<div dir="ltr"><div><div><div><div>I have my own extensive unpublished patch for Asterisk 1.8 that fixes lots of SS7/ISUP issues for me.<br></div>I tried Asterisk 11 with unpatched sources and found lots of issues again. I couldn't even get a stable environment with just all trunks aligned.<br></div>So I'm not surprised you're having problems.<br></div>No, my patch isn't available, not it will for free. Most problems have been reported to this list before, and haven't been addressed in the 3 years passed since I reported them.<br></div>So I don't advise anybody to use either ss7 solutions, you will have serious problems. The libss7 development process is unable to deliver a serious ss7 solution that will work properly.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Apr 19, 2016 at 2:09 PM, Goke
