Quick Overview

Day 1 is optional for students who are less familiar with IP and SIP networking.

In other words, look at the outline for the SIP course and if the students are not knowledgeable of the key concepts, then Day 1 is recommended.

Day 2 & 3 is the indepth SIP course.

NOTE: All content can be re-organized or customized to suit specific learning needs. Call to discuss.

NEW for 2014 – Designing and Planning Scalable SIP Networks

The five areas of discussion presented (with modifications I added) are:

Here are the highlights in text format:

1 – Benefits of Server Virtualization aka Abstraction

– Distributed user endpoints and application servers

– Scalable growth with QoS control abstraction

– MACS* via signaling “abstraction”

*Moves, Adds, Changes & SAS-Stand Alone Survivability – SAS enables backup for SIP devices by the multiple “abstract” local or cloud Media Gateway(s)

2 – Benefits of SIP Trunking

– Session and Signaling control layers for:

– On-net (IP PBX to IP PBX)

– Off-net (IP PBX to local PSTN)

– Off-net (IP PBX to LD/IDDD PSTN)

– SPOC/SMOC-Single/Multiple Point of Connection

– National control points for access (vendors) – Migration path to ALL-SIP & IMS-3GPP

3 – Benefits of Number Transparency

– End-to-end media control (transparency) for voice or other media types

– Access to SS7 applications for text messaging, mobility or call center routing

– Enterprise control over call completion whether PSTN or SIP rather than provider

– Migration path to E.164 & IMS-3GPP

4 – Benefits of SIP Routing

– Eliminates “mesh” network mess

– Add intelligent Session Layer 5 routing – Maintains end-to-end media transparency

– Add media CoS-Classes of Service – Adds SPOC NOC-Network Operations Center

– Migration path to ALL-SIP & IMS-3GPP

5 – Benefits of SIP Proxy Peering Networks

– Platform for multi-vendor services

– Ensures multiple CoS & QoS options

– Migration path to ALL-SIP & IMS-3GPP

– Foundation for any future network needs

– UDDI-Universal Description, Discovery and Integration uses standards-based services such as XML, HTTP, SOAP, TCP/IP (define above) uniform service description and service discovery protocol. Discovery services provide a consistent publishing interface and allow programmatic discovery (registration) of services. Description services provide the means for internet registration – to be found but not advertisement or placement on search engine listings. UDDI file structures are designed using a “publish-once-read-by-many” concept. That is, web site URL-Uniform Resource Locator can be designed using UDDI standard file structures which can be published to the UDDI server network. The UDDI network can be accessed (discovered) by search engines, customers and other list builders in a standard published (register) format. UDDI Registries and protocol servers with:

– White Pages – Names, Address, Contact and Vcard information

– Yellow Pages – Industry categorizations and taxonomies

– Green Pages – Technical information including internal URL file discovery structures

– UDDI is also designed to replace the robot.txt search engine web site document structure concept. Here are some of the web site description-discovery-registry information retrieved by search engine spiders/bots and other retrieval programs.

– Voice-driven yellow pages – SALT-Speech Applications Language Tags adds voice commands to web applications. SALT is an extended set of markup (meta) tags based on XML-eXtensible Markup Language though compatible with HTML-Hyper-Text Markup Language and others.
