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....
2. You need to have an account with one of the VoIP providers in order to get a phone number for inbound calls.
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.
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
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.
