Hardware Conferencing in CME
The following provides a guideline to enabling basic hardware conferencing in CME. There are additional options that can be tweaked, however the following is enough to get you off the ground. This will create the DSP farm and associate to the CME device for usage. Then, you'll need to create the ephone-dn's for meet-me and ad hoc conferencing. In the example below, a single ad hoc conference is configured for illustrative purposes.
- Prepare the DSP farm and services on the voice-card
- Configure SCCP parameters for the related application (in this instance, conferencing)
- Create the SCCP group and define the associate parameters, such as registration ID
- Create the dspfarm profile group for conferencing
- Enable the Skinny Client Control Protocol (SCCP)
- Under telephony-service associate the dspfarm profile, and enable hardware conferencing
- Configure meet-me and/or ad hoc conference ephone-dn's
