<DIV><SPAN class=332292111-11122008>Hello</SPAN></DIV>
<DIV><SPAN class=332292111-11122008></SPAN> </DIV>
<DIV><SPAN class=332292111-11122008>Looking for some help with a rather odd
problem. We have Asterisk 1.4.10 running on a Linux box, within our
Windows domain. Our Domain Controller is a Windows 2003
server, providing the normal Windows domain functions, such as DHCP and
DNS.</SPAN></DIV>
<DIV><SPAN class=332292111-11122008></SPAN> </DIV>
<DIV><SPAN class=332292111-11122008>When we lose either our Domain Controller
(for a reboot/maintenance) or external ADSL access, Asterisk drops all SIP
registrations - even internal SIP calls within the building no longer
function.</SPAN></DIV>
<DIV><SPAN class=332292111-11122008></SPAN> </DIV>
<DIV><SPAN class=332292111-11122008>All of our SIP clients are assigned static
IP addresses, and our incoming lines are via a Zaptel card using (currently)
analog lines from our national telco. When the SIP registrations drop,
Asterisk will still answer incoming calls via the Zap channels, but can't
forward them anywhere.</SPAN></DIV>
<DIV><SPAN class=332292111-11122008></SPAN> </DIV>
<DIV><SPAN class=332292111-11122008>What is most confusing is a recent issue
when our ADSL connections were all offline, and despite everything internal to
the network working perfectly, all of the SIP phones stopped working and left us
without phones for 4 hours.</SPAN></DIV>
<DIV><SPAN class=332292111-11122008></SPAN> </DIV>
<DIV><SPAN class=332292111-11122008>I'm suspecting that these two issues (losing
connectivity when DC is unavailable and losing connectivity when ADSL drops) are
related, but I can't figure out how? I'm sure I'm missing something simple
in the config, but I've been tinkering with this issue since we were using
Asterisk 1.2 and I've still not resolved it.</SPAN></DIV>
<DIV><SPAN class=332292111-11122008></SPAN> </DIV>
<DIV><SPAN class=332292111-11122008>Any help or comments would be
appreciated...</SPAN></DIV>
<DIV><SPAN class=332292111-11122008></SPAN> </DIV>
<DIV><SPAN class=332292111-11122008>Thanks in advance</SPAN></DIV>
