Normalization scripting for SIP Trunking first step

jderidde — Thu, 10 May 2012 20:03:37 +0000

SIP trunks can connect to a variety of endpoints, including PBXs, gateways, and service providers. Each of these endpoints implements the SIP protocol a bit differently, causing a unique set of interoperability issues. To normalize messages per trunk, Cisco Unified Communications Manager allows you to add or update scripts to the system and then associate them with one or more SIP trunks.

The normalization scripts that you create allow you to preserve, remove, or change the contents of any SIP headers or content bodies, known or unknown. After you configure a normalization script in Cisco Unified Communications Manager, you associate the script with a SIP trunk by configuring the Normalization Script fields in the Trunk Configuration window

The language used is Lua it is an open source, lightweight scripting language.

For info on Lua see http://www.lua.org/

As a practical example we change in the SIP invite for a outgoing call on a sip trunk, the IP destination addresses in the SIP URI to a domain name.

From:

INVITE sip:+3227784342@1.1.1.10:5060 SIP/2.0

The normalization script:

M = {}

function M.outbound_INVITE(msg)

local method, ruri, ver = msg:getRequestLine()

local uri = string.gsub (ruri, “1.1.1.10″, “domain1.a.be”)

msg:setRequestUri(uri)

end

return M

Changes into:

INVITE sip:+3227784200@domain1.a.be:5060 SIP/2.0

Some very good thoughts about Why should you care about Cisco UCS

Michael Neefs — Mon, 19 Mar 2012 20:31:39 +0000

Folks,

I wanted to share a few very good articles and web documents coming from friends into one condensed updated post about all the great things that Cisco UCS can provide to your organization :

Last performances update about our solution :

In the three years since its introduction, Cisco Unified Computing System™ (Cisco UCS™) powered by Intel^® Xeon^® processors captured 63 world performance records,UCS and Intel Xeon Processors: so, please check this out : 63 World-Record Performance Results

In response to what skeptics were saying 3 years ago :

Cisco as a server vendor! Ha!

Remember back when the company first unveiled its “Unified Computing System” (UCS)? At the time, the thought of Cisco being in the server market seemed almost laughable. But, this was a journey that we had seen before. Similar guffawing was heard when Cisco jumped into the voice market. Way back in the day, when I was in internal IT, Cisco acquired its way into the VoIP market and rode the IP wave to market leadership in only about a decade. When you think about how, historically, extremely difficult voice share was to gain, the fact that Cisco managed to grab as much share as it did, and as fast as it did, was remarkable…

Cyber Threat Defense - enhanced visibility into stealthy, advanced network threats

savgoust — Sat, 17 Mar 2012 11:52:34 +0000

Reblogged from Security Down Under:

Advanced Persistent Threats

For many years the security community has been advocating that perimeter defense is just one (although important) part of an overal security architecture. With the threat landscape evolving, both governments and large enterprises became victims of well targeted, custom attacks referred to by the media as Advanced Persistent Threats (APTs).

APTs are often in the form of determined, motivated and possibly well financed attackers who are able to bypass the perimeter defenses of an organization to gain an operational footprint on the network.

Cisco Catalyst 6500 ready to serve you another decade!

Xavier Mertens — Thu, 12 Jan 2012 23:15:22 +0000

The Cisco Catalyst 6500 was born more than 12 years ago when it started its baby steps in the networking market around June 1999. In the last dozen years this platform has seen great evolutions and even caused some ‘revolutions’ in the networking industry. The first release went out and stayed in the market for about 6 years. Then the E-series chassis and SUP720 were introduced as from 2004. One year later in 2005 the SUP32 was also introduced, focusing on the Access layer. Although new chassis were launched you could still use the older chassis for the new SUP720 and SUP32. Also existing linecards could be reused with the new supervisor and in the new chassis. During its lifetime, the platform had some linecard additions, linecard revisions and supervisor enhancements. But overall the solution with SUP720 and SUP32 remained there for another 6 years.

