New Recorded Webinar on Firewall Configuration – NAT and Port Forwarding

For those of you who didn’t get the chance to watch the live webinar, we have made available the recorded NAT and Port Forwarding webinar for you to go through.

In this webinar we introduce you to the NAT and port forwarding required to allow the voice traffic to pass through the firewall and reach the PBX in each of the following scenarios

  • Connecting to a VoIP Provider
  • Connecting Remote Offices using Bridges.
  • Remote Extensions (3CXPhone)
  • Remote Extensions (IP Deskphones – Using SBC and STUN)

We also demonstrate the firewall checker, which you need to use to make sure that the port forwarding is properly configured, before proceeding to configure any of the above scenarios on the PBX.

Finally, we demonstrate the manual provisioning of a remote extension, using STUN.

Why is it important?

One of the most important factors in the setting up and configuring of a PBX is the network on which it resides. This is often overlooked, and usually not considered to be important, as traditionally, a PBX was totally independent of the corporate data network.

The network configuration is very important for the PBX, as it relies on the network to carry the voice traffic effectively and efficiently. If the network is not configured correctly, various issues with voice calls will occur. One of the most important network devices is the firewall, which is the main network protection device.

In order for the firewall to function as intended, it is important that it be configured correctly, to adequately protect the network and also allow the necessary voice traffic to enter the network and reach the PBX.

Another series of online trainings has already been scheduled so if you would like to participate in one of the live webinars all you need to do is register to the webinar of your choice.
