Configuring Meet-Me Conference in Cisco CME
Cisco supports two types of conferences. There is the ad-hoc
conference which can support upto 3 participants and there is the Meet-me
conference which is basically the center of this post.
Meet-me is supported in Cisco ios routers running CALL Manager
Express. It is basically a conference bridge that participants call in and hold
a conference. It is supported by
hardware resources on the router. For ISR G2 routers we have PVDM3 with DSP chips
on them, this support audio and video conferencing.
Below is a sample config required to support Meet-me conference
upto 4 simultaneous meet-me conferences
with 8 participants each in a Cisco 2951 router running CME 9.0

How it works
The initiator of the conference has to be physically present
in the location. He/she presses the ‘New call’ softkey and then the ‘Meet-me’
softkey. Followed by the meet-me number, in this case it can be either
200/201/202 or 203. The call goes through and a conference is initiated. Other
participants then dial 200/1/2/3 directly without pressing ‘Meet-me’ since the
conference is already started.
The ephone-template config determines where the ‘Meet-me’
softkey is.
External participants will have to dial the full E.164
number to join the conference. In this case : +254204242200 .
A tone is played each time a person joins or leaves the
conference. The tone is specified under the ‘voice class custom cp-tone…’
config
For some companies, it is required that participants have a
PIN to authorize them enter the meet-me conference. To enable this, you will
upload a tcl script in the router. The script prompts callers for a PIN and
upon successful authentication the callers join the meet me conference.
Additional configs will be required to enable this, will
update as soon as I am done with the lab.
