[cisco-voip] 7936 DHCP issue

[Voll, Scott]

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.

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? 

Thanks
