<div dir="ltr">Alax you're correct, but not all sip device manufacturers really know the sip rfc etc, soft phones and phone manufacturers are better, but in my case its a SIP door bell, when there is only one sip server as is the case with most of these units that they are connected to a small business PBX like FreePBX it works, the problem starts when there is more than one server in the path, I spoke their tech support and its been 2 days and they still don't have a fix yet, so its nice to have a workaround for cases like these.</div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Feb 4, 2016 at 5:09 PM, Alex Balashov <span dir="ltr"><<a href="mailto:abalashov@evaristesys.com" target="_blank">abalashov@evaristesys.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On 02/04/2016 11:08 AM, Alex Balashov wrote:<br>

That's interesting. I had no idea OpenSIPS had a module specifically<br>
devoted to fixing bad SIP that really shouldn't be fixed. :-)<br>
