How Do I Run 4PSA VoipNow Express Edition from my Dedi?


Okay, though I'm not new to VoIP technology, I've never tried to install it on a server for use in my own business. I'd like to try this on my own and not lease a VoIP server or contract with a provider. There's no risk to my business if the VoIP VPS goes down because I have other virtual backups.

I want to run 4PSA VoipNow Express Edition on my dedicated server using VMware or some similar virtualization product. I'm running Centos 5.3 on a virtualization-ready, high quality dedi.

Other than the VoIP software, what else do I need? How do I get phone numbers? I know I need at least an IP address and have that available. But, I know little else and don't need a more than 10 lines.

If you have resources and positive, useful advice on how I can get this set up (read: please don't tell me why I can't or shouldn't try this at home but how I CAN do this successfully), I'd appreciate your input. Thank you.

April

1. VoIP does not work to well with virtualization it has a lot of timing issues. (VoIPNow is asterisk based product and it will not perform to well as VM)
2. You need to have an account with one of the VoIP providers in order to get a phone number for inbound calls.
3. In VoIP there is no such thing as a phone line ;-) if you need to be able to receive 10 calls to same number you need to a phone number that have 10 channels. In your case I would recommend you to shop for Virtual PRI, because most of retail VoIP providers provide you with 2-4 channels per number.

Any ways take a look at www.voip-info.org

Really? I'm not surer I understand what "timing issues" are, unless you're talking about dropped packets that causes issues like gurgling, broken up calls, disconnects, etc.

But, I wonder, then, why 4Psa would say that the express version can be set up in fewer than 10 minutes on a home desktop (which points to the VoIPNow server) or on a server using products like Virtuouzzo, VMware or similar virtualization software. It appears to be as easy to install this as to install Skype. (At least it would be for me since I'm familiar with installing and using virtualized instances of OSes on my computer and servers. This, supposedly, isn't much different if you have the right resources like dedicated IP addresses or, in the case of this software, a good broadband connection.) And, with right phone equipment (software or hardware) and internet connection, it should work as well as any hardwired or hardware-based VoIP phone solution.

In fact, the company offers a hosted solution called "VoIPNow Ready" that's offered on VPS. I mean, we ARE talking Racksoft here....

I probably should have done this before but I did a little more research and it appears that I need an account with a SIP carrier that provides phone numbers (not just VoIP services like a Vonage, which I DON'T want. Been there, done that. Want more control over my IP telephony.) That way, I can get connected the public telephony network and use phone numbers to get and make phone calls.

And, if find the right SaAS for VoIP, I may be able to get multiple phone lines (see below my response to "phone lines"), each with it's own phone number, which will be better for me since I have separate businesses and that sharing line thing doesn't always work so well, even with separate virtual phone numbers. It's rather like shared webhosting.

Okay, so, when I used a VoIP provider that gave me an adapter that included two separate phone lines, they weren't phone lines? I'm not trying to be snarky; I'm just saying I thought these were two phone lines. They rang to an analog desktop phone that had two lines and each line had it's own port on the adapter box. I've had two different phone lines on landline service (which seems like such an outdated concept now!) when I had VoIP service similar to Vonage.

And, my last VoIP provider provided me with two lines with up to 10 secondary phone number that rang to those lines. That, again, didn't work really well since I only had one voicemail box for each line but I resolved that by having the voicemail go to virtual phone numbers with their own voicemail. But, I'd still had to check all those phone numbers so I'd like to have a single, web-based interface, where everything is stored in one place (or two, if I do the failover thing).

Moreover, I'm thinking that, with the right SaAS provider, I can have that and more. I can have multiple lines that ring to whatever kind of phone I want, point to one IP address and have a backup IP/server if the primary goes down. I could even do the ".tel" or enum thing. Would it be as cheap as conventional VoIP phone service? No, but this kind of thing never is and I'm at the place where I need this level of sophistication AND the ability to be a digital nomad.

