A Few Pointers about Security

Every now and then I hear questions on how to secure servers and especially how to secure voice traffic. We hear lots of myths from our customers :).

Most people feel more secure if they have a simple firewall installed.

While firewalls are good, having a firewall to protect closed ports usually doesn’t help. I mean for VoipNow you will probably leave opened all ports for VoIP services and close most of the others. My question is: what is the point of doing this at server level, if the ports are closed anyway? This makes sense on a consumer desktop, but on a server it usually does not help much.

Why Is 4PSA Orange?

I’ve been answering to sales inquires for many years. Most of the questions are of course related either to Unified Communications or to the hosting world and sometimes they can be very funny. For example, a couple of days ago, someone asked me why we’ve chosen orange as our brand color.

You are the Customer – Basic Questions to Ask about UC Services

We wrote much of the material below in 2008 for a whitepaper, but things haven’t changed much. That’s why I want to give some advice to small companies that want to choose a hosted Unified Communications service; hopefully they will make a better choice.

The key is to always ask the service provider before taking any purchase decision. There is no perfect software or perfect  solution, but the vendor must be aware of that and he must know how to get closer to perfection. Enjoy the following questions and do not hesitate to ask them before choosing a hosted service. Although they look quite simple, you might be surprised about what kind of answers you will get.

OXtender for Plesk version 1.0.1

Quickly after the first version, we released a new version that features extended compatibility. We got many requests from customers complaining that they run Plesk 8.6 and they are not able to use 4PSA OXtender. Starting with version 1.0.1, you can use OXtender with any Plesk version higher or equal to 8.3.0. We also fixed some minor bugs and introduced new functionality, maybe the most important being that the new version can work with email passwords that are encrypted in the Plesk database (it requires IMAP auth module on the Open-Xchange server).

Impressions on WebhostingDay 2010

I am writing this in the plane, coming back from WebhostingDay 2010. The event took place in Bruhl, Germany. From our perspective, the event was much better than last year and this happened due to the growing hosting providers’ interest in Unified Communications. Many people heard and understood our message, even with the small resources put on marketing. I will resume below the most important things about WHD 2010.

VoipNow Licensing Changes Explained

Starting with March 1, 2010 we changed the licensing methodology on VoipNow Platform. VoipNow Core is now more affordable for small customers with the new, dedicated server license for up to 250 concurrent calls. While this is a single server license, it expands to a 4Grid infrastructure able to sustain as many calls as you like. The pay as you grow, infrastructure wide licensing method is still available. In a service provider environment VoipNow Professional is available on pay as you grow licensing and also on dedicated server licensing for a small number of extensions. Perpetual (owned) licenses are available only for business customers.
