Hi

That bit of your config tells nothing; except that you have it configured to route calls to another PBX.

Which phones are you conferencing in, and from where?

What's the rest of your config?

I try conferencing from Cisco to Avaya.

I want to use ad hoc conference (software based) because Connection to site (conference problem) using SIP and I am using PVDM2-48.

Hi,

From your config, its obvoius that you have not configured conferencing. Below is a sample config of what you need to enable conferencing on your CCME router.

sccp ccm 10.10.0.1 identifier 1 version 7.0.............tell sccp what the ip address of your ccme router is (yours may be diff from 10.10.0.1)

dspfarm profile 1 conference status is shudown. When  I try to no shut, it asked

"Please configure the maximum sessions for this profile and retry"

CME(config-dspfarm-profile)#maximum sessions ?

  <0-0>  Number of sessions assigned to this profile

I can't enter for maximum sessions.

Hi, what that means is that you do not have enough DSP resources. You can either add more PVDM or reduce the number of voice channels you have provisioned for the circuit. You can also reduce the codec types on the dspfarm profile to only the ones you want or need.

Can you post a show diag so we can see what DSP/VICs you have?

Try removing G729r8 from the conference config, leaving the other g729 variants.

For sh diag, please see attached.

I removed G729r8 from the conference config, but still "can not complete conference"

I'am using PVDM2-48. From cisco documentation, it said that PVDM2-48 it's not supported for SCCP Hardware based. So I try to configure using SIP software based (SIP: Configuring Conferencing Options on a Phone). Am I wrong using SIP software based?

Thanks..

how to read that I have / do not have enough DSP resources?

Hi everyone,

I have the same problem,

but when I've removed the "conference hardware" in the telephony service.

Everything works fine. Try to do it.

Now this is my question :

When we shall use the command "conference hardware" and whe we should not use it?

Best regards,

Antra

Hello,

I have writen the "conference hardware" under telephony-services  and problem was solved.

Thanks iantra123

No conference hardware and all of a sudden everything is working like a charm!!

Awesome. Thanx. Removing the "conference hardware" worked for me as well.

Thanks iantra123, I had this issue too, but I've did that you said and was resolved then. A company mate did an upgrade in a CME "CISCO2911/K9" chassis to version 8.6 and IOS 15.1(4)M7 (I don't know what version have before); after this upgrading conference stop working, but removing "CONFERENCE HARDWARE" was resolved.

 

Thanks a lot guy.
