dspfarm maximum sessions question

[steve.grosz]

Hi there

I am trying to get a handle on how the MeetMe works.  We have the following entry on our CME system

dspfarm profile 1 conference 

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

codec g729br8

maximum sessions 4

conference-join custom-cptone jointone

conference-leave custom-cptone leavetone

associate application SCCP

Does this mean that we can have 4 independant sessions of MeetMe at the same time?  As far as I know we just have 1 call in number, if it IS possible to handle 4 different conferences at the same time, how would I configure different call in numbers?

Or am I not understanding this correctly??

[Jaime Valencia]

Yes, that's 4 independent sessions

Hmmmmm, I can't view that document for some reason.......

Hi Steve,

You should be able to if you remove "/partner" from the URL.

Like Jaime rightfully pointed out, you can have 4 seperate meet-me conference numbers configured for the config you shared.

Harmit,

What URL are you referring to?

[Harmit Singh]

Steve, the one Jaime gave you which you said you couldnt open :-)

Gotcha!   Thanks

So here we have our config:

ephone-dn  110  dual-line

number 5555

name MeetMe

conference meetme

no huntstop

!

!

ephone-dn  111  dual-line

number 5555

name MeetMe

conference meetme

preference 1

no huntstop

!

ephone-dn  112  dual-line

number 5555

name MeetMe

conference meetme

preference 2

          no huntstop

ephone-dn  113  dual-line

number 5555

name MeetMe

preference 3

no huntstop

!

ephone-dn  114  dual-line

number 5555

name MeetMe

conference meetme

preference 4

no huntstop

!

ephone-dn  115  dual-line

number 5555

name MeetMe

conference meetme

preference 5

          no huntstop

!

ephone-dn  116  dual-line

number 5555

name MeetMe

conference meetme

preference 6

no huntstop

!

!

ephone-dn  117  dual-line

number 5555

name MeetMe

conference meetme

preference 7

The number is always the same, 5555, but if we can actually have different conference calls going at the same time, we only have the one external number..... its like 333-3155.......  if we can have 4 differenct conference calls going at the same time, how can I assign 3 new external phone numbers to the MeetMe system??

Steve,

If you only have 1 MeetMe number configured than you can only have 1 MeetMe conference regardless of how many conferences you have on the CME router configured. Also as a side note if you don't need to support all the codecs you have configured I would remove them and restrcuture your DSPFARM as it would allow you to have more participants in a conference. Example below:

Example 1:

The configuration below with 4 session would only allow 8 - 16 participants because you have G729 configured

dspfarm profile 1 conference 

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

codec g729br8

maximum sessions 4

conference-join custom-cptone jointone

conference-leave custom-cptone leavetone

associate application SCCP

Example 2:

The configuration below will allow (depending on the DSP you have) 4 sessions with 8 - 32 participants because only G711 is configured.

dspfarm profile 1 conference 

codec g711ulaw

codec g711alaw

maximum sessions 4

maximum conference-participants 32

conference-join custom-cptone jointone

conference-leave custom-cptone leavetone

associate application SCCP

Hope I didn't confuse you...

Ok I stand corrected I completely ignored the fact that you are running CME... So you can have mulitple conferences with one number as Jaime mentioned above.

Steve,
If you're not using G729 on your network than I would suggest using G711 on the DSPFARM. If you want to allow up to 32 participants on a conference make sure you put the "maximum conference-participants 32" command on the DSPFARM. Please note that the amount of conference participants you allow will affect the amount of conference session you can configure on the DSPFARM.

I checked the config on the router, and didn't see a reference to G729 anywhere but in the DSPFARM.......is there somewhere else I need to look for it to see if G729 is being used??

[yahsiel2004]

VoIP dial-peers are G729 by default so you might want to make sure that you set the codec to G711. Also if you have integrated any other applications with CME, verify that it doesn't require G729. If you configure the DSPFARM for G729 only the worste case scenerio would be that you would need to initiate a transcoder if a caller entering the conference is using G729.
