SIP: providers, schools, information, questions and answers

Companies switching to VoIP should consider the SIP standard as it makes them vendor-independent. No All-IP strategy today can do without this protocol, as it does so much more than just signaling voice. With Session Initiation Protocol telephones, collaboration with other applications and systems is possible. It is also possible to connect directly to a Session Initiation Protocol provider via a cable line, which then ensures maintenance, availability and support. This is a particular advantage for smaller companies. If they have written off their telephony infrastructure (IDSN solution), they should consider SIP as the VoIP standard when making a new purchase. SIP telephones are compatible with many systems or solutions. This is important if the communication solution is to work with or be integrated into other systems. It is important to check the functions against your own requirements in advance.

A SIP course provides knowledge about the introduction, motivation, philosophy, basics and operating rules of the SIP protocol. It explains how to implement telecommunication services with a focus on IP telephony and VoIP. A training course may cover the following topics:

• Introduction of telephony via IP networks
• The SIP Proxy, Location Server and User Agent components
• Functionalities
• Back-to-Back User Agent (B2BUA) and Session Border Controller (SBC)
• The protocol, its message types and their structure
• Scalability and redundancy options
• Typical processes in the course of establishing a connection and during a call
• URIs and Tel-URIs: Address formats, identities and their use
• SDP: Structure, possibilities and profiles
• Data streams for VoIP and video over IP (RTP and signaling)
• Features - Instant messaging - Presence
• Value-added services in the SIP environment: unified communications, conference applications
• in interaction with NAT and firewalls
• Fax with T.38 and the connection with Session Initiation Protocol
• as a protocol in the IP Multimedia Subsystem (IMS)
• Use of Session Initiation Protocol in provider networks
• SIP trunking - replacement of the exchange line header

The SIP courses are aimed at employees who are involved with this standard at a planning, conceptual or protocol level. In most cases, a sound knowledge of VoIP is required to take part in the course. Graduates know the advantages, special features and possible applications of the SIP architecture in general and trunking in particular.