This track record brings us twelve years later in 2012 where a lot of questions from customers arise around the future life of the Catalyst 6500. Certainly after the launch of our Datacenter centric Nexus products most of our customers started to question its future. Can the Catalyst 6500 keep up with these developments? Will the Nexus 7000 replace the Catalyst completely? Or will Cisco launch a complete new platform for the Campus?

Well, exactly at that time the next step for the Catalyst 6500 was already getting ready of being launched. A brand new Supervisor with amazing speed and without compromising on the vast amount of available features on the platform, together with a new set of linecards. The supervisor almost delivers 3x more speed and brings new in-hardware features.

Just to tease you already, it offers an amazing 2 Terabit crossbar with 80 Gbps per slot (even for the 13 slot 6513-E) and also new PFC4 and MSFC5 daughtercard on board. These 3 new components together deliver also new features like TrustSec incl MacSec, VPLS in hardware, L2/L3 MPLS in hardware and innovations in QoS, Managebility and Virtualization. And if these where not yet enough it also offers you up to 512k/1024k (for XL) of Flexible Netflow entries, up to 720Mpps* of IPv4 routing and 390Mpps* of IPv6 routing all performed in hardware as well. Like all the above was not yet enough you can of course use this in a proven Virtual Switching System (VSS) solution offering a massive 4Tbps system with all these features.

As for backward compatibility, the product has been developed with our customers as prior focus, to offer them maximum investment protection on their existing installed base. To begin with, all the existing E-chassis and power supplies are supported with this new hardware. With regards to linecards there are a few options. First of all it supports most of the existing 67xx linecards in CFC or in DFC as soon as you upgrade them to DFC4 with exception for the WS-X6708-10GE linecard which has been replaced with a new WS-X6908-10GE card. These 67xx linecards offer you the same backplane connection of 40Gbps. In case you would be ordering new linecards in this range they are available as a 68xx series where the same hardware ships with the DFC4 upgrade onboard. If you really want to take all advantages of the additional speed you can use the 69xx series linecards which offer you a 80Gbps bandwidth to the backplane. Last but not least it also supports a few of the 61xx line cards but only in a non-VSS setup.

All these new and exciting speeds and features make the Catalyst 6500 ready for again another decade. The platform provides a unique investment protection to customers, valuing the trust they have for all those years already in this great platform. This launch is only a beginning. Don’t forget to visit Cisco Live 2012 in London to discover what this platform will unleash even more in the future.

The Catalyst 6500 serves you again for another decade!

Before and after VXI

Rudy De Keninck — Fri, 23 Dec 2011 21:50:16 +0000

Recent studies have revealed that over 60% of enterprise companies plans to deploy desktop virtualization in some way over the next 3 to 4 years. From a TCO point of view the advantages of desktop virtualization are simply amazing. As we move further into the so called “post-pc era”, having the ability to “port over” the virtual desktop environment to other devices or let’s say locations than the traditional office desk brings unseen flexibility and mobility. Think of our Cius business tablet that offers you a full desktop environment in the office, while keeping access to the virtual desktop over wi-fi or 3G/4G connectivity while on the go.

Desktop virtualization however just doesn’t prove to be that good a solution when it comes to integrating real-time audio and video. Using a soft phone or video client over a display protocol such as Citrix ICA or VMWare PCOIP simply doesn’t scale. “Hair-pinning” all the real-time traffic back and forth to the data center where the virtual desktop resides causes delay and jitter and puts a heavy burden on data center resources, not to mention possible bandwidth exhaustion…

Thanks to our Virtual Expirience Infrastructure or simply VXI, we are able to separate real-time traffic out of the VDI display protocol, routing voice and video traffic directly between end points, bypassing the data center.

Please take a moment to view a short video on our VXI solutions, showing you how separating voice and video traffic from the display protocol enhances the user experience. To start with, you will first see what you get without VXI. They say that seeing is believing. Well, this video really speaks for itself.

To find out more about our VXI offering and VXC clients, please visit the link below, and see how we effectively bring the best of our borderless networking, virtualization and collaboration technologies together.
