[kidatsuda]

When i try initiate conference with 3 or 4 paricipants, third and fourth participants listen silent if sccp phone or listen music if sip phone

#show dspfarm all

SLOT   DSP VERSION  STATUS CHNL USE   TYPE    RSC_ID BRIDGE_ID PKTS_TXED PKTS_RXED

I think if  i increase maximum participants in conference profile this solve my problem

When i try change  profile i have message  profile oper state is up in progress already

#dspfarm profile 1 conference

(config-dspfarm-profile)#maximum conference-participants 8

(config-dspfarm-profile)#no shutdown

 profile oper state is up in progress already

How can i change participants in profile?

Thanks for help

I do not see you shutting down the dspfarm profile , shutdown the dspfarm profile first, make changes and do a no shut.

Thanks for your answer

I perform

#dspfarm profile 1 conference

(config-dspfarm-profile)#shutdown

Disabling profile will disconnect active CONFERENCING calls,
do you want to continue ? [yes/no]yes

(config-dspfarm-profile)#maximum conference-participants 8
(config-dspfarm-profile)#no shutdown

(config-dspfarm-profile)#end

#show dspfarm all

Can you share the 'show run' and 'show sccp' from the CME. Also 'show sccp conn' for an active conference call.

Hi,

Conferencing Oper State: ACTIVE_IN_PROGRESS - Cause Code: TCP_CONN_ERROR

In your config, you have

 associate profile 1 register confprof1

and

 sdspfarm tag 1 confdsp1

Change the "sdspfarm tag 1 confdsp1" to  "sdspfarm tag 1 confprof1" and do a no sccp / sccp

Let us know if that fixes the issue.

sorry i newbie in cisco

me need perform:

#telephony-service

#no sccp

#sdspfarm tag 1 confprof1

#sccp

#end

I understand you correctly?

[Manish Gogna · Accepted solution]

Hi,

You need to do "no sdspfarm tag 1 confdsp1"

and

"sdspfarm tag 1 confprof1"

Then do "no sccp" followed by "sccp"
