Section 1 Introduction VoIP is simply the transport of voice traffic by using the Internet Protocol (IP). It is a technology that allows you to make voice calls over a broadband internet connection instead of a regular phone line. In VOIP your voice is converted into a digital signal that travels over the internet. If you are calling a regular phone number (i.e. on a PSTN), the signal is converted to a regular telephone signal. Numerous IP based PBX solutions are in place and more are being deployed daily. The idea of an IP-based PBX is useful. Firstly, this system integrates the corporate telephone system with the corporate computer network, removing the need for two separate networks. A new office is wired for voice communication, as well. The PBX itself becomes just another server or group of servers in the corporate LAN, which helps to facilitate voice/data integration. We would be implementing a soft PBX that is going to be a server that performs call-routing functions, replacing the traditional legacy PBX or key system. Our PBX would allow a number of attached soft phones to make calls to one another and to connect to other telephone services. The basic software would include many features available in proprietary PBX systems: voice mail, conference calling, interactive voice response, and automatic call distribution, just to name a few. Our system would also help the user in building the dial plan for the network. We would be using the Session Initiation Protocol as our VoIP protocol. Our PBX would be acting as both the registrar and as a gateway between the soft phones. 12/9/2010 Page 4 of 41
Purpose of Document The purpose is to completely document all the testing activates carried out by the testing and the development team on the SPBX system. These documents would help the maintenance team to completely track all the testing and Quality assurance activities carried out on the project during the project development life cycle. The document is meant for all the end users including the development team, maintenance team as well as the testing team. The document ensures the client of the software that all the standard quality assurance and testing activates have been done and carried out on the project before handing it over to the client. Scope of Testing The testing process involves the following main parts: i) Examining the system against the functional and non functional requirements provided in the functional specification document. ii) Completely checking the conformance of the system to its requirements and user expectations according to the use cases given in the functional specification document. iii) Executing an implementation of different modules of SPBX with test data and examining the output of the System and its operational behavior that it is performing as required or expected. iv) Different testing techniques have been carried out like Black box testing, white box testing and the acceptance test. 12/9/2010 Page 5 of 41

It involves testing the behavior of the register user functionality of the system by checking all possible outputs with respect to the possible inputs given to it. 12/9/2010 Page 36 of 41
Input Parameters Expected Output Actual Output Test Conformance Status Possible Reason(s) in case of failure For valid inputs Caller id should be 4 digit number. 4567 Output of the system should be successful GUI no 4 will be Successful Validation of the number and display of GUI 4 will be Passed for all inputs For invalid inputs Caller id shouldn t be negative. Output of the system should be successful GUI no 5 will be No Test Case failed!!! -091 123456 @189 13j 12/9/2010 Page 37 of 41
Exit Criteria : No high priority problems are open All functions identified in the requirement document are present and working No input/output error found in all the modules during the testing After testing, all the modules of the system are verified and validated with respect to the requirement specification document. All unit test applied on the modules are passed. The system and all of its modules have clearly passed the acceptance test and it should be handed over to the client.

Services include payload type identification, sequence numbering, time stamping and delivery monitoring. The media gateways that digitize voice use the RTP protocol to deliver the voice (bearer) traffic. The RTP protocol provides features for real-time applications, with the ability to reconstruct timing, loss detection, security, content delivery and identification of encoding schemes. For each participant, a particular pair of destination IP addresses defines the session between the two endpoints, which translate into a single RTP session for each phone call in progress. RTP is an application service built on UDP, so it is connectionless, with best-effort delivery. Although RTP is connectionless, it does have a sequencing system that allows for the detection of missing packets. As part of its specification, the RTP Payload Type field includes the encoding scheme that the media gateway uses to digitize the voice content. This field identifies the RTP payload format and determines its interpretation by the CODEC in the media gateway. 12/9/2010 Page 39 of 41
A profile specifies a default static mapping of payload type codes to payload formats. With the different types of encoding schemes and packet creation rates, RTP packets can vary in size and interval. Administrators must take RTP parameters into account when planning voice services. All the combined parameters of the RTP sessions dictate how much bandwidth is consumed by the voice bearer traffic. RTP traffic that carries voice traffic is the single greatest contributor to the VoIP network load. Session Initiation Protocol (SIP) The Session Initiation Protocol is part of IETF's multimedia data and control protocol framework. SIP is a powerful client-server signaling protocol used in VoIP networks. SIP handles the setup and tears down of multimedia sessions between speakers; these sessions can include multimedia conferences, telephone calls, and multimedia distribution. SIP is a text-based signaling protocol transported over either TCP or UDP, and is designed to be lightweight. It inherited some design philosophy and architecture from the Hypertext Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP) to ensure its simplicity, efficiency and extensibility. SIP uses invitations to create Session Description Protocol (SDP) messages to carry out capability exchange and to setup call control channel use. These invitations allow participants to agree on a set of compatible media types. SIP supports user mobility by proxying and redirecting requests to the user's current location. Users can inform the server of their current location (IP address or URL) by sending a registration message to a registrar. This function is powerful and often needed for a highly mobile voice user base. The SIP client-server application has two modes of operation; SIP clients can ether signal through a proxy or redirect server. 12/9/2010 Page 40 of 41
Using proxy mode, SIP clients send requests to the proxy and the proxy either handles requests or forwards them on to other SIP servers. Jitter Jitter is the measure of time between when a packet is expected to arrive to when it actually arrives. In other words, with a constant packet transmission rate of every 20 ms, every packet would be expected to arrive at the destination exactly every 20 ms. The greatest culprit of jitter is queuing variations caused by dynamic changes in network traffic loads. Another cause is packets that might sometimes take a different equal-cost link that is not physically (or electrically) the same length as the other links. Media gateways have play-out buffers that buffer a packet stream, so that the reconstructed voice waveform is not affected by packet jitter. Play-out buffers can minimize the effects of jitter, but cannot eliminate severe jitter. Although some amount of jitter is to be expected, severe jitter can cause voice quality issues because the media gateway might discard packets arriving out of order. In this condition, the media gateway could starve its play-out buffer and cause gaps in the reconstructed waveform. G.729 Codec G.729 is an audio data compression algorithm for voice that compresses voice audio in chunks of 10 milliseconds. G.729 is mostly used in Voice over IP (VoIP) applications like SIP phones for its low bandwidth requirement. Standard G.729 operates at 8 kbit/s, but there are extensions, which provide also 6.4 kbit/s and 11.8 kbit/s rates for marginally worse and better speech quality respectively. It also requires less computation during encoding and decoding. 12/9/2010 Page 41 of 41
