Iphone 3G IOS 4 upgrade failure - Resolved

-
Are you experiencing problems upgrading your iPhone 3G to the latest OS4, then read on.

When initially attempting to upgrade the iPhone to the latest version, my phone was struggling with backing up the the contents of the phone. An error message appeared later on but unfortunately I didn't make a note of the error however, I couldn't find the error code in the log files for iTunes either.

1. Open iTunes, right click "Your iPhone" and click Transfer Apps. Unfortunately, this will mess up the order the apps are laid out on the phone but this enables you to backup your apps and remove it from the phone and return it at a later date. This is helpful if you want to keep the app but are short for space. Also, under the Apps tab, tick Sync Apps if it is not already ticked.

2. Untick Sync Music under the Music tab, this will significantly increase upgrade time as the music won't be backed up. (Its on your computer anyway - if its not then, then I wouldn't complete this task)

3. Right click "Your iPhone" and click "Back up".

4. Click "Your iPhone" and under the Version section, click "Restore" and when prompted, click "Restore. After the restore process is finished, the new OS4 will be installed. After the install is complete, you will be prompted to restore a backup you made earlier. Click the button which indicates you want to use the backup of the phone your previously made.

5. Click the Apps tab and tick the apps you want to sync with your iPhone.

6. Congratulations, you are now using OS4 on your iPhone.

I accept no responsibility for any loss of data by attempting the method above. It worked for me, so I thought I would make an effort and share it with the world.

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. http://www.ipcommute.co.uk/technical-articles/17--creating-isolinux-boot-dvds-with-free-software-cucm-uccx-c...

Hi All For my reference and your's, here is a working sample configuration for configuring sipgate (sipgate.co.uk) for incoming and external VOIP calls on a 2800 series Cisco router. Using GNS3; My wireless adapter has internet connection sharing enabled, and I have created a loopback adapter which is the 'internet' adapter as you can see below. I have tested making calls using Cisco's CIPC version 8 and receiving calls. This doesn't have to be done in GNS3, just pick up yourself a real voice gateway. version 12.4 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname VG-EP ! boot-start-marker boot-end-marker ! ! aaa new-model ! ! aaa authentication login http local aaa authentication login ssh local aaa authorization exec http local ! aaa session-id common ! resource policy ! memo...
