<p>Hi there...</p>
<p><br>
</p>
<p>Trying to get the BLFs working... Not much luck</p>
<p><br>
</p>
<p>Registration works and device to device calls work but the BLFs
dont....<br>
</p>
<p><br>
</p>
<p>Does anyone have a basic config where the BLFs work and calls
work that I can try?<br>
</p>
<p><br>
</p>
<p>If not, can someone point me in the right direction?<br>
</p>
<p><br>
</p>
<p><br>
</p>
<p>I get LOTS of these types of NOTIFYs but never one with a body...</p>
