No more than 8 participants on the meet me conference

[david.camus]

Hi, 

I have a meet me conference configured on my Cisco 2901 as:

telephony-service
 sdspfarm conference mute-on 111 mute-off 222
 sdspfarm units 1
 sdspfarm tag 1 MEETME_CFB
 conference hardware
 max-ephones 16
 max-dn 16
 ip source-address 10.100.36.101 port 2000
 max-conferences 8 gain -6
 transfer-system full-consult
!
!
ephone-dn  1  octo-line
 number 1111
 conference meetme unlocked
!

But impossible to reach more than 8 participants. When the ninth try to enter the conference, he get a "busy call".

When I do a "show ephone-dn summary", I can see:

PORT     CH  DN STATE     MWI_STATE    CODEC    VAD VTSP STATE            VPM STATE

Any help would be great.
Thanks.

With octo-line directory numbers, only one directory number is required for an 8-party meet-me or ad hoc conference. Up to eight select and join instances are supported.

Hi Jaime,

Thank you for your answer. Does it mean that I can't reach 16 participants with octo-line directory numbers ?

Thank you again.

[david.camus]

I realize I miss end-part of the configuration:

!
telephony-service
sdspfarm conference mute-on 111 mute-off 222
sdspfarm units 1
sdspfarm tag 1 MEETME_CFB
conference hardware
max-ephones 16
max-dn 16
ip source-address 10.100.36.101 port 2000
max-conferences 8 gain -6
transfer-system full-consult
!
!
ephone-dn  1  octo-line
number 1111
conference meetme unlocked
!
!
ephone-dn  2  octo-line
number 1111
conference meetme unlocked
preference 1
!

would it work with two octo-line ephone-dn to reach 16 participants ?

Thank you very much for your help.

What does the dspfarm confg looks like?

[david.camus]

Here the dspfarm profile:

dspfarm profile 1 conference  
 codec g711ulaw
 codec g711alaw
 codec g729ar8
 codec g729abr8
 codec g729r8
 codec g729br8
 maximum conference-participants 16
 maximum sessions 1
 conference-join custom-cptone jointone
 conference-leave custom-cptone leavetone
 associate application SCCP
!

I found the solution: need to configure "no huntstop" in the ephone-dn configuration !

[david.camus]

Ok well, I found solution to reach 16 participants, but the weird thing is that my Cisco just "eject" some random calls sometimes.

Without doing anything, after 2 or 3 minutes I loose a call (15/16)...

Capacity of the DSP maybe?...
