<div>Thanks for reply.</div><div> </div><div>Actually i did all those exercise before.</div><div> </div><div>First i ask telco to route call flow to 6 E1s only. But the same scenario is there.</div><div> </div><div>Then i cut down 2 more E1s, currently only 4 E1s running but the same scenario is there. </div>
<div> </div><div>Also i m using ulaw codec only and there is no transcoding there. also no echo cancellation is there. </div><div> </div><div>And main thing is 8 E1s working on the server with the same configuration and with the same telco without any problem.<br>
<br>I cant understand what is the problem</div><div> </div><div class="gmail_quote">On Wed, Feb 15, 2012 at 1:05 PM, Krzysztof Drewicz <span dir="ltr"><<a href="mailto:krzysztofdrewicz@gmail.com">krzysztofdrewicz@gmail.com</a>></span> wrote:<br>

Try to change architecture - some redundant setup and more servers, split TDM hardware to more boxes, and it will work... <br>As simple as that. If you don't believe, cut down traffic to 4 E1, by not configuring second card in dahdi/system, then add one E1, wait day or two etc... you will measure how much your box could handle.<br>
In my experience: recently bought servers go with max 7-8 TDM connections and not a single one more. <br>Simply - when 'soft modems' were popular on market - noone tried to put 4 soft-modems in one box. It was designed to use main CPU for many functions. <br>
Now - you try just to put many 'soft' cards into one box - without any check up if this architecture it could handle that. <br>Even 'smart' ss7 cards from dialogic or synway or any other vendors have some limits with max cards per box...<br>
Maybe - 1st step should be optimize your dialplan? <br>
