<div class="WordSection1">
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">My initial inclination is to tell you that it’s ok to go to the SIP server level. Here, we are running FreePBX, which is really just a web-based GUI for the Asterisk PBX system,
which is built on linux and runs on common pc hardware. Our phones are low end multi-line business voip phones.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">In our case, our current iteration uses the full OS with PBX system available as an ISO installer here:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D"><a href="https://www.freepbx.org/downloads/freepbx-distro/">https://www.freepbx.org/downloads/freepbx-distro/</a>. If one was so inclined, one could install FreePBX by hand,
or even Asterisk by itself, but then you would have to configure the system using text files on command line server, rather than in a web interface. It’s do-able, but not worth the trouble if it can be avoided.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">We’ve been using versions of FreePBX for at least 3 years now. We have had occasional issues, though none of which were game stoppers, and this system allowed us to move up to
voicemail, auto-attendants (in our case, for when we are closed), and other little things that one expects from a business phone system in the 21<sup>st</sup> century.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">The big gotcha that I would recommend looking up now, whether you go with a SIP trunking service or a hosted PBX solution, is to look up who can offer phone service in your current
telephone exchange. One of the things we discovered was that because of the legacy of a local phone company in town here, the only places offering any phone service to a 937-855-XXXX number were the local POTS provider and TimeWarner. In our case, we realized
this about halfway through the process, and in the end purchased analog adapter boards for our PBX pc and went with TimeWarner business class for our phone service. This didn’t save nearly as much money as a full on sip trunk provider would have, and our
PBX cannot do as many interesting and useful things as I had wanted, but in the end we now have a modern phone system, long distance in the US and Canada are included in our TWC service at a cost that saves us a few bucks per month over the local POTS provider.
Our system is currently pushing 12 phones with 3 analog phone lines connected through the adapter.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">One other gotcha I would mention is that you will want to be especially careful about your firewall settings. I’m not sure what it would be like working with a hosted PBX voip
provider, but with the sip providers I worked with, they all recommend port forwarding several ports to the PBX system through your firewall, and at one point I had to rebuild the installation because “something” on the PBX started sucking up pretty much all
of our bandwidth any time the PBX pc could see the internet. (I consider myself lucky at that point that I had the PBX and phones physically segregated from all of the ordinary PCs in our building)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">I’ve since learned that there are ways to open ports exclusively to specific external URLs or IP addresses or ranges of IP addresses, and I would recommended that you either know
how to do that on your current firewall, or find a firewall that can do such things without a lot of suffering on your part.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">One nice thing about a system like FreePBX/Asterisk, is that because it is built on top of command line linux, it requires very little hardware. For the first few years, we were
running the system on retired public PCs that were somewhere in the 7-10 year old range. This year we upgraded the system to where we are now using an off-lease thin client with a USB stick for a hard drive.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">So, long story short, if you go this route, just about any current PC hardware will be adequate for your needs.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">If you are tempted to try to go this route, one thing I would do is setup a rudimentary test system, to ensure that there are no odd networking issues that would interfere with
calling when you have a PBX at your main library and some of the phones in remote locations.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">If it works, a freepbx setup with a sip trunking service would likely minimize your monthly phone costs.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">That said, something like a hosted PBX system with the same off the shelf phones is liable to show a decent savings over your current setup and would require less work/learning
on your part on the front end and would be one less system to maintain in the long run.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1F497D">Best of luck and have a good day.
