Create Meetme conference on Cisco CME

Create a meetme conference on CME is quite similar to ad-hoc conference in terms of configuration, here is an example how to create a Meetme conference on CME:

1. Create DSP Farm Porfile
sccp local GigabitEthernet0/0
sccp ccm 1.1.1.1 identifier 1 priority 1 version 7.0
sccp
!
sccp ccm group 1
associate ccm 1 priority 1
associate profile 1 register CFB
!
dspfarm profile 1 conference
codec g711ulaw
codec g711alaw
codec g729ar8
codec g729abr8
codec g729r8
codec g729br8
maximum sessions 2
associate application SCCP

2. Config telephony service to use hardware conference and associate it with the DSP Farm
telephony-service
sdspfarm units 1
sdspfarm tag 1 CFB
no privacy
conference hardware
no auto-reg-ephone
max-ephones 20
max-dn 20
ip source-address 1.1.1.1 port 2000
cnf-file location flash:
max-conferences 8 gain -6
transfer-system full-consult

3. Create ephone template that has the meetme softkey in seized state
ephone-template  1
softkeys seized  Redial Endcall Cfwdall Pickup Gpickup Callback Meetme

4. Create meetme conference ephone-dn
ephone-dn  10  octo-line
number 1234 no-reg primary
conference meetme
no huntstop

Conferencing Resources

A very usual question from people is, how many conference can I have, and how many parties can join a conference. Let me summarize below:

For Single-mode conference (G.711)
- PVDM - maximum 6 parties per conference
- ISR/PVDM2 - maximum 8 parties per conference
- WS-X6608 - maximum 16 parties per conference
- IPVMS - maximum 48 parties per conference
- CMM/ACT - maximum 64 parties per conference

For PVDM2, max 8 parties are allowed per conference, and 8 conferences are allowed per DSP. For using IPVMS in CUCM, maximum 48 parties are allowed per conference.

These are all G.711 values.

For example, if I have a PVDM2-16 = 2 DSPs = 2 x 8 conferences = max 16 conferences x 8 participants = 128 conference parties.

Max no. of conference per domain is 50 with 400 participants because of HW / IO limitation.

For mixed-mode conference (G.711 + G.729a)
- 2 conferences per DSP and 8 participants per conference.
