<div dir="ltr">Thanks Brian, this makes a lot of sense.

Should 0 be handled? If so, is this an FS bug?</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jun 22, 2015 at 10:31 AM, Brian West <span dir="ltr"><<a href="mailto:brian@freeswitch.org" target="_blank">brian@freeswitch.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">See the logs with the offer and look at the codec parsing, without this its really hard to tell what is going on, it could be an issue in chrome.
