711 ulaw (supported in US) , High quality, Low processing but high bandwidth consumption as bandwidth consumption will be 64 kbps per channel . G.711 alaw ( supported in Europe) ,High quality, Low processing but high bandwidth consumption as bandwidth consumption will be 64 kbps per channel. GSM GSM is basically a cellular standard codec available free, average quality and low bandwidth requirments 13 kbps G.729 needs licensing to be use in production. High quality, High processing requirements but lower bandwidth needed about 8 kpbs per channel. 4. CPS CPS stands for call per second, it is basically call generation rate and you have to verify from provider that your voip account does support required CPS rates. As an example , a 100 concurrent calls setup may have 10 cps. It is also required to match calls per scond rate of Voip Provider connection with our system, As an example if we have 10 cps account from a voip provider then we should also have full capaicty 5. Origination or Termination If We are calling other numbers from our system , we will required a Voip Porivder Account that offer Termination services however if others are calling towards our setup then we need origniation services to receive incoming calls. 6. A-Z range A-Z means alphabetically all countries supported , A Voip Provider with A-Z termination means all destination across the globe are supported and we can call all countries . 7. Competitive call rates Also you have to compare call rates of Voip Provieder for your required destination, Voip provider will differ with pricing and you have select best option keeping in mind both quality and price. 8. Quality of Service (QoS) Latency / Jitter and Packet Loss QoS (Quality of Service) is a major issue in VOIP implementations and we have to take all measures to to guarantee that packet traffic for a voice will not be delayed or dropped due interference from other lower priority traffic. Things to consider are Latency: Delay for packet delivery Jitter: Variations in delay of packet delivery Packet loss: Too much traffic in the network causes the network to drop packetshttp://www.voip-info.org/wiki/view/5+Curable+Causes+of+Poor+VoIP+Call+Qu... 10. Fax support If there is need to add support Fax over IP in system then you have too verify from provider that whether it support Fax either G.711 pass through or T.38 . T.38 fax support is more reliable and it is recommended when compared to G.711 pass through . 11. Internet Bandwidth A G.711 Voip call takes 87 kbps data rate and we have to keep in mind while setting up a Voip based system.

Converting SIP trunking from traditional analog system means to simplifying your organization’s telecommunications,save expense and enhancing real time communication in your business. Save Cost By using SIP trunking you can save your cost. It eliminates the need to purchase the local PSTN gateways,Primary Rate Interfaces (PRIs),Basic Rate Interfaces (BRIs).SIP trunking provide easy way to extend your system over IP and save cost. It save you from purchasing expensive hardware. Save Long distance Service Cost Another benefit of Session Initiation Protocol (SIP) is to save long distance telephony cost because SIP trunk connection cost is less as compare to traditional analog services. Pay For The Number Of Lines By using SIP trunking you have freedom to pay only number of lines/channel you are using rather than to bound to excess analog lines or partially-used T1s and PRIs. It allow companies to reduce cost of communication by utilizing exact needed resources. Direct Inward Dialing number DID or we can also call it phone number is less expensive when we buy it with SIP trunk as campare to purchase traditional phone companies. When we purchase it from traditional phone companies they implement some charges like charges of maintenance,shared physical channel. But with SIP you can escaphe such types of charges.
