<div class="PlainText">> Do we even WANT an idle timer?<br>
<br>
I posted my concerns already in <<a href="http://gerrit.asterisk.org/6807">http://gerrit.asterisk.org/6807</a>>: I have a device which crashes when it receives such a keepalive. I could live with a timer when Asterisk is not the registrar but registered somewhere
else. But I do not _need_ that either.<br>
