<div class="moz-cite-prefix">Given that most providers can port
existing numbers to SIP trunks. I would question the wisdom of
using Analog Line cards for anything. PSTN has the tendency to
suffer echo due to impedance mismatching and once you add the
delay of voip it can be quite noticeable even with top shelf
hardware echo cancellation. It's 2016 why not use a SIP trunk. <br>

<p class="MsoNormal">Afternoon all, normally we provide SIP only
PBX services for customers however we have been asked to
provide a SIP PBX with Analogue PSTN lines for inbound and
outbound calls.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We normally provide Elastix as a simple
cost effective PBX for small customers and in general it works
well for what they need.<o:p></o:p></p>
<p class="MsoNormal">I am looking for some wisdom from people
who have installed a decent 4 line card for use with Elastix
before quoting the customer as we had experience some time ago
with timing issues when using analogue cards with VOIP
handsets.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
