Auto-Registration vs Manual
Here's one of the debates that never gets old; to use or not to use auto-registration on the lab is the question? Well in a"real world" enterprise situation with hundreds or even thousands of phones, Auto-Registration and the BAT tool may be the way to go. However, being that we will have anywhere from 6 - 9 phones (give or take a phone or two) on the lab, I can't just jump out the window and say "Auto Reg" is the way to go. Why not? I'm glad you asked.
One very simple reason: It depends on what the lab is asking me to do!
If I am tasked with using SCCP and SIP phones then I will MANUALLY add the phones to the database. I have had nothing but trouble letting auto-registration do it for me in a mixed environment. The process of changing a phone from SCCP to SIP and vice versa is not difficult at all; however waiting on the phones to actually do it is a whole nother beast and I do not care to waist any of my time in the lab waiting on a phone to get it's head together. I have been able to manually add the phones to the database with relative ease and quickness, plus copy and paste is a great tool to have.
Conversely, if I am tasked with using one protocol or the other and not a combination of the two then I will use auto-registration. All I will need to do is go to System ==> Enterprise Parameters ==> Auto Registration (cluster wide parameters) and make sure the protocol is whichever one the lab guide says to use, save, and restart the CUCM and everything will be honky-dory in happy land.
Well that's my take on it; I will holla at y'all later!!!

Resetting Cisco 7961 IP Phones…
I don't have a lab at home so I rely on rack rentals from the great gang over at IPExpert and Proctor Labs. I knew coming into this that financially I didn't have the capital that is needed to build a complete voice rack so I did what I thought was the smart thing to do and use remote racks with some hardware here at the cave. So I have a 2611XM router, 3550 POE Switch, 3 x 7960 IP phones, and 2 x 7961 IP phones. The 7961 phones are new to the equation (bought used off of eBay). Well during my lab session today I decided to break out the fancy smancy 7961 phones so I could practice some SIP crap when I found that the phones needed to be reset to factory default. ARGH!!! X-(
Being that I have never had to do this I did what any self respecting engineer would do; hit Cisco.com and searched for the procedure to do it. I would be lying if I said that finding the information on Cisco.com was painless, as with most things you search for on their awesome website, it was downright a pain in my john-brown hind parts. Well anyway, I found the procedure and tried it out. Seems like it worked so well I decided that I would let all of you know what to do if you ever need to reset one of these phones back to factory default. It's a pretty painless process with the exception of having to upgrade the firmware on the stupid phone. Anyway here you go.
- Unplug the power cable from the phone, and then plug in the cable again.
The phone begins its power up cycle.
- Immediately press and hold # and while the Headset, Mute, and Speaker buttons begin to flash in sequence, release #.
The line buttons flash in sequence in order to indicate that the phone waits for you to enter the key sequence for the reset.
- Press 123456789*0# within 60 seconds after the Headset, Mute, and Speaker buttons begin to flash.
If you repeat a key within the sequence, for example, if you press 1223456789*0#, the sequence is still accepted and the phone resets.
If you do not complete this key sequence or do not press any keys, after 60 seconds the Headset, Mute, and Speaker buttons no longer flash, and the phone continues with its normal startup process. The phone does not reset.
If you enter an invalid key sequence, the buttons no longer flash, and the phone continues with its normal startup process. The phone does not reset.
If you enter this key sequence correctly, the phone displays this prompt:
upgrading
Hope that helps...
162 Days and counting…
Ok I know I know I know, I keep saying that I am going to do better about updating my blog and I promise you I mean well. I am certainly going to start doing better; I promise (again).
Anyway, what's new with you guys? Nothing much has changed with me, except I have rescheduled my lab (again). I am now locked in and scheduled for September 24, 2010 at Cisco's campus in San Jose, CA. That's why this post is titled 162 days and counting.
I have made a new friend on the CCIE Voice Prep scene, Matthew Berry over at CiscoVoiceGuru. Check his blog out when you get a chance. If there's anyone that has a legitimate shot at passing the v3 Voice lab on their 1st attempt it's Matthew.
Also while it's on my mind check out my buddy Dave's blog over at CCIE Voice Guide. He is another one that I believe who has a legitimate shot at passing on their 1st attempt.
Oh yeah, the big announcement that I had in store a while ago. Well it's no longer a big announcement. If any of you were wondering what it was, trust me it was huge, just follow me on Twitter and DM me and I will tell you.
That's about it for now. I am still labbing it up and studying all I can. I think I may take a minute or two and post what my study schedule is. Let me know what yours is and let's see if we may be able to help each other get over the hump.
