Create bootable CUC CUCM CUP Image / ISO

The following script allows you to automatically create a bootable CUCM/CUC/CUP image without the need for any paid for software when you only have access to the update outside of put or the datastore for the new server. I have spent several hours on this, but I just wanted to make it simple. Only really for lab purposes, the checksum will fail due to the ISO being manipulated but essentially once you fill in the variables, you will just be left with a single ISO file in the staging directory.

To use;
1. Download the mkisofs.exe file as described in the script
2. Paste script below into Powershell ISE Script Editer
3. Modify the variables
4. Execute the script. Simple.

Tested creating an ISO on a Windows 10 machine and running the ISO on a ESXI server.

Thanks for this guy Aaron Harrison as per the URL, was helpful in the finding out the mkisofs.exe command syntax.


UCCX Phone Books - Powershell

The UCCX Server Documentation API for Phonebook's was slightly out of date, so I have referenced in my blog for future use.

CUCM 11.5 - Esxi 6.5 - unable to create VM

Hi Guys

Had an issue where I was unable to deploy a Cisco Unified Call Manager 11.5 OVA to the VMWare Esxi 6.5 standalone server.

The following error would appear during the provision of the VM - "At least one extra disk image was provided that will be ignored".

The solution to import the Cisco OVA into VMware is to use VMware's OVFTool. The commands I used worked for also UCCX and Cisco Unity Connect -

Restoring Cisco Unified Attendant Console Advanced V12

I recently had an issue where I needed to complete a restore (new build) of Cisco's Attendant Console Advanced V12 in order to satisfy testing criteria. I followed Cisco's documentation (CUACA_120101_Install-Guide.pdf) however the steps were not completely clear. The solution that I am working with here is a standalone deployment.

Delete all devices and numbers related to Cisco Attendants Console in CUCM. These include;CT Gateway DevicesService DevicesPark DevicesCTI Route PointsNumbers related to the above (directory number in CUCM)
You may need to refer to your low level design to find this information out. In the CUCM, the descriptions for these devices are prefixed with ASD. The devices are names are prefixed with PD, SB, GB and RB. Setup new server using OVAInstall the same Windows OSEnsure the hostname of the new server matches the name of the old serverRestore the CUACA crypto keys including aeskey.dat - these need to be taken from the live publisher by clicking Help / Ex…

Convert IMCEAX to X500 Address for NDRs

Paste this into Powershell ISE and modify accordingly.

This script will replace all parts of a problematic X500 address into a readable format when an NDR is delivered.

Example IMCEAEX value -

$x = Read-host 'Enter IMCEAEX full value'
$x = $x -replace "IMCEAEX-_", "X500:/" -replace "\+20", " " -replace "\+28", "(" -replace "\+29", ")" -replace "_", "/" -replace "\+2E", "." -replace '@.*', '';cls;Write-output $x 

Understanding VLAN Access Filters

Evening All

I've spent a few days trying to get my head around VLAN Access-Maps and VLAN Access-Filters. I am sharing my configuration which works fine in my GNS3 lab. This is not been tested in a production environment so I would advise caution and some thorough testing before bringing into a live environment.

So above is my test environment for VLAN Filters. Layer three is done on Router 1. I did actually try it on the L2 Switch however I couldnt get intervlan routing working so I had to use the Router.

This is what is allowed  -

Communication both ways between and both ways from to  I have provided a limited output of the switch. Basically, I am covering the access-lists, VLAN configuration and interface configuration for review. If you don't create the MAC access-list and apply it to the VLAN access-map, then the endpoints will not learn the IP address of the other end points. You can be restrictive and say, only allow…

Windows 10 Wireless connection asking for proxy server credentials

When using Windows 10 on a domain network, the wireless may show attention required and upon clicking the wireless connection name it disconnects and states "enter proxy server sign-in info".

In the background, the client machine is making a connection to As the computer is not authorised to use the internet, but rather the user this was the cause of the popup. I whitelisted the domain for computer authenication and now the wireless connects with no requests for further authentication.
