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”

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.

Evolving to Converged communication with SIP (Avaya)hot!

11.05.2005

Organizations with multi-vendor, multi-application and widely distributed communications systems need a reliable way to integrate and optimize their network infrastructure. Session Initiation Protocol (SIP) supports converged communication applications by placing control of the communication across distributed networked entities and smoothly integrating the various system levels. SIP enables seamless data and voice convergence in multi-vendor environments with multiple applications across a wide range of industry sectors.

This white paper is designed to help business leaders understand the impact of SIP-based converged communication in Voice over IP (VoIP), Unified Communication and Customer Relationship Management (CRM) solutions. This paper also offers CIOs guidelines for migration to an enterprise SIP network, and details some new Converged Communication Solutions.

Enterprising with SIP - A Technology Overview (Avaya)hot!

02.02.2004

The vision that Avaya has for converged voice and data communications is to create a network environment that supports maximum enterprise efficiency. Session Initiation Protocol (SIP) [18] is a key technology for this evolution towards a converged communication architecture. SIP as an enabler of converged communication applications has been able to gain industry-wide acceptance by placing control of the communication across distributed networked entities and by providing a means of integration at various levels in the protocol stack. Such integration is now possible in a multi-vendor environment with multiple applications across a wide range of industry sectors. Converged communications that is driven by ubiquitous IP network connectivity defines the next stage of evolution in enterprise communications.

SIP is an application layer, peer-to-peer communication protocol that facilitates openness, simplicity, flexibility, and reuse in an "All IP" Architecture. This paper offers a look at how Avaya views SIP in enterprise evolution. It also describes SIP technology, elaborates on the role of SIP in realizing converged communications, and describes details of the SIP protocol and associated technologies.
