PowerMedia XMS Installation

This section provides the steps required to successfully install PowerMedia XMS.

There are two installation methods available:

  • ISO Method

  • RPM Method (used for a CentOS or RHEL installation).

The following instructions pertain to the PowerMedia XMS download package, labeled as PowerMedia-3.0.xxxx-x86_64.iso and dialogic_xms_3.0.xxxx.tgz where "xxxx" indicates the version number.

32-bit operating systems are not supported.

  • RPM Method Installation: CentOS 7.x and 6.4 (or later) Red Hat Enterprise Linux (RHEL) 7.x and 6.4 (or later) Oracle Enterprise Linux (OEL) 6.4

Download the .ISO file, which contains CentOS and PowerMedia XMS packages. Go to for information about downloading the .ISO file.

Supported Virtual Machines

The supported virtual machines (VM) are:

  • VMWare ESXi 5.x

  • Kernel Virtual Machine (KVM)

  • XenServer VM

  • Oracle VM VirtualBox

XMS installation in Oracle VM

Create new virtual machine (VM)

  • Name: Any suitable name (XMS)

  • Type: Linux

  • Version: Other Linux operating system 64 bit

  • Recommended memory size 1024 MB

  • Create a virtual hard disk

Select the following options while setting the virtual machine:

  • VDI (VirtualBox disk image)

  • Dynamically allocated hard disk

  • Recommended size 8GB

Go ahead and press the Create button to finish up this part of the process.

Find and select the newly created virtual machine.

  • Open the Settings for the created VM. Under "Storage", press "Add optical drive" and select the PowerMedia .iso file image.

  • In case there is Empty storage attachment in the storage tree, delete first.

Start the VM and choose between DHCP and Static IP installation. The Static IP option is preferable when setting up a server. Select the second option and press "Tab".

Refer to the following example when setting static ip address nameserver=
The IP address should match the MS_ADDRESS in the restcomm.conf

The install process will begin and the next prompt will be to select the installation destination.

Select "Automatically configure partitioning" and press "Done". For manual configuration select "I will configure partitionig".

When the partitioning is done, click "Begin installation".

Once installed, open the Settings and change the boot order.

  • Under System, change the boot order. Select only “Hard Disk”.

  • Change the network configuration under Network. Attach “Adapter 1” to “Bridged Adapter” and select wlan0.

  • Reboot the VM

Now we should have running XMS instance on CentOS.


In case XMS doesn’t have connection, check the ifcfg-enp0s3 config file.

  • Login as root. The "root" user’s default password is "powermedia".

  • Go to /etc/sysconfig/network-scripts/

  • Open and modify ifcfg-enp0s3 config file. "sudo vi ifcfg-enp0s3"
