A Perspective on Cisco – Microsoft Interop

Hi there,

I happen to present a perspective on Cisco and Microsoft UC interop at MS Lync User group in Singapore. The presentation is around mostly the business and economies of scale when doing Cisco + MS however, for all you technical audience the good news is yes – it has a lot to offer from a technical stand point. Examples of Cisco UC with Lync interop from Voice and Video are covered. See for yourself and download the presentation.

Cisco Live Session on CUCM based SIP URI and ILS

Join me for an informative presentation hosted by Cisco Live on 16 Sep 2014 at 10:00 a.m. PDT / 1:00 p.m. EDT / 19:00 CEST; on one of the topics from CCIE Collaboration exam. This session is based on CCIE Collaboration written and lab exam topic: CUCM based SIP URI and ILS. For an in-depth insight of this topic and many other topics please read CCIE Collaboration Quick Reference by Cisco Press http://click.linksynergy.com/fs-bin/click?id=aV8WWcTd0Yc&offerid=145238.10000399&type=3&subid=0.

Here’s the session snippet as seen on Cisco Live website:

The session aims at CUCM based SIP Uniform Resource Identifier (URI) dialing and its blend with Intercluster Lookup Service (ILS) alongside blended addressing. The session will help audience relate to the benefits of using URI and ILS in a converged network. Being an important topic for CCIE Collaboration aspirants, this session will provide an insight to planning and configuring URI scheme and implement ILS networking in a CUCM cluster.

CUCM based SIP URI Dialing and ILS Networking

So, here’s an article I wrote for CSC as part of Chalk Talk series. This article walks through the basics of SIP URI dialing and ILS networking as well as touches blended addressing in CUCM. The article is published as part of Cisco’s Technical Services Newsletter, July issue http://www.cisco.com/web/services/technical-services-newsletter/index.html

Here’s the excerpt from the article:


 

Cisco Collaboration solutions offer much more than just traditional ways to communicate within and outside of an enterprise network. Complementing the next generation communication solutions such as SIP gateways, SIP endpoints, Jabber, WebEx etc., Cisco Unified Communications Manager (CUCM) has evolved to a degree that it can work and integrate with multiple platforms and can serve multitude endpoints. This article highlights features and benefits of the recent inclusion – SIP Uniform Resource Identifier (URI) based dialing as well as support for Intercluster Lookup Service (ILS) Networking.

SIP URI Dialing

In context of Cisco Collaboration, SIP URI can be best compared to an email address such as abc@xyz.com. The URI format is usually general form: sip:user:password@host:port;uri-parameters?headers. This format has been used by SIP dominant networks for years and is now gaining universal popularity because of its globally routable (DNS-based) nature/capability. A SIP URI can be automatically imported from LDAP (provided the cluster is integrated with an LDAP server) such as a mail or the msRTCSIP-primaryuseraddress attribute.

Following are salient features of SIP URI:

  • In a SIP URI a user name is optional however, CUCM does not support URIs without a user name
  • URI parameters and headers are optional
  • The user name is case sensitive however host is case insensitive (RFC 3261). This parameter is configurable starting CUCM 9.1 (under Enterprise Parameters – URI lookup policy)

SIP URI and ILS Networking are important concepts from CCIE Collaboration exam perspective. For in depth information about these concepts and how to deploy them in a CUCM intra/inter cluster environment please read CCIE Collaboration Quick Reference

CCIE Collaboration Quick Reference Gets Reviewed

Firewall.cx is a Cisco approved reviewer and they get the first copies out of press (no wonder right)! Firewall.cx was kind enough to review CCIE Collaboration Quick Reference. I’m excited and happy to share the news that the book got 5 / 5 (a full score – a bingo) per Firewall.cx review – which is a testament for the title’s approach to CCIE Collaboration exam.

Here’s an excerpt from the review at http://www.firewall.cx/general-topics-reviews/book-reviews/186-certifications-study-guides/1046-ccie-collaboration-quick-reference-review.html

This ebook has been designed for a specific target audience, as the title of the book suggests, hence it cannot be alleged that it is not suitable for all levels of Cisco expertise. Furthermore, since it is a quick reference, there is no scope for something like poetic licence. As a quick reference, it achieves the two key aims:

1) Provide precise information
2) Do it in a structured format

And eliminate any complexity or ambiguity on the subject matter by adhering to these two key aims.

Readers of this review have to bear in mind that the review is not about the content/subject matter and its technical accuracy. This has already been achieved by the technical reviewer, as mentioned in the formative sections of the ebook. This review is all about how effectively the ebook manages to deliver key information to its users.

To read the full review please visit http://www.firewall.cx/general-topics-reviews/book-reviews/186-certifications-study-guides/1046-ccie-collaboration-quick-reference-review.html

Happy reading!

Chalk Talk – QoS Considerations for Virtualized Cisco Unified Communications

So, I decided to write about a much coveted topic – QoS Considerations for Virtualized Cisco Unified Communications. This article was published in Cisco Technical Services Newsletter of May 2014.

https://supportforums.cisco.com/document/12180866/chalk-talk-qos-considerations-virtualized-cisco-unified-communications

Here’s an excerpt from the article:

Cisco Collaboration (aka Cisco Unified Communications) solutions have come a long way since the conception of IP Telephony. With advancements in technology and the need to reduce economic and environmental impact, virtualization is well on way to become the core of all major technologies including Unified Communications. Cisco Collaboration solutions are now fully supported on Cisco UCS, with backend Nexus, storage, and Fibre Channel over Ethernet (FCoE) based systems complementing the next gen solutions.

However, with inclusion and dependency on virtualized environments the issue of Quality of Service (QoS) remains to be understood as it is no longer physical switches, NICs, or application instances that are deployed; it is virtual switches (for example Nexus 1000V), virtual NICs, and virtual machines that are deployed as Cisco Collaboration solutions are increasingly virtualized.

For full article refer to – https://supportforums.cisco.com/document/12180866/chalk-talk-qos-considerations-virtualized-cisco-unified-communications

Moreover, as a bonus, you can get 35% off on CCIE Collaboration Quick Reference eBook. See the article for more details!
