Can you be more specific about your Asterisk version? 10.xx.yy ?<br>
<br>
Sounds like some sort of resource leak.<br>

&gt; Hi,<br>
&gt;<br>
&gt; I configured Asterisk 10 for inbound fax, for couple of weeks I didn&#39;t see<br>
&gt; any issues until today. The setup  I configured for inbound fax is quite<br>
&gt; simple i.e. Cisco Voice GW sends the fax calls to Asterisk using T.38<br>
&gt; protocol and later Asterisk stores/forwards the fax to specific end user.<br>
&gt;<br>
&gt; The configuration I made in sip.conf for enabling T38 is listed below;<br>
&gt;<br>
&gt; t38pt_udptl = yes,fec,maxdatagram=400<br>
&gt; faxdetect = t38<br>
&gt;<br>
&gt; And in udptl.conf, I just uncommented &#39;use_even_ports = yes<br>
&gt; ;&#39; and rest of it set as default.<br>
&gt;<br>
&gt;<br>
&gt; Here is the error I&#39;m usually seeing in Asterisk side;<br>
&gt;<br>
&gt; [Jan 15 14:13:28] NOTICE[20514] udptl.c: UDPTL (SIP/10.3.22.6-00000ad6):<br>
&gt; Transmission error to <a href="http://10.3.22.6:18428" target="_blank">10.3.22.6:18428</a>: Resource temporarily unavailable<br>
&gt;<br>
&gt; If this notice comes, it occurs repeatedly unless I need to restart the<br>
&gt; asterisk service. For some reason it also effect the V-GW.<br>
&gt;<br>
&gt; Please advise what is the reason that I&#39;m getting this message and how can<br>
&gt; I avoid it?<br>
&gt;<br>
&gt;<br>
