for the reply, there is no reasonable infrastructure at this

<p class="MsoNormal">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>
