the confrence should be intiated from inside and make sure u have enough DSP confrence resources assigned to the device pool through MGRL

if u use adhoc or meetme

Re: conference with 2 outside caller (from PSTN)???

I'm using CUCM 6.1

My Router gateway is 3825 with 1 E1 card, PVDM-64. How do I allocated DSP for conference?

I tried to configure hardware conference bridge on CUCM, and configure conference bridge in the router as follow:

sccp ccm 192.168.28.10 identifier 1 version 5.0.1

!

sccp ccm group 1

bind interface GigabitEthernet0/1

associate ccm 1 priority 1

associate profile 2 register CFB_12345

!

dspfarm profile 1 conference

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

codec g729br8

maximum sessions 2

associate application SCCP

But the conference bridge did not register with CUCM :( I dont know if I did any thing wrong? Plz help

Thankss

Re: conference with 2 outside caller (from PSTN)???

Prior to actual media resource configuration, the DSPs need to be enabled for DSP farm usage.

The dps services dspfarm command allocates the DSPs to the DSP farm, and the dspfarm

command enables the farm

for example

voice-card 0

dsp services dspfarm

sccp local GigabitEthernet0/1

sccp ccm 192.168.28.10 identifier 1

priority 1 version 5.0.1

sccp (this enable sccp prosses)

!

sccp ccm group 1

bind interface GigabitEthernet0/1

associate ccm 1 priority 1

associate profile 1 register CFB_12345

on CCM creat a conf brig (hardware ) and the name should look like (CFB_12345) exactly the same should be in the router and cucm

good luck

Re: conference with 2 outside caller (from PSTN)???

thank you very much, now the conference bridge registered with CCM. But the conference still not success.

I notified the command

GW_E1(config)#dsp confbridge maximum sessions ?

<0-0> Specify the maximum conferencing sessions value

Is it mean there is no DSP resource available to conference?

Plz help
