Hello all,
<div>I’ve been reviewing a bunch of pcaps today during interop with a new ULC and I noticed that our FreeSWITCH instances send an Expires header in the INVITE that wasn’t present before the challenge.</div>
<div><br>
</div>
<div>I’ve got <param name="enable-timer" value="false”/> set in the profile, am I missing something?</div>
<div><br>
</div>
<div>Thanks!</div>
