Get Root Access to CUCM, Cisco Unity Connection, UCCX just like Cisco TAC in less than a minute.
Most of you might know that we can root Cisco Unified Communications Manager (CUCM), Cisco Unity Connection (CUC) or Cisco Unified Contact Center Express (UCCX) using CentOS or Linux OS. That is a long process where you need to shutdown the platform, boot the platform with CentOS or Linux and then root it using some commands and then turn on the platform. This is time consuming and it takes around 15-30 minutes. In case you have not gone through this process, here is the article.
Note: UC Collabing does not recommend to try and apply it on your production server and will not be held for any damages that could occur in your system. In case you perform this on your production servers, you may void Cisco contract. This is only for lab and learning purpose!

Here is the step by step process to root your UC Appliance.
- Login to CUCM/UCCX/CUC which you want to get root access using SSH.
- Enter the command : utils remote_account enable

- Enter the command : utils remote_account create rootuser 30 (The remote account name will be “rootuser” and it will be valid for 30 days only)
- You should receive a message as “Account Successfully created“.

- Click on Tools > Click on Decode Passphrase
- Now copy the Passphrase which was generated from the CLI and enter it into Remote Support Passphrase.
- Now open a new Putty session and login to the CUCM/CUC/UCCX CLI which you used in the above steps.
