<DIV><SPAN class=109342415-07092006><FONT face=Arial size=2>I have a Polycom 501
connected to Asterisk 1.2.4 (and then connected to a VOIP provider, Unlimitel in
my case). My job requires me to attend conference calls regularly, and I
am usually there as a silent listener. Therefore, I mute my
phone.</FONT></SPAN></DIV>

<DIV><SPAN class=109342415-07092006><FONT face=Arial size=2>I`ve noticed that if
I mute my phone, after 10-15 of being muted, the line hangs up. I had the
same problem with my GXP-2000 before, so I dismissed the phone as being the
problem. If I unmute regularly (or the entire time), the line doesnt hang
up (until it reaches max timeout of course, which is much more than 15
minutes). So the problem is my phone is muted. I have observed that
about 6 times (out of 6 tries) in the last 4 months. It`s a reccuring
issue for sure.</FONT></SPAN></DIV>

<DIV><SPAN class=109342415-07092006><FONT face=Arial size=2>What I am left with
is Asterisk (or my VoIP provider) as the issue. Since I only have control
on my own Asterisk server, I thought I should start there. What setting
could cause this? I have a fairly fancy dialplan, but I havent changed anything
else than the diaplan. All system-wide Asterisk settings are default as
far as I know.</FONT></SPAN></DIV>
