The book on IP communications, which is created especially to help network administrator in the development of voice and IP telephony technologies, plan and develop solutions for converged networks. The book provides guidance on planning, evaluating and implementing solutions based on SIP. Most large enterprises have switched or switched to IP telephony, the networks of the vast majority of operators and service providers have implemented IP telephony. But still, there are operators and enterprises that still use connections based on old and poorly scalable TDM trunks.
The authors of the book start the book with the explanation sip trunking for dummies and demonstrate how using SIP connections you can get all the benefits of VoIP solutions. The book is addressed to decision-makers at enterprises: network architects, consultants, technical operators and service providers, the book reveals trunking technologies and SIP trends and brings clarity in the transition process from TDM to VoIP technologies. The authors of the book share the real benefits of SIP and reveal the popular myths, thus helping to systematically evaluate and compare providers’ offers. The book provides a detailed cost analysis, as well as real and achievable ways to reduce costs. The book describes the main techniques and methods for optimizing projected networks and security, advanced and proven techniques, shows how to apply them from beginning to end.

The first chapter of the book is dedicated to the history of IP telephony, the basic components of an IP-based telephone network ranging from microphones and digital signal processors (DSP) to voice gateways and IP PBXs. The existing signaling protocols are compared. The second part discusses trends in IP telephony – SIP trunking for enterprises and service providers and contact centers. In the third part, we will talk about the transition to SIP trunking: assessment of the current state, definition of priority tasks, peculiarities of transition to SIP Contact Centers, head offices, branches. In the fourth part, the costs for installation, equipment, the cost of ownership and security are analyzed. The fifth part describes the components of the service provider network:
IP infrastructure, Session Border Controllers, Customer Premise Equipment, media gateways (voice and video), billing, monitoring, application servers and description of enterprise network components. In the sixth part, the SIP trunking models are discussed: centralized, distributed and hybrid models. In the seventh part, considerations are given to the design and implementation of the SIP trunking model, taking into account various factors.
The eighth part deals with interworking of protocols, codecs, faxing, applications, terminals, etc.
In the ninth part, it is proposed to consider the issues that SBC vendor should be asked before choosing a particular solution: for example, technical requirements, support model, SIP features, SIP methods, IETF recommendations, QoS, security, firewall integration, access control, management Security, availability, load balancing, redundancy, availability of certificates, documentation … a complete list of questions in the book. In the tenth part, scenarios of deployment of SIP trunking are presented or it is better to say networks where SIP trunking is used:
- Cisco Unified Communications Manager SIP trunks;
- Cisco Unified Communications Manager H323 connection;
- Separation of SIP Trunks at the enterprise level;
- Connection of Contact Centers using SIP trunk;
- SIP trunks for small businesses for connection to the PSTN network as well as additional options for deploying SIP trunks.
The eleventh chapter discusses the steps and best practices for deploying SIP tracing. In the twelfth chapter, various teaching examples are given.
