Conference on CMM

Answered Question
Nov 13th, 2008

Hi everybody,

I configured a CMM module (WS-SVC-CMM-ACT) with CCM ver 4.1.3 as a conference bridge and it are properly registered in the CCM.

When I try to make a conference, I have the message “no conference bridge” on my phone.

The gigabit and fastethernet port are in same vlan on the switch, but only the gigabithe interface have a IP adresse on the CMM.

Any suggestions?

I have this problem too.

it's just a host address in your subnet, it knows the default gateway from the config

make sure the phone has the HW CFB in it's MRGL so it can access it. either device level or device pool MRGL

no, I only have my hardware CFB in my MRGL and my CFB it's registred.

you will need to configure an ip-address on the ACT Fast Ethernet interface, with a /32 mask

This interface is used for the RTP streams to the CFB

Hi Sascha,

thanks for your reply.

On the 6500, the gig and fast port are in same vlan. On my CMM card, my int g1/0 have ip When I try to configure the fast port with ip on the same vlan, I have this error "% overlaps with GigabitEthernet1/0" :)

did you configure ??

it needs to be a host address, so /32 mask

I do not understand. My gig interface have to communicate with default gateway ( How my fast interface can communicate with CCM if it's configure with /32?
