<div dir="ltr">Hi, I don't know if my experience will be useful but we have a running installation with 5 x A108E Sangoma Boards for a total of 40 E1 (1200 TDM channels) and it works fine with any issue. We do a mix of IVR and ISDN-SIP bridging. Our server is old (HP DL380 with two xeon 5520 and 16Gb ram) so a couple of new CPUs (for example xeon E5-2650V2) will handle your load for sure.<div><br></div><div>Stephen </div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Oct 23, 2014 at 11:59 PM, Andrew Keil <span dir="ltr"><<a href="mailto:andrew.keil@visytel.com" target="_blank">andrew.keil@visytel.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
