No Conference Bridge Error on MeetMe

[Dmitry Vysotskiy]

Hey all,

I am trying to configure Hardware based conferencing on a Cisco 2811 ISR which has a PVDM-16 and PVDM-32 installed. I have configured SCCP and the conference profile in the DSPFARM and have entered 'No Shut' on the profile, watched the debugs as the resources get assigned however the conference bridge is still not fully up?? it's current state is: RESOURCE_ALLOCATED however the next line says: Application: SCCP Status: Not Associated?

I have entered the commands to associate the profile to SCCP so im not sure where the problem lies?

This router is running UCME 3.1 and I am configuring through the CLI.

Voice Configuration is below ( i have removed non essential config out):

voice class codec 1

codec preference 1 g729r8

codec preference 2 g729br8

codec preference 3 g711alaw

codec preference 4 g711ulaw

The problem I believe is with the status of the application...

#sh dspfarm all

Profile ID = 2, Service = CONFERENCING, Resource ID = 2

Profile Description :

Profile Service Mode : Non Secure

Profile Admin State : UP

Profile Operation State : RESOURCE ALLOCATED

Application : SCCP   Status : NOT ASSOCIATED

Resource Provider : FLEX_DSPRM   Status : UP

Number of Resource Configured : 2

Number of Resource Available : 2

Hope this is enough info for some help :-)

Hi Chris,

The Cisco Unified Communications Manager Express (CME) 4.1 Multi-party Conferencing Enhancement adds digital signal processor (DSP) based ad-hoc and meet-me conferencing capabilities to Cisco Unified CME system.

CME hardware conferencing requires 12.4(11)XJ or 12.4(15)T or later IOS and supports both Ad-Hoc and Meet-Me conferencing.

From this excellent doc from Tony @ Cisco

Cheers!

Once the router is upgraded to CME 4.1 or later, just change the following line in the configuration,

From:

sccp ccm 10.11.7.1 identifier 1 version 3.1

To:

sccp ccm 10.11.7.1 identifier 1 version 4.1
