New Cisco Voice-over-IP (VoIP) Section on!

Written by Administrator. Posted in Site News

VoIP articles are finally a reality on!

This new -and long awaited- section aims to cover the VoIP gap in's material and will cover from  basic VoIP concepts to advanced and complicated configuration scenarios using leading VoIP technologies such as Cisco's CallManager Express (CME) and  Cisco's Small Medium Business solutions such as the Cisco UC520, UC540 & UC560 series.

The New Cisco VoIP section aims to provide a solid VOIP configuration reference guide to the VoIP community.

We are extremely excited about this new section as we feel it is essential to provide a broader and more complete coverage of network technologies to our global community.

The new VoIP section kick-starts with the Introduction of Cisco CallManager Express. Concepts and  configuration guides covered also apply to Cisco's popular SMB UC520, UC540 & UC560 series VoIP PBXs.

The introduction article analyses CallManager Express, what it runs on, what IOS software releases support it and how routers are transformed into fully-capable VoIP PBX's. In addition, you'll find information on voice interfaces commonly found on Cisco routers, how important they are and how they are used to connect to the  public switching telephony network.

Our Basic VoIP Concepts article illustrates how Cisco's CallManager Express and UC500, UC520 & UC540 systems work along with Cisco network switches and Cisco IP Phones. Voice Vlans are also covered in order to explain how important their existence is within an VoIP network.

We also take a look at basic telephone configuration on Cisco's Call Manager Express by explaining the 'ephone' and 'ephone-dn' concepts, how extensions are assigned to Cisco IP Phones.

Closing, VoIP codecs are also explained (G.711 & G729), which are used frequently on CME systems and why.

Of course, all the above are covered using our popular illustrated diagrams, presented in a simple manner to ensure our material is easily understood.

To read the first VoIP article (three pages), simply follow the link  below:

Introduction to Cisco CallManager Express (CME)

All Future VoIP articles covering CallManager Express, UC500, UC520 & UC540 PBXs will be located in the  'Technical KnowledgeBase > Cisco VoIP Technologies' Section of our menu.
