<p>Most of the big names in HPBX built their own:</p>
<p>ShoreTel, RC, Fuze, Digium, Fonality - built their own</p>
<p>8x8 built there are; hold about 90 patents; and is one of the
most successful HPBX company at $230M in annual rev.<br>
</p>
<p>Vonage - has 2 home brew + BSFT (over 600K seats on VB)<br>
</p>
<p>Dialpad - Freeswitch</p>
<p>Nextiva, DSCI, Momentum, XO, VZ and 400 more are on BSFT</p>
<p>15 Million lines on BSFT - more than 3x the next vendor for UC
(Cisco)<br>
</p>
<p>Downside to that is that the patent trolls win, time and again.</p>

<p>Combined Level3, VZ, Sprint, AT&T have over 500 VoIP patents.
That will bite you eventually. I see patent trolls regularly
attacking clients.</p>
<p>BTW.....<br>
</p>
<p>It isn't the technology. It is knowing who to target with what
bundle and what message - and then getting out there to sell it. <br>
</p>
<p>There are plenty of open source VoIP companies who have failed
miserably. Quite a few on Meta and BSFT.</p>
<p>Much of it has to do with product/market fit; marketing and
sales. Those last 2 - marketing and sales - are like kryptonite to
most folks who go open source. Why? They get stuck on the tech.
It's all about features and custom and blinking lights. That
doesn't appeal to a buyer.</p>
<p>Open source has its own challenges: patents and skill set. You
have to have full stack devs and engineers to run your own
platform. One CEO who switched from a commercial to home brew
spent all of his licensing dollars on a team of devs and engineers
to keep the cluster running.</p>

<pre wrap="">Another +1 here for open source.
I came to the open source side after working with Broadsoft and Acme
Packet... finding out that not only could we reduce unnecessary costs
with an open source model, we could also improve the customer experience.
Projects such as Asterisk, Kamailio, and FreeSWITCH are mature, tested,
and trusted by large institutions, carriers, governments, and more.
If you don't want to build your own, there's great products out there
building on top of open source, such as:
CSRP
<a class="moz-txt-link-freetext" href="http://www.csrpswitch.com/">http://www.csrpswitch.com/</a>
high-performance SIP "Class 4" call routing platform for VoIP service
providers of all kinds
Kazoo/2600Hz
<a class="moz-txt-link-freetext" href="http://www.2600hz.com/">http://www.2600hz.com/</a>
and... of course... you can always build your own (or hire a consultant
to help you).

It's taken by a significant percentage of the industry.
No, open source is definitely not free. But to those accustomed to a
Broadsoft-type experience, I think there are a lot of misconceptions
about it that stem from a lack of familiarity with how to approach the
open product ecosystem. There's a perception that it's "highly
technical" or, "Okay, I got FreeSWITCH to compile. Now what?"
In reality, there are _lots_ of "packaged" answers to this problem, if
you're just willing to look. If you don't want to build anything
yourself, there are many good commercial systems built on top of an
open-source technology stack. They cost some money, but nothing on the
order of the big brands, and are competitive and growing in the larger
operator and enterprise markets. Example:
<a class="moz-txt-link-freetext" href="https://integrics.com/enswitch/">https://integrics.com/enswitch/</a>
It's built on top of Asterisk, Kamailio and MySQL, but very turn-key.
If you have the engineering core competency to build something yourself,
the ROI is excellent. Yes, there's a cost and a GTM lag, but once you
sink the cost, nobody's going to hit you up for $MEGABUCKS for another
100 seat licences ever again. And again, it doesn't mean you have to
write a million LOC multitenant software product yourself.
There are lots of people on this list who provide hosted PBX with
Asterisk or FreeSWITCH and have not had to do this. There are many
approaches; you can certainly roll a home-spun multi-tenant platform if
you really want to, but you can also sell individual instances of
ready-to-go PBX distributions to customers inside a virtualised or
containerised environment. In the latter, the port density / unit
economics relative to hardware are excellent. You can put 100+ such PBXs
on a single commodity box. Automating deployment with all the tooling
out there these days isn't that hard. A lot of the tools already exist
in FOSS land, if you just look around. And you can use feature-rich (and
easy white-labelled) PBX distributions such as FreePBX or FusionPBX out
of the box. Just Google around.
The companies who have put a little bit of work into this have
definitely forked out some CAPEX (mainly engineering time or
consultants), but their ongoing OPEX commitments are comically low, and
accordingly, their gross margins and cash flow are that much the better
for it. What's more, the sunk cost tends to be largely fixed, so your
ROI gets better and better with subscriber growth.
It's not for everyone. Some organisations are sales-heavy cultures best
suited to selling cookie-cutter products and don't want to do anything
nerdy, or can't. But there are lots of people on this list making
excellent money with open source, and I count some of them among our
customer base (though we are not in the C5/hosted PBX platform
business).
