CME and conference with maximum sessions to 0

[jean-bruno.emonet]

Hello,

I configured a CME 2811 to establish conferences. When I want to add a phone on the conference I have : "cannot complete conference".

Here the harware inventory :

NAME: "2811 chassis", DESCR: "2811 chassis"
PID: CISCO2811         , VID: V02 , SN: FCZ100172DD

PID: PVDM2-8           , VID: V01 , SN: FOC11415G48

I configured the cme :

voice-card 0

 shutdown

telephony-service
 sdspfarm units 1
 sdspfarm transcode sessions 128
 sdspfarm tag 1 conference
 conference hardware

I can't no shut the profile conference because maximu session is not defined. But the maximum  is 0

CCME(config)#dspfarm profile 2 conference
CCME(config-dspfarm-profile)#maximum sessions ?
  <0-0>  Number of sessions assigned to this profile

Is the DSP allocated for other ressources ?

Apply below command under telephony-service and try once.

no conference hardware

Hi

yes , you have to increase your PVDM resources to get enough resources to do hardware conference . Your resources is used by Voice-cards 0/0 & 0/1.Can you disable transcode profie as the below:-

dspfarm profile 1 transcode
shu
no max sessions 1

dspfarm profile 2 conference
max sessions ?

Note: keep in your mind , no need for conference hardware if the conference will be between g711 participants "software Conference will be enough", if the conference will be done with other g729 Prticipant so in this time you will need conference hardware.

Thanks

There's no point in having him disable transcoding, it won't change a thing, he only has half DSP.

A HW CFB with PVDM2 requires the whole DSP for conferencing, unless you give up on using that half DSP for TDM termination and XCODER, and use it for a HW CFB, there's nothing to do here.

You need to buy more DSPs.

Hi

+5 for jamie ,i just asked him to disable transcoding because he didnot associate transcoding profile under sccp ccm group . Anyway so you have to purchase PVDM because you have to do hardware conference ..

That is a complete different topic from the one on this thread, open a new thread for this. And also mention what material have you reviewed.

Hello,

I disabled the transcode profile. Max session is still at 0-0.

I need to make conference with g729 codec.

Thanks.

Ok, so if i want to make conference in G729 (transcode needed so), I need to buy PVDM . Because i don't have enough resource for both conference/transcoding.

How can i calculate it?

Is that right?

Thanks.

JB

[Jaime Valencia]

Use the DSP calculator online, you'll need at least, another half DSP, or a full DSP, depending on how many conferences you want.
