A lot Smoother Installation - VMPlayer Tip

I reinstalled the CUCM Publisher last night and the install went a lot smoother than a few months back when I attempted to install it on ESXi on an old HP server. VMPlayer worked surprisingly well even though it's not as convenient as VM Workstation.

The only issue I ran into was getting connectivity to the network which was a combination of things. It didn't like my trunk port on my switch so I changed it to an access VLAN (VLAN 100) for my server subnet. I also had to play with the VMPlayer network settings, once I changed my VM to following connectivity was established:

Network Adapter Settings:
1. Network Connection set to bridged mode
2. Check mark "Replicate physical network connection state"
3. Select the "Configure Adapters" button
4. Select only the Ethernet port or whatever port you use for connectivity, un-select the others.

Tonight I plan on installing the Subscriber and I have to get my hands on Unity Connection still from some where. I have a CUPS 6.0 DVD so hopefully that works when the time comes. At some point I need to run to Walmart or somewhere to pick up a crossover cable, I don't have good tools to make my own.

Rebuilt my Lab with PICS!

Finally got around to rebuilding and configuring my lab again, it's been a very busy year with a lot of changes. I have the majority of the basic configuration finished, I'm using the same design as my last lab before I had to give all of my equipment up. The only thing that I'm missing is a cross-over cable for my Branch IP Phone since I'm connecting it directly to my branch router. I believe this is the reason why it's showing as not connected, at least I hope. I'm using OSPF for the WAN

Not pictured is my beefy work laptop that's 8 core with 24 gigs of RAM or some thing crazy like that. I'm hoping I can get away with VM Player but I may have to go with some of the higher end VM solutions like Workstation or ESXi with a dedicated server if I run into to many snags.

My job role changed pretty drastically and I may not be touching voice as much as I did in the past, I'm being moved to the design and implementation space for my company. There will for sure be enough phone stuff to keep me occupied but it may only be 25% of my workload instead of 80% like my previous gig.

I'm thinking of finishing the CCNP: Voice track and then start moving sideways to CCNP R&S and then the Design tracks. maybe even Data Center stuff depending on how much deeper we get into it at my company.

Knocked out first CIPT1 Chapter

I'm off to a decent start but it could be a little better, I finished up the first chapter out of 16 from the official study guide. I looked around quite a bit and besides the quick reference book there isn't much study material for this exam besides going through one of the training vendors. Once I'm reimbursed for this first test I'm going to invest it into a Skeletek rack with all the goodies like cable management.

Passed the CVOICE Test!

It's about time! It took me a little longer than I expected due to a lot different outside variables but I finally got over the hump on this one. It took the following to get me through:

Books:
Cisco Voice Gateways and Gatekeepers
Cisco QOS Certification Guide
Cisco (CVOICE) Foundation Learning Guide (Kevin Wallace)
Sybex CVOICE 8.0 Study Guide

Videos:
Kevin Wallace 1 exam a month (1ExamAMonth.com)
IPExpert CVoice videos

Other:
Mnemosyne's
Forums
Lab's...a bunch of labs
Colleagues
Real World Experience


By far the hardest exam I've taken so far and there's 4 MORE to go before I'm certified. I can finally get back to building out my lab though. Hit hard on QOS, CUBE/Gatekeeper, VOIP Calculations, and Voice Signaling theories.

About Ready for the Retake!

After a hectic 4 weeks including business travel and settling into the new house; I finally finished the last 3 chapters of the Sybex CVoice book. I'm going to review and go over study notes for the next 3-4 weeks and hopefully have the CVoice scheduled and PASSED this time around. There's a good 5-6 network projects going on at the same time right now. 2 VoIP migrations and even 1 PBX migration happening within the next 6 months.

The PBX migration starts next week, I'm working with an outside consultant for this one. I finished the new dial plan to integrate them on to our CUCM yesterday. There's also multiple MPLS and IPVPN turn-up's happening around the globe. I have all the networking hardware I need to make my voice lab, I just need to purchase a rack for all this stuff and cable management. I'm looking at Dell 2950's for my VM environment, can't wait to have the lab built, but I'm looking forward to how much more I still have to spend for it lol.

Three More Chapters Until Test Retake

I'm starting to make some head way through the last book I picked up for CVoice. I'm hoping to have the last 3 chapters finished in another 6 weeks, it all depends on how busy I get at my gig. Right now I'm working my way through the H.323 Gatekeeper and CUBE chapter. Followed by the oh so famous QoS chapters. Looks like I won't be able to rent any lab time through INE for the entire month of July due to book camp weeks. That's alright I'm already planning and designing my new and improved lab, I plan on even getting a comm rack this time around!

INE Labs and a Quick MGCP Tip

Slowly but surely I'm making through the Sybex CVOICE book, I'm about 65 percent of the way the through. I've been going through the hands on labs in the book as well, utilizing the INE rack rentals since I'm unable to access real equipment at the moment. I'm not going to lie, just figuring out how to connect to their labs have been difficult...for me. I tried the VPNless method and the Cisco VPN client methods so far. Using the VPNless method I couldn't connect to a lot of the equipment for whatever reason. When using the Cisco VPN client, it seemed to work a lot better but I couldn't access anything else outside of the the lab rack.

I'm sure this has more to do with me than anything else to be honest with myself. The racks are designed for people prepping for CCIE so in the back of mind I feel as though my comprehension of the technology itself is preventing me to wrap my head around on how to correctly connect to their equipment. I may be wrong though, at least I'm able to accomplish what I need so far. I believe over time I'll become more familiar on how to properly connect to everything. If not I'm not afraid to ask for help.

MGCP TIP:

I'm sure most of you know this, in order for MGCP to work correctly and pull the XML file from CUCM, the name on the voice gateway and the CUCM must have the same exact name!

Well it was bound to happen but I'm finally broken in at my new job and made my first mistake that caused downtime for a few sites. I was tasked with installing a template on all of our gateways which included giving them our domain name.

The official syntax for this is ip domain-name domainname; the use of this command changes the name of the Cisco device. So if your device host name is called Gateway and you add the domain name to the device i.e. ip domain-name contoso.com, the official name for the device is now Gateway.contoso.com. Even though the device considers Gateway.contoso.com to be its name, the host name will still appear as just Gateway when you're staring at the CLI.

Unless you changed the name to Gateway.contoso.com on CUCM as well, it will not know how to reach this device. The trickiest part about this is that it doesn't rear it's head right away, Our gateways didn't use the new name until exactly 12:00 AM the following Saturday after I gave them their new domain info. Watch out for this!
