<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Sounds like a possible DNS issue. I had a
problem were I have a PIX and the Voice vlan could NOT get to the DNS server
and it did the same kind of idea. </span></font></p>

issue</span></font></p>

<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Conference phone gets plugged into a port on the first voice vlan and
gets an IP from the DHCP pool no problem. Customer moves to another switchport
(same switch) configured on one of the other voice vlans and it takes several
hours to pull a new IP. Customer is using a different voice vlan for each of
three floors. The 7936 has the latest firmware but also experienced the problem
on previous version. Also, a new conf phone has been tried with same results.
Moving 7940's and 7960's between floors works just fine. Last test was to
create reservations in each pool but apparently that didn't work. Anyone else
seen this behavior with the 7936? <br>
<br>
Thanks</span></font></p></span></div>
