Posts from ‘Digit Manipulation’


Austin has devised a dial plan that meets the needs of his company (Backyard Adventures, Inc), and one of the core components of it meets a requirement set forth by his company’s executive branch – namely, that although people in U.S. offices of his company dial a ’9′ as a PSTN access code prior to dialing any additional digits for outside public calls, the executive branch dictates that they do not want the IP phones that dialed such a number to see that preliminary ’9′ on the phone’s display, once the call has been placed.
(e.g. If Pablo dialed 9-206-501-5111 for a local call in Seattle, then his display should only show 2065015111 once the call has been placed)

The Cisco Unified Communications feature called Mobile Connect (also familiarly referred to as Single Number Reach) is truly a great feature of Unified Communications Manager, and can provide us with many efficiencies both in being able to be reachable just about anywhere, and in being able to be easily identified when placing inbound calls from our mobile phones into the CUCM cluster to our colleagues. As admins, we know that if we wish to have our users place calls from their mobile phones inbound to their colleagues inside the CUCM cluster, that we need to match up all or at least part of their inbound calling party number (CLID) to their CUCM Remote Destination. But what happens when what the carrier is sending CLID digits inbound to our IOS voice gateways that differs significantly from our Remote Destinations in CUCM, especially if we have truly embraced Cisco’s push toward true Globalization in v7.0, v8.0 & v8.5?

Just wanted to update all our CCIE Voice rack renters out there that the new Variphy Remote Phone Control app that I blogged about a few days ago will go live here by the next rack rental session at 3pm PT. Information on how to use it can be found in the first few minutes of this video demonstration of the product.

Join me tomorrow, October 22nd at 12:00 PM PST / 3:00 PM EST, for the free vSeminar: Unified Mobility Interactions with Local Route Group and Globalization.

To attend this free vSeminar, use the following URL tomorrow at 12:00 PM PST / 3:00 PM EST: Unified Mobility Interactions with Local Route Group and Globalization

In case you missed any previous vSeminars, be sure to check out the recent updates here.

If you are interested in learning more about technologies covered by the CCIE Voice Lab Exam, check out INE’s Voice Deep Dive. The CCIE Voice Deep Dive is the ideal way to gain in-depth knowledge about specific topics and technologies. We’ve now just completed 17 modules, and unlike other Class on Demand’s that only go to 20 or possibly 25 hours, ours now span over 95 hours of training, and we still have more to go. It truly doesn’t get any “deeper” than this. We will post an update with the complete new table of contents to these 3 newly released Deep Dive modules on CUCME, next week.

Hope to see you tomorrow!

That is a very true saying – in fact one that we believe strongly in here at INE. However we also understand just how expensive it can be to undertake studying for any CCIE Lab exam. That is why, whenever we can, we try to reduce the load on you – the students – to bear this cost. Take for instance our CCIE RS Volume II for Dynamips – we do all we can to provide you the best available instruction while trying to reduce, or sometimes even be able to eliminate the hardware costs associated with studying.

So now we have taken to task trying to do the same for our CCIE Voice track products. We can’t quite virtualize all of the routers used as voice gateways (pesky DSP’s and TDM trunk cards that dynamips won’t ever be able to support since we actually need hardware for the drivers to be able to trigger the signaling), but we thought we would try to reduce the hardware cost for you, the student, in any way we can with the necessary hardware. Anyone having decided to study for the CCIE Voice lab exam has no doubt realized that even if you decide not to take on the enormous cost of building your own rack to practice with, and instead, to rent rack time from any vendor on the market, you still must purchase your own hardware 7961 IP Phones along with some sort of a hardware VPN solution (such as an ASA 5505 or 851 ISR router) at a minimum in order to be able to practice for all of the most important features tested in the lab. This is quite simply due to the fact that the much older 7960′s and all current SCCP Software Client phones (including Cisco CIPC, IPBlue VT-GO*, etc) don’t support any of the newer features – those that are most critical to studying for the latest lab exam. Even if you can manage to find refurbished 7961 IP Phones from eBay for roughly $150/phone and $500/ASA5505 – you still have to invest over $1,000USD just in hardware before you are ready to rent the rack! Seeing as how the 7961 phones are already a generation behind the current ones, and the possibility that when you pass your lab 6-12 months from now that they will likely be 2 generations old and harder to sell for the same price you paid for them – it becomes a very expensive venture to undertake!

We had a great response in turnout to Josh’s vSeminar yesterday. Thanks to everyone who made it out, we certainly hope it was beneficial for you!

A few comments from attendees in the ET helped us realize that the next Voice vSeminar, this Friday covering Simplifying Globalization and Localization, might be best held at 4pET/1pPT, rather than the 6pET/3pPT that it was originally scheduled for. So we changed it.

So why a lecture on this topic? Well, every class that I have taught over the last few months has invariably had most students walking in with a printout of the 40+ page, 3-part series on Globalization, Localization, and Mapping the Global to Local Variant blogs that I posted here on this blog a bit back. They all seem to have the same thing to say: “Excellent post, now can you simplify it just a bit for me and can you also explain why we would want to do any of this?”. So to that end – I decided to take on the task of helping you understand not only how in a much simpler way, but possibly more importantly, the why of it all. Continue Reading

For many of you geeks and nerds out there like me (I’ll take a poll as to which one is better at another time), you’ve worked with some *NIX flavor for many years now. For others of you, you have most likely dabbled with various Linux distro’s and have come to know commands as needed. One extremely powerful tool that you may or may not have come across during your years is SED or the Stream Editor (sometimes referred to as the String Editor as well). This tool can take input from stdin and manipulate it as it leaves via stdout.

For those of you that have used SED in the past, you will certainly notice some similarities to the Cisco set of commands known fondly to many voice folks as Voice Translation Rules, and given your ability to pick out the differences, may help you in your quick adaptation to Cisco’s iteration of this tool.

For those of you that have not ever used this tool, take no worry. For in these next series of blog posts I will attempt to break down not only the components of Voice Translation Rules, but of the overall science of Digit Manipulation in IOS, into bite-sized chunks that will help you to digest it much easier.
