Minimal Cloud requirements:

  • Vmware ESX 5 or 6
  • 64-bit infrastructure only
  • E1000 NIC emulation or VMXNET3 interfaces
  • One Ethernet adapter for management (mgmt0)
  • One or more Ethernet adapter(s) for SIP and RTP traffic according to the table below (LAN/WAN)
  • If you are deploying FreeSBC in a 1+1 configuration, you need two (2) additional Ethernet adapters to be used as control ports (ctrl0/ctrl1).
  • If you are deploying FreeSBC with transcoding devices, you will need four (4) additional Ethernet adapters to be used as control and transcoding ports (ctrl0/ctrl1, trans0/trans1).

More details on HW/CPU/NIC requirements can be found here: Requirements Matrix

For better performance use these settings:

  • CPU resource: allocation shares set to 'high'
  • CPU resource: reservation set to maximum and no limit (i.e. 'unlimited')
  • Memory resource: reserve all guest memory (all locked)
  • Disk: shares 'high'
  • Advanced CPU: Hyperthread core sharing to 'None'
  • Latency Sensitivity: 'High'

Installation on VmWare cloud

FreeBSC VmWare Image

A virtual machine image is a single file that contains a virtual disk that has a bootable operating system installed on it. Images are used to create virtual machine instances within the cloud.

You will need to upload the latest FreeSBC image into your VmWare before you can launch a virtual machine instance running the FreeSBC software.

Launching an instance

Using the ESXi Web client

Using the vSphere client application

If you are installing a standalone SBC, the FreeSBC will need access to LAN/WAN and MGMT networks. For transcoding on TSBC-HW-TRANS, or HA pair installation, the FreeSBC will also need access to CTRL0/CTRL1, and TRANS0/TRANS1 networks. In both instance launching methods above, when editing network adaptor, please take reference to FreeSBC Networking for details on network requirements.
For FreeSBC Transcoding and associated network setup please also see FreeSBC:Transcoding and Network Setup.

Accessing the FreeSBC

Assigning IP address

By default, all detect network interfaces will have DHCP enabled. Thus, the server might already have an IP address assigned if the network has a DHCP server running. In such case, you can display and use it to access the web portal configuration panel.

  1. Retrieve an IP address assigned by DHCP
 # ifconfig

If you want to assigned a static IP address or there are no DHCP on your network, you will need to configure it manually.

  1. Use tbchangeip shell command and answered questions to changed your Ethernet interface address:
 # tbchangeip

Accessing the FreeSBC web portal

  • Open a web browser to the management IP of the FreeSBC, on port 12358. Example if your server address is, the URL would be:

You should get to the FreeSBC Configuration Wizard

  • If you do not know the IP address, you can find it from the VMware interface:
