Trinity SIP Tester call generator. Star. Trinity SIP Tester is a Vo. IP load testing tool which enables you to test and monitor Vo. IP network, SIP software or hardware. It is able to simulate and passively monitor thousands of simultaneous incoming and outgoing SIP calls with RTP media, analyze call quality and build real time reports. Call flow is specified by Call.

The SIP Tester runs on any Windows PC without special hardware and simulates application server, media server, SIP phone or register server. Freeware license of SIP tester allows 5. For extended number of calls commercial license is available. The software is licensed and protected by law see license agreement for details. The unlimited license for the SIP Tester is free for medical organizations hospitals, research institutes, charity, and nature protection organizations. Most of customers test their SIP software, servers and network, and we dont know details. Here are details of using SIP Tester which have been shared to us. Wavefront was recently commissioned to loadtest a client IVR platform and started researching tools that could provide SIP load with media support. I was reluctant to use a Windows based product since I knew I would have to integrate with a Linux based custom load generator for SMS along with a reporting tool. We came across SIPTester and quickly became comfortable with scripting in the Call. XML language for creating complex inbound and outbound call scenarios. The SIPTester code is very efficient with a small memoryCPU footprint. Personally I never experienced a single crash, which was my biggest concern using a Windows based loadtest tool. Using the SIPTester command line mode and returned exit codes, we were able to integrate testing across platforms and tie in reporting tools using Windows batch scripts. The bulk of my previous SIP load testing experience was with SIPp for Linux. Fortunately the open source SIPp project does not support media very well and I was forced to look for another tool. It was fortunate because if SIPp had supported media I may not have discovered SIPTester. We never came close to the limit of complexity of interactions that can be scripted with SIPTester. For example, SIPTester can listen to inbound media, compare the received audio with reference files and branch accordingly. This means two way conversations can be achieved very easily and the Call. XML scripting language makes using these types of RTP aware features very intuitive. I experimented with these features but their use was out of scope of our project. The list of features supported by SIPTester is very impressive but equally impressive is the comprehensive documentation available for each feature and the including examples. The documentation is freely available to study on the developers website and is constantly growing and improving as features are added. Our team found development of SIPTester Call. XML scripts very easy. The tool itself is like an IDE in that it does real time syntax checking, and call scenarios can be created via GUI or directly via Call. XML scripts. The tool has detailed performance reporting based not just on signalling but also on RTP metrics such as levels, jitter and loss. The tool also support WAN emulation such as impairment generation arbitrary packet loss etc. The value for such a powerful and mature SIP loadtest platform is extremely good and the way SIPTester can be evaluated in demo mode before purchasing, with all functionality enabled, makes it a risk free investment. The developer team at Star. Trinity is very responsive to support and feature requests. I found the developers to be very knowledgably, professional and pleasant to work with. I look forward to working with the Star. Trinity team and products in the future and have been recommending the SIPTester product whenever appropriate. Greg Toews, P. Eng. Manager, Engineering. Wavefront. Vancouver BCCanada. Customer5. 1 in North America used SIP Tester to run Vo. Battlefield Bad Company 2 Demo Chip here. IP tests in a satellite IP network. They have been facing some voice quality issues in the network and their vendor was unable to find solutions. With SIP Tester customer5. Huawei IP Phones, Voice Core SBC, Softswitch, Media Gateway, LAN switches etc. They aligned the teams and reviewed the procedures and best actions for a more effective analysis, diagnosis and troubleshooting. They used SIP Tester for the call tests using the satellite environment RTT around 6. RFC3. 26. 1 T1 timer and RTP TX packet size to have a better picture of performance. SIP Tester was installed on multiple laptops and servers in both active and passive modes. For passive mode server with SIP Tester was connected to mirror port and collected performance of the live traffic. The customer was happy with quick support and releasing new versions to support their specific configurations. Based on measurements of SIP Tester, also with help of wireshark, customer discovered that. Additionally, received RTP traffic sometimes started around 7. RTP delay. Conclusion was to review the configuration of the central site equipment to improve the voice quality and the total delay. For some calls SIP Tester discovered incorrect audio codec, it was solved with configuration of SIP phones. The worst SIP phones with high packet loss have been identified. Customer addressed every site to mitigate this problem. Overall traffic RFC3. Cases with high jitter impacted by the worst sites. The actions have been being taken to correct 3. Additionally, packet loss was detected from the Huawei Core. The client verified Huawei LAN Switches, and discovered that. Base. T, all interfaces were in half duplex. They requested Huawei to replace the LAN switches with better equipment to operate at 1. Base. T and 0 packet loss, full duplex. Customer was pleased with realtime reports generated by SIP Tester This kind of reports are not available in tools like Wireshark and Pilot. You must go step by step and take a lot of time to analyze and generate some statistical data. Your tool is allowing to create real time datagraphs that will help to speed up the data collection, data analysis, diagnostic, troubleshooting, and optimization. Customer2. SIP Tester to simulate calls from Europe to few remote locations in Caribbean region. The calls were made through customers softswitches, gateways and PSTN network between 2 instances of SIP Tester installed on both ends. Housing Programs For Teachers In Md. How To Become A Solar Power Installer. SIP Tester was configured with custom Call. XML scripts to access list of numbers from CSV file or MSSQL database, generate SIP call, make random delays. CSV CDR files with custom format. Customer4. 4 in North America used SIP Tester to test their Vo. IP recorder. SIP Tester was installed on 2 servers, connected via network switch. Customers Vo. IP recorded was connected to mirroring port and stressed with SIP and RTP traffic generated between 2 instances of SIP Tester. SIP Tester simulated 2. G. 7. 11 SIP calls on i. Custom Call. XML scripts were used to simulate non standard SIP behaviour like call transfers REFER and call parking re INVITE. Before SIP Tester customer did not have enough information about bottlenecks and load capacity of their software. They tried to simulate high call load with Freeswitch, but it crashed. After SIP Tester customer optimized his code to achieve better performance. Additionaly, they discovered that with 4. SIP and RTP packets become lost.
