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.

VoIP has been implemented in many businesses because of its cost-effective ways, easy setup and features. It is one of the top five expenses in a business. Yet it’s not uncommon for many companies to have little or no provisioning for their voice systems when there is a disruption. A failure in the phone system could be detrimental to a company it could mean loss of customers, loss in revenue, important information received etc. A plan for data backup and restoration of electronic information is essential. It’s hard to understand why businesses forget about voice when it comes to disaster recovery.

Virtually all VoIP system manufactures, and most distributors have disaster recovery programs that deal with disasters. Unfortunately, these disaster recovery services are different from normal contract activities and it may be an additional cost to your bill.

Do not rush through the process of selecting a VoIP Provider. First, define your fault tolerance and according to that find out all the details about security and guaranteed. Be sure in asking the company you will go with if they do in fact have a DRP program in case of disaster. Also, investigate in adding a third-party firm that specializes in the backup/recovery of voice communications systems.

If you have your own VoIP deployment, then you need to create your own disaster recovery plans. The backup option could be a mirrored PBX system in the cloud or a hybrid deployment. The bottom line is that you need another option if disaster strikes your office. Gladly for everyone, OKay can help you on this.
