7 Steps for successful VoIP

The original name of David Sims's article is "seven successful VoIP services in seven steps", it aims to help ISP or traditional telephone companies respond to the requirements of enterprises interested in VoIP services. However, this Guide applies to anyone interested in VoIP, even if their enterprise scale is small. Few of these steps involve enterprise-level implementation. They provide a good reference for negotiating VoIP services with ISPs or telephone companies.

Step 1: Integrate the Customer Service Network

Any successful business is built on a comprehensive understanding of customer needs and behaviors, product uses and attractiveness, and the use and status of internal product resources. VoIP service providers can gain competitive advantages from the collection of comprehensive customer service networks. Reliable data access and performance measurement, combined with powerful tools, can make information available to every department of the service provider organization, it is also the cornerstone of building a comprehensive business and making the business successful.

Step 2: Focus on the speech quality that can be felt

The only way to obtain detailed knowledge about the relationship between voice server quality and network characteristics is to track network and service behavior with common information. The time-varying behavior of an IP address means that you need to continuously monitor and analyze the voice service standards and network performance standards to ensure that the network capabilities fully understand must meet the quality of long-distance telephone services.

Voice quality monitoring parameters include: listening quality, that is, the definition of speech at one end), the tone at one end, that is, the capability of the terminal device, and the ability to hear sound without ECHO ), as well as the quality of conversation, it refers to the full duplex capability of two users when talking ). The overall speech quality is the synthesis of the above parameters.

These parameters are quantified using the average opinion score mean opinion scores, MOS), which are provided after a certain number of individual tests or automated test procedures are tested, it also has a great relationship with the language, age, and gender of individual testers. The MOS value range is from 1 worst) to 5 best). The MOS value of the long-distance call in the PSTN network is between 4.0 and 4.5. In the case of a GSM call, it is approximately 3.6.
Step 3: new IP performance specifications

In the line exchange world, server-centric specifications built on the basis of signal analysis are already familiar to everyone. Important parameters of the specification include the call establishment time, network efficiency ratio, and successful call access rate. NER, CST, and SCCR are widely used to define the service level, because they all reflect the user's feelings. The Network monitored by the System-generating and storing such performance specifications at the same time-must be flexible enough to view the entire network or a desired subnet.

Step 4: Comprehensive Monitoring

The next generation SIPShort Irregular Pulse, with no rule short Pulse) terminal includes Localization support for reporting signals, VoIP specifications including CST, CSR and MOS) and error feature provider RTCP-RFC.3611. This allows service providers to automatically upload information from end users to provide supplementary monitoring of core networks.

Therefore, a system capable of automatically associating terminal data based on relevant network information can immediately report any device fault or insert service quality to service providers. Passive monitoring of end-user devices can be successfully supplemented by the active test solution, which continuously verifies the service quality and availability through predefined service scenarios.

Step 5: Activate internal/external SLA usage

As long as the weakest connection exists, the entire link cannot be strong. This means that the quality of service customers feel depends on the quality of all networks, including the network of service providers and the networks of the connected partners. Continuous monitoring of service quality (QoS) and new network capabilities are not only useful for various SLAs, but also for standardized performance and SLA reports, or for service providers to determine new internal service targets, as well as the basis for negotiating a favorable agreement with the interconnection partner.

Step 6: differentiate the services you provide

To combat ARPU users' monthly bills) and gain a stronger competitive advantage, service providers need to expand new integrated voice and data services. The unified messaging service and different types of instant messaging services can be widely used. Two examples of integrated services are provided. In the future, these services will penetrate with new services to ensure high customer satisfaction rates.

Step 7: Automated cheating and Spam Detection

A network-wide monitoring system should provide a real-time continuous monitoring of streaming data, which can provide all the required information and detect the undesirable behavior. The "fingerprint recognition" function is achieved by 24-hour network load check, authentication data, and different types of traffic distribution data, and a picture of normal network behavior is provided.
