Since release 3.6 of FusionPBX, it is possible to deploy a voice over IP solution on the cloud that satisfies next characteristics:

  • Balancing: Servers split the load among them depending on different network conditions;
  • Cluster: Servers know their peers and they send sync information to each other;
  • High Availability: Servers detect when a pear is down and they split the load among them.

This solution works without Kamailio.

VPN, a term that usually is not well understood, means the access of a remote network like if it were local. A VPN is archived using a tunnelling technique which consists of passing one protocol within another. There are several ways to do a tunnel:

  • IP over IP like the old good times,
  • Through another protocol such as GRE like PPTP does,
  • Using a Layer-4 protocol such as TCP or UDP like OpenVPN does,
  • Passing within a Layer-5 protocol such as DNS like Iodine does, or
  • Using a Layer 7 protocol like HTTP.

Security is an add-on that has been per defacto in the VPN's implementations but that doesn't mean it is part of the concept.

In this article, we are going to talk about the OpenVPN and Iodine (DNS) approaches.
