AstLinux v0.7.6<br>Asterisk v1.4.39.1<br><br>I have found that in some recent version of Asterisk v1.4, NVFaxDetect has started to cause segfaults on my system. I am using the following code in extensions.conf:<br><blockquote style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;" class="gmail_quote">

exten => fax,1,Hangup<br></blockquote><br>[incoming] is my IAX2 trunk from my VoIP provider. Faxes used to work in the manner, but on some recent upgrade they started to produce the following errors in /var/log/messages:<br>
<blockquote style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;" class="gmail_quote">Feb 21 21:24:51 pbx <a href="http://user.info">user.info</a> kernel: asterisk[2457]: segfault at 8 ip 400a5625 sp 9d5fb46c error 4 in <a href="http://libuClibc-0.9.28.so">libuClibc-0.9.28.so</a>[4006e000+44000]<br>
</blockquote><div><br>My questions are the following:<br><ol><li>Has anyone else seen similar problems with NVFaxDetect?</li><li>Can anyone offer any insight/explanation?</li><li>Is it true that Digium is sidelineing IAX2 and only focusing on SIP? Should I be looking to migrate to SIP trunks instead?</li>
