The examples in this document are from a gateway that uses a High Density Voice Network Module (NM-HDV) for Transcoding and Conferencing resources. The NM-HDV module is supported on the Cisco 2600XM, Cisco 2691, Cisco 3725, Cisco 3745, Cisco 3660, Cisco 3640, Cisco 3620, Cisco 2600, and Cisco VG200 gateways. Note: This document assumes that you have configured Device Pools, Regions, Media Resource Groups, and Media Resource Lists in Cisco CallManager. The focus of this document is on the IOS Gateway DSP Farm configuration and how to configure Transcoding and Conferencing resources in Cisco CallManager. Prerequisites Requirements Readers of this document need to have knowledge of these topics: Cisco CallManager DSP Farms Transcoding and Conferencing

Components Used The information in this document is based on these software and hardware versions: Cisco CallManager version 4.0(1) Cisco IOS Software Release 12.2(15)T13 IP Plus Cisco 2651 Gateway NM-HDV with two Packet Voice DSP Module (PVDM) DSP Single In-line Memory Modules (SIMMS) The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Conventions Refer to the Cisco Technical Tips Conventions for more information on document conventions. Plan for the Number of DSPs Installed The NM-HDV Farm module ships with two SIMMS and is able to handle three additional SIMMS. Each SIMM contains three DSPs. Each DSP supports four Transcoding sessions or one Conference Bridge. Four Transcoding sessions are supported for g729-g711. If you use the Global System for Mobile communication (GSM), then the DSPs can handle three Transcoding sessions. Therefore, the maximum number of Transcoding sessions supported by a five-SIMM configuration is sixty Transcoding sessions. The maximum number of conference calls supported by a five-SIMM configuration is fifteen. The Conference Bridges and Transcoder sessions configured count against the cumulative total and cannot exceed the limit of what is
