Configure CUE to Reference the Loopback Address
I have been going back and reading through a lot of the SRNDs and configuration guides to refresh everything that I have been going over in my lab. I came across one very interesting tidbit of information that I must have glanced over before regarding CUE and configuring the service-engine to reference the loopback interface.
In all of my practice labs from IPExpert, you are always instructed to use the voice VLAN for the CUE module. So, using the ip unnumbered VLAN 400 command does not pose any problems. However, when I attempted to issue this same command, but swapping Loopback 0 for VLAN 400, the router started throwing all sorts of errors. I was able to session into the module, however it did not have any IP connectivity outside of the local router.
Progress Update
In the last month and a half I really haven’t had much time to post anything. Between gearing up for my lab attempt on the 17th of December, the holidays and the vacation I just got back from, the last 5 weeks have really flown by.
For those of you wondering if I passed my exam on the 17th, I did not. I was close, but close only counts in horse shoes and hand grenades. I was able to make it through the entire exam, but I spent too much time on certain sections and ultimately ran out of time to go back and tweak things that were not working.
Countdown: 24 days…
and I am starting to feel the pressure. Need to work faster, smarter and harder….
That is all
Home Lab – PSTN Phone Configuration
I have been contacted a few times by people that are running into problems getting their PSTN phone working in their home lab. This can be a little tricky, especially if you are just starting out in your CCIE Voice studies.
Your PSTN phone is going to rely on CUCME as well as very heavily on voice translation rules and profiles. If you are not familiar with either of these I would highly recommend reviewing the CUCME Admin Guide before starting to set up the PSTN portion of your home lab.
In my home lab I have a Cisco 2811 acting as my PSTN-WAN router. I have this 2811 as well as a 7961 IP phone connected to my Cisco 3560 switch. Below I will outline my 3560 and 2811 configurations that are relevant to getting the PSTN phone registered and assigned its configured numbers. I am assuming that you have already configured the PRI portion of your PSTN-WAN router.
CCVP Out, CCNP Voice In
Cisco has announced that as of yesterday Oct. 19th, 2010 the CCVP certification is no more. Well, at least it is no longer called CCVP, it has been officially renamed CCNP Voice.
It seems that since they have refreshed the CCNA Voice exam, they want to create a clear path for their voice and unified communications technologies. Both the CCNA Voice and CCNP Voice tracks were updated and/or renamed to reflect the convergence of data and voice on the same network.
