How does Switchvox's VPN utility work?

For assistance from Tech Support, you may be asked to enable VPN access, in the Switchvox admin interface. 
 
Switchvox uses OpenVPN, to create a secure connection between your Switchvox and Digium's portal access server. Below are some key points to connect successfully:

• To enable, select Server > Technical Support > Technical Support Access: ENABLED.

• Digium Technical support provides a password. (Generated for each individual VPN session.)

• Communication occurs via UDP traffic, on port 1194. (Ensure this port is open between Switchvox and Digium.)

• Your network must be able to resolve portalaccess.switchvox.com (Digium's server) to IP address 199.248.63.85.

• Ensure Switchvox is not blocking 10.138.0.1 or 10.139.0.1, on the Server > Blocked IPs list.

• Port 22 (SSH) should not be open to the public, from the PBX.

• Selecting “Connect” makes an outbound connection to “portalaccess.switchvox.com:1194”.

• Switchvox must be registered.

After troubleshooting, close the VPN tunnel by disconnecting Technical Support Access, in your Switchvox admin interface.
