<p><font face="Helvetica, Arial, sans-serif">I notice that
BLF-buttons on my IP-phone are greyed out and again active after
some time. This goes on and on...</font></p>
<p><font face="Helvetica, Arial, sans-serif">When looking at

</font></p>
<p><font face="Helvetica, Arial, sans-serif">The BLF-buttons turn on
again after a new SIP SUBSCRIBE from my IP-phone. This SUBSCRIBE
happens every 120 seconds.</font></p>
<p><font face="Helvetica, Arial, sans-serif">They fade out after
about 85 seconds. Then after 35 seconds they come back up.<br>
</font></p>
<font face="Helvetica, Arial, sans-serif"><br>
In sip.conf I have the following settings :<br>
maxexpiry=100<br>
minexpiry=60<br>
defaultexpiry=100<br>
<br>
But that does not seem to change much. Except for SIP REGISTER's :
they now happen every 50 seconds (yes, 50) in stead of every 120
seconds.<br>
<br>
<br>
Can anyone help me to find the right timer to tune so I can have
stable BLF buttons ?<br>
<br>
<br>
<br>
Thanks.<br>
