Hi. At the current time, we have only tested the Linux version of Prophecy 9 on CentOS and Red Hat Enterprise Linux, and that is initially what we plan to support for customer production deployments.  You are, of course, welcome to download P9 for Linux from http://www.voxeo.com/prophecy/ and install it on Fedora 7 or any other version of Linux – we just cannot yet say ourselves whether or not it will work. We will certainly do our best to support you running P9 on F7. Our only caveat is that at this time if a problem looks like it comes down to an OS-version-related bug, we may not be able to make a fix as quickly as we would if it were CentOS or RHEL.

Thanks for your interest and if you have a (free) developer account at http://evolution.voxeo.com/ you can look through the support forums there and post comments, etc.

i need Prophery for Fedora 7. Please help me

Yes, the wall of servers is *very* cool and we’re very much looking forward to making that available for everyone to try out in a forthcoming beta release of Prophecy 9.

Your question about Prophecy is a bit complicated primarily because the answer really depends upon how you expect your traffic to flow. As you note, the free version of Prophecy is limited to 2 simultaneous lines and after that you pay on a *per-port* basis. In contrast, for an application in our hosted environment, you pay on a *per-minute* basis. Yes, odds are that the hosted version will be more economical for bursting to several hundred simultaneous calls.

In the “hosted versus premise” debate, we generally ask questions like these:

1. How “mission critical” is your voice application? Unless you’ve already built out your own massively-scalable, geographically-dispersed, redundant data center network, odds are that our hosting environment will probably provide a more reliability in ensuring that your voice application is always available. On the other hand, if you don’t need that level of reliability, a premise deployment may work fine.

2. What does your traffic profile look like? If your traffic is fairly “steady state” and fluctuates within a small zone, a premise deployment may make sense because you can purchase only the number of ports you need to cover the high end of your usage. On the other hand, if your traffic is “bursty” and has wild fluctuations in volume, a hosted solution may make more sense as you only pay for what you use.

3. Are there security/control requirements within your organization? Sometimes organizations have very specific process/requirements that state that all customer-facing servers/services must be behind the corporate firewall. In that case you may have no other option at all except for a premise solution.

4. Is a fixed-cost solution a requirement? With a premise solution, you pay only on a per-port basis. It’s therefore very easy to arrive at a fixed cost for your voice application solution. With a hosted solution, your cost depends upon the usage and so it may therefore vary, potentially widely depending upon your specific application.

Analyst Nancy Jamison went into these factors a bit more in a white paper she wrote last year at:

So to answer your final question about where racks of Prophecy servers make sense, one scenario might be where you have an application that makes or receives a relatively stable number of calls and is either not a mission-critical application or is deployed in a data center environment providing that kind of reliability.

Thanks for commenting and I hope this helped.
