&gt;&gt;<br>
&gt;&gt; I&#39;ve found this interesting document<br>
&gt;&gt; <a href="http://www.sangoma.com/assets/docs/misc/2009_10_09_How_to_Reduce_Asterisk_System_Loads.pdf" target="_blank">http://www.sangoma.com/assets/docs/misc/2009_10_09_How_to_Reduce_Asterisk_System_Loads.pdf</a>.<br>

&gt;&gt;<br>
&gt;&gt; After having read it I&#39;ve tried to set chunk size to 40 for using<br>
&gt;&gt; sangoma + chan_ss7. But it doesn&#39;t work. Chan_ss7 seems not to be able<br>
&gt;&gt; able to setup link on mtp level. I got this permanently:<br>
&gt;&gt; ...<br>
&gt;&gt;<br>
&gt;&gt; Has someone already struggled with the same problem? Is there any patch<br>
&gt;&gt; for this?<br>
&gt;&gt;<br>
&gt;<br>
&gt; i have the same problem. no solution<br>
