I am working on a client's network who are having problems with Ad-HOC
Conferenceing. They have a CMM module with the attached configuration.
They have assigned the ip address to
Intereface Gigabitethernet 1/0
ip address 10.160.252.30 255.255.254.0
and that makes perfect sense, but if you look down you will see the another
address on
Interface Gigabitethernet 3/0
10.160.252.31 255.255.255.255
The Gigabit Ethernet 1/0 address has been registered with the call manager.
I don't understand why there is a second address assigned to 3/0 interface
with 32 bit mask. Can I remove it without bringing the PSTN Connection
down? I believe that is the main reason Ad-Hoc conference is not working
since the hardware media resources are accessed from CMM Module. The
access-list has been configured on Voice-Server VLAN on 6500 switch to
protect the network, and the second address (configured on interface 3/0) is
not allowed. Access-list only allows 10.160.252.30 address, and that is
only known address Call Manager knows and should allow IP Phones to access
Media resources. Somehow IP Phones think that the address 10.160.252.31
is the address for Media resources which is bogus.
I turned on debugging on 6509, and tested 3 IP Phones for Ad-Hoc
Conference, and
saw the logging messages where request came from first IP Phone was denied
to access
10.160.252.31 address.
Can someone shed some light?
