Ingate Systems: SIP Trunking Benefits and Best Practices hot!
- 19.06.2007
- SIP Trunking Benefits and Best Practices By Janne Magnusson, Vice President, Product Management Ingate® Systems A complete guide to SIP trunks, this whitepaper provides a comprehensive overview on the basics of SIP trunking, including a discussion of infrastructure needs and deployment issues and solutions. In-depth sections dedicated to interoperability, security and quality and reliability issues are also included. Editorials from ShoreTel, Level 3, Cbeyond/SIP Connect and Ingate provide a unique look at the perspectives from the IP-PBX, ITSP and other thought leader points-of-view. SIP trunks can lower telephony costs and deliver rapid return on investment (ROI). They also offer the opportunity for enhanced communications both within the enterprise and with vendors, customers and partners. While some see SIP as just voice, SIP trunking can also serve as the starting point for the entire breadth of realtime communications possible with the protocol, including Instant Messaging, presence applications, whiteboarding and application sharing. Adding their unique insights to the white paper are editorials by: - ShoreTel, Inc. – “Developing a Working Solution End-to-End” - Level 3 – “A Service Provider’s Perspective on SIP Trunking” - Ingate Systems – “Who Is Listening to My Calls?” - Cbeyond – “SIP Connect: An Industry Collaboration Success Story”

Solving the Firewall/NAT Traversal Issue of SIP: Who Should Control Your Security Infrastructure?hot!
- 17.05.2007
- Solving the Firewall/NAT Traversal Issue of SIP: Who Should Control Your Security Infrastructure? Session Initiation Protocol (SIP) has become the signaling protocol of choice for realtime communications, including Voice over IP (VoIP){mosimage}. However, SIP communication does not reach users on the local area network (LAN) behind firewalls and Network Address Translation (NAT) routers automatically. This issue of SIP traffic not traversing the enterprise firewall or NAT is critical to any SIP implementation, including VoIP. Until all firewalls are SIP capable in order to support the wide-scale deployment of realtime enterprise communications, several solutions have been proposed to work around the firewall/NAT traversal problem. Many of these solutions have serious security implications; there are also solutions that allow you to remain in control. The choice of method for traversing firewalls/NATs is, to a large extent, dependent on the answer to the questions: “Who should be in control of your security infrastructure: the firewall administrator, the user or a service provider?” and, “Do we want a solution that is predictable and functions reliably with SIP standard compliant equipment or is it sufficient with a best effort solution that works in certain scenarios and, perhaps, only with a specific operator?” This white paper outlines the pros and cons of each solution, so you can make the best decision for your network.

Genesys IP Media eXchange Testing Reporthot!
- 11.09.2006
- CT Labs was commissioned by Genesys to evaluate the call-handling performance of the IP Media eXchange (IPMX). The IPMX compo-nents were deployed on one, two, and three Windows-based servers, respectively, for each of the three tests described in this report. All VoIP calls were generated using an automation script running on the Empirix Hammer FX-IP platform, using the SIP protocol. In the first test, the IPMX was deployed on a single server. The results of this test reveal that a single high-performance server with 150 agents configured can effectively process in excess of 250 simultaneous callers at a rate of 8 calls/second, with half listening to music on hold, and the other half connected to agents.

Navigating the Complexities of IMS (Empirix)hot!
- 07.09.2006
- IP Multimedia Subsystem (IMS) is moving the communications industry towards a new business model. No longer are proprietary solutions with long development cycles and network-centric applications the solution for the network equipment manufacturer or service provider community to enable feature-rich services. Traditionally, end user, network, testing/monitoring, and maintenance applications have been dictated by the access and network infrastructure equipment capabilities and feature sets. These applications have been integrated into the legacy equipment and the ability to customize has been extremely limited. However, these applications due to their proprietary and static nature and long development timeframes are very reliable and provide a high quality end user experience. This quality and reliability needs to be duplicated in the IMS environment and applied to real-time, next-generation applications but in a much quicker timeframe across diverse networks and devices.

Testing SIP to Saturation (UNH-IOL)hot!
- 07.09.2006
- The SIP (session initiation protocol) signaling protocol is emerging as the industry’s preferred Voice over IP (VoIP) technology. As such, SIP’s scalability is key to VoIP technology’s continued adoption, and the need to test SIP user agents and servers under heavily saturated scenarios is becoming more acute. SIP servers must be able to bear heavy traffic loads for user registration and call setup functions that require reading from and writing to one or more large dynamic database(s). The corresponding test tools, call generators, terminators and analyzers must all be capable of processing the same significant loads. The University of New Hampshire InterOperability Laboratory (UNH-IOL) can test a large variety of VoIP and traditional telephony systems; however the focus of this paper is not to demonstrate the comparative performance of individual SIP servers, but rather to delineate issues involved in testing SIP servers under heavy call saturation.

QoS Testing in the VoIP Environment (Empirix)hot!
- 14.03.2006
-
In recent years, the business world has reaped tremendous benefits from the many exciting products and applications made possible by the marriage of data and voice technologies. Now, the efficiencies and enhanced services resulting from that revolution are being enhanced by the magnitude of change possible as data networks become the transport for voice. IP Telephony, or Voice over IP (VoIP), is the exploding new technology enabling voice to be carried over IP-based, packet-switched local and wide area networks.
Now the efficiencies and enhanced services resulting from that revolution are being eclipsed by the magnitude of change possible as data networks become the transport for voice. The open standards approach adopted within the voice over IP world has meant that public and private network operators are now able to remove their dependence on buying everything from one vendor that was a fact of life in the closed/proprietary nature of the traditional circuit- switched world. Other advantages that have attracted a lot of attention include the ability to bypass the PSTN and its toll charges,applications made possible by merging voice with Internet data,lower operating expenses,and network service presence.

Person-to-person realtime IP communications, like presence, VoIP and video applications, offer clear benefits for the enterprise as time- and money-savers. Unified functionality is now available, where all of the above are integrated into one streamlined application and interconnect with other networks. This creates a very important business tool and usage is increasing.
Session Initiation Protocol (SIP) has emerged as the protocol that will fuel this development. Its simplicity and the fact that it is based on Internet standards give SIP clear advantages over older protocols. Analysts predict that SIP will dominate and the evidence given by actual deployments among service providers and equipment vendors further support that prediction.
This white paper describes the security issues associated with SIP, and how to address them within enterprise domains.

Support for Session Initiation Protocol, or SIP, is essential in today_Ts enterprise communications environment. With the standardization of SIP as the Internet protocol for applications such as VoIP, instant messaging and IP telephony, businesses are eager to adapt their existing hardware to accept SIP. However, far too many companies have made substantial investments into legacy firewall technologies that are not capable of supporting this type of communication. In addition, enterprises are reluctant to touch existing security infrastructure for fear of creating security breaches.
The award-winning Ingate SIParator® addresses these issues by offering the introduction of a SIP-capable communications infrastructure while preserving the investment made in legacy firewalls.
