I cant connct more than 6 phones to conference on CUCM 7 with HW CFB

Hi,

I have problem with connecting more than 6 phones to conference. I'm using hardware conference bridge Cisco 2811 (see below).

When I want connect 7th phone to conference and I press "Conference" button after call was established, 7th phone is connected to conference but phone which I calling from was disconnected.

If you need any other things from configurration of router tell me.

You can see output from configuration during conference with 6 phones.

I think that problem is DSP SHARING, but I can't find article which tell me how to resolve it. I think that voice router don't know use channels from other DSP and it is using only 6 channels which is on one DSP (if you look below on 'sh dspfarm all' there is what I mean)

Thank for any help

My configuration:

CUCM: version 7.1.3

That's WAD:

Conferencing and Transcoding Features on the NM-HDV

Conferencing

Cisco Unified Communications Manager  meet-me and ad-hoc conferences with up to six participants each

Up to 15 six-party conferences on a  single NM-HDV

Participants using G.711 and G.729  codecs joined in a single conference; no additional transcoding  resources are needed to include the disparate codec types

Easy deployment of conference resources  in routers across the network, reducing WAN use and improving  voice-network performance
