Hi all,<div><br></div><div>Thanks for everyones feedback on this, there's a lot of really useful info and this will make life much easier when writing the docs.</div><div><br></div><div>I'm hoping to make a start on this within the next month (mod_xml_curl and mod_event_socket are first in my list).</div>
<div><br></div><div>Of course, others are more than welcome to contribute as well :)</div><div><br></div><div>Cal<br><br><div class="gmail_quote">On Thu, Jan 3, 2013 at 4:12 PM, peely <span dir="ltr"><<a href="mailto:freeswitch@peely.com" target="_blank">freeswitch@peely.com</a>></span> wrote:<br>

handling it. We've rarely had any issue with our end sending INVITEs to the<br>
wrong place or one / no way speech. connectile dysfunction does nothing<br>
more. The only switch we enable is one to enable the SIP options ping and to<br>
use sip-force-expires to reduce the time the endpoint re-registers for<br>
mobile devices.<br>
<br>
As with others on this thread, the ALG in most routers is the culprit, I've<br>
rarely experienced one which does anything beneficial, most screw up the<br>
headers.<br>
<br>
We also recommend that customers change the SIP port on their handsets to<br>
anything other than 5060, older BT routers especially seem to stop<br>
forwarding responses after a few minutes, again as they have a very basic<br>
ALG. Using port forwarding in the router is the only sure fire way of<br>
getting reliable SIP through to a handset, Draytek routers seem to be pretty<br>
flaky until you do this or use TCP / TLS.<br>
<br>
If the router stops forwarding packets because of a poor ALG implementation<br>
or other firewall rules, nothing FS can do will overcome this.<br>