Finally, I've been on voip-info.org and it's too generic. It's like AOL for voip. It provides residential and SOHO solutions for business owners who have limited needs or only one or two businesses, usually sole proprietorships that don't have the IRS and UCC corporate law requirements. I have far more sophisticated needs than that and will be using this site instead: http://www.sipcenter.com/sip.nsf/html/Service+Providers and sites like 4PSA to find the right VoIP SaAS.

Thanks for your input but I think I was asking about a more sophisticated solution than standard, vanilla VoIP. Your response, however, DID give me a basis for understanding what answers I was actually seeking so, thanks. Sometimes, you need to ask the first question, no matter how unsophisticated it is, to be able develop your ideas and to formulate solutions. This exchange helped.

Now, I'll just figure out from whom I can get VoIP SaAS that works best for me, run this on my dedi using virtualization software, get the right SIP carrier that provides reliable service and go from there!

If anyone has solutions similar to the ones I've posted, please feel free to share. I appreciate positive responses like ydonchenko's.

April

I've never run VoipNow but if it runs Asterisk then it should work well on OpenVZ. You'll need to install the dahdi/zaptel dummy driver on the host node and make them available to the VPS if you want to run IAX2 trunks (an alternative to SIP) or MeetMe conferencing.

As far as numbers and call termination - yes there are hundreds of different SIP providers to chose from. Obviously you can set up trunks from multiple providers and see which works out best.

I'm going to try a couple of virtual VoIP solutions and SIP providers to see what works. I want to use the solution (SIP or IAX2) that most helps me stay mobile--a digital nomade. But I'll look at both setups. Thanks for you input. It's helpful.

Have you consider a Hosted/Virtual PBX by some of the carriers on a market that offer decent feature's set. Something like BroadWorks Sylantro or M6 (well now they all broadsoft) but it will provide you with reliable service.

From my personal point of view I would never put my business on any products that are based on Asterisk. Don't get me wrong it is a good PBX but I would not mess with it do to security issues in real world and a specially in hosted environment.

What features that are missing from Asterisk?

What security issues? They're normally pretty good at releasing security updates.

Not sure how much you have looked into 3cx.com Windows Solution.

"3CX Phone System is a free & they have a paid version VoIP PBX software for Windows that allows you to easily set-up a professional, modern phone system for your business!"

* Use popular VoIP providers and SIP trunks for low cost calling
* Use popular IP Phones (Polycom, Snom, Cisco & others) or Softphones
* Keep using your old telephone lines with the use of VoIP gateways
* Runs on Microsoft Windows - no need to dedicate a PC or learn Linux! Eliminate phone wiring
* Includes enterprise phone system features such as voicemail, auto attendant, fax server, unified communications and more


Callcentric seems to be a pretty good provider of SIP lines and Numbers.

I've downloaded and tested the free version on a stand alone machine runing XP Pro using callcentric's SIP line services.

I'm not sure but I guess you're agreeing with me? This from the link you posted -

Every IP-PBX will have its share of bugs and security holes, I get Cisco advisories all the time, so I wasn't too concerned when I heard about this security vulnerability in Asterisk.
But what amazes me is the fast turnaround to fix it - and over the major holidays no less!
Obviously anyone running software on the net (web, dns, ftp, voip ...) should make sure that it's patched as vulnerabilities will be discovered all the time.

This was a very unclear warning issued by the IC3, which they later reissued with some details of the vulnerability.

The vulnerability was discovered by Digum themselves and patched in March 2008. The IC3 warning was issued in December 2008, 9 months after a patch had been issued.

Again, as with anything, keeping your systems up to date with any security fixes is a good idea.

VoipNow indeed uses Asterisk only for some tasks, it features a more complex architecture that allows it to scale in hosting environments. Even if you run VoipNow on a VPS, you DO NOT have to load any Kernel timing devices. These are simply not required (unlike in Asterisk).

OF course, if you want to use physical interface cards you must load Kernel drivers for these, but I doubt that you want to do this.

Loading Zaptel timing drivers on OpenVZ for example is not recommended. It is relatively easy for a user on a machine with direct access to the kernel module to crash the entire hardware node. This is just a reason, there are also others related to system manageability.
