I hear often that it is hard to practice/demo voice related configurations with GNS3. This is only partially true.
It is correct that GNS3 cannot substitute Multiservice routers like 28xx etc because the DSP resources cannot be emulated. For using T1/E1 or FXS/FXO connections you need the real hardware interfaces and of course another PBX/router interface to connect your T1 to. If you have a double T1 you could use a T1 x-over to let the router do both ends.
For all other configurations like Dial-peers, translation patterns, SIP-UA configurations, CME, ephone registrations, CUBE etc, GNS3 can do the job. Just an example…
I have often been asked for a quick way to convert a Cisco IP-Phone between SIP and SCCP. People get their IP-Phones often from E-Bay or other 2nd hand resource for testing and practicing and they may receive them with the ”other” phone load they didn’t want. The easiest way to convert is via Autoregistration. With CME this is a litle more complex, but with UCM (v6 or higher) this is an easy task.
First of all, switch on Autoregistration. If you need help with that, there is another post by Brandon in this blog how to switch on Autoregistration.

I want to take a minute to address the over 450 subscribers here at GlobalConfig.net. Over a year ago when I started blogging I was primarily about my CCIE Studies. Now that I have passed the CCIE Security I am on to the R&S and Voice, kinda at the same time. With that, work, and family it’s been difficult to bring you fresh, useful content. That’s all about to change.
Here are the changes to the blog that I believe will make it a better resource for you:

The amount of detail [Doug] put into his Dr. Frankenstein MAME cabinet is outrageous! Usually we’re more interested in the guts, but in this case the real story is the cabinet itself. Painted to resemble weathered metal, the effect of dripping water is visible on every rivet. There are illuminated portals on either side: one shows the monster, the other shows the bride and the good doctor. Sprinkled throughout the case are analog dials, lamps, and other laboratory bits. [Doug] tops off the design by concealing the power switch inside a book of Frankenstein’s lab notes which is tucked…
[Viktor's] laptop needed a new battery; he had the trade off between carrying around a cheap but heavy sealed lead acid (SLA) battery, or buying an expensive but light Li-Ion battery. Figuring his old laptop was pretty heavy already, and having an unused SLA available, re-purposing it for his laptop wouldn’t be too much of a hassle. Using a boost converter he built out of a custom dip MAX668, he is able to output the necessary 5 amps required. An MC 34161 voltage monitor chip is planned for future revisions, but he’s currently running it just fine. Check out…

Hard drive speakers aren’t anything new, but they have yet to be done very professionally. Most hard drive speaker hacks are awesome, but aren’t meant to be a showpiece. [Oliver] took the opportunity to put together a set of 20GB drives and a custom-built acrylic case with a horizontal VU meter up front. The project is well-photographed and documented and can be recreated without the use of laser cutters or other expensive tools. The only thing it’s missing is an iPod dock!

Author : jigneshChicago’s Corus Bank, which made a disastrous bet on condo towers in South Florida, was closed by federal regulators on Friday. MB Financial Bank of Chicago is assuming Corus Bank’s 11 branches and $3 billion in cash and marketable securities. That would leave about $4 billion more in assets, which the FDIC plans to sell within 30 days in a private placement. Corus has about $1 billion of loans in South Florida. There has been speculation that Miami Dolphins owner Stephen M. Ross might be interested in acquiring the Corus property. Ross is CEO of New York real…
With CUCM you can auto-register phones provided a simple configuration is in place. While this is not rocket science it’s nice to have the walkthrough to look back on so here it goes.
Ensure that the Cisco CallManager service is enabled by going to Cisco Unified Serviceability then select Tools>Service Activation and ensure that the Call Manager Service is enabled.
Uploaded with plasq’s Skitch!
Next go to Cisco Unified CM Administration and select System>Cisco Unified CM
Once there you should notice that the default configuration has auto-registration disabled.

While auto-registration is disabled the phone will cycle…
[Sebastian Tomczak] was borrowing a homeade muon detector from his friend, and managed to hook it up to his computer through an Arduino. The detector itself uses 3 fluorescent tubes to detect radiation. Three separate tubes are used in order to filter out terrestrial radiation; cosmic radiation will fall in-line with the tubes and pass through at least two of them, whereas terrestrial radiation will only hit one. There is some basic circuitry to amplify the signal and then perform the OR operation.
[Tomczak] used an Arduino to take the raw data and feed it into his computer. He…
