In an ad hoc conference, a conference controller can add participants to a conference. In a Meet-Me conference, the conference controller provides a bridge or directory number for participants to dial.

CIPT1 v MOH Server Capabilities and Capacity Maximum number of MOH sessions per platform: –Cisco MCS 7815/25: 250 MOH sessions –Cisco MCS 7835/45: 500 MOH sessions 51 audio sources per cluster (50 files and one live/fixed audio source via a sound card). For unicast MOH, each device on hold requires a separate MOH stream. For multicast MOH, only a single MOH stream is required for each configured codec type. Multicast MOH can provide a considerable savings in server resources.

© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v MOH Audio Sources Recommended format for audio source files specifies the following: –16-bit PCM.wav file, stereo or mono –Sample rates of 48 kHz, 32 kHz, 16 kHz, or 8 kHz Most standard.wav files serve as valid input audio source files, including the following file types: –16-bit PCM (stereo/mono) –8-bit CCITT a-law or mu-law (stereo/mono) Administrator imports an audio source file into the Cisco Unified CallManager cluster. The file must be imported to MOH server in each cluster prior to assigning an audio source number to the audio source file. MOH server uses the local audio source files.

© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v MOH Configuration Tasks 1. Configure MOH server. 2. Add and configure audio source files. 3. Set MOH service-wide parameters. 4.Optionally, configure fixed audio source. 5. Assign audio source IDs.

© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v Summary Media resources provide services, such as transcoding, conferencing, MOH, and media termination, which are activated on the Cisco Unified CallManager. Conference bridge resources are software or hardware solutions that allow ad hoc and Meet-Me conferences. MTP resources provide supplementary services to H.323 endpoints that do not support the H.323v2 OpenLogicalChannel and CloseLogicalChannel request features. Annuciator resources play prerecorded announcements and tones.

© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v Summary (Cont.) Transcoder resources convert an output stream from one compression type to another to allow devices using different codecs to communicate. MOH resources provide users on hold with music from a streaming source. There are two types of holduser hold and network holdwhich are configured in Cisco Unified CallManager. Media Resource Groups and Media Resource Group Lists define logical groupings of media servers. The Media Resource Management controls and manages the media resources within a Cisco Unified CallManager cluster, allowing all Cisco Unified CallManager nodes to share these resources.
