CUCM uses SCCP to control media resources, such as conferencing resources, transcoding resources, media termination point (MTP)
resources, Music on Hold (MoH) resources, and annunciator resources. SCCP can also be used to control FXS ports on certain IOS
voice gateway platforms.
Call agent, device, and endpoint types that can communicate using SCCP include CUCM, CUCM Express, Cisco Unity (voicemail
ports), routers running SRST, VG200 (DSP-farm), VG224, VG248, ATA186, ATA188, Cisco IP phones, Cisco IP Communicator,
Tandberg and Sony video endpoints, Cisco 3800/3900 gateways, Cisco 2800/2900 gateways, Cisco 3700 gateways (DSP farm), Cisco
3640/3660 gateways (DSP farm), Cisco 2600/2600XM gateways (DSP farm), Cisco 1751/1760 (conferencing/transcoding), and WS-
X6608-T1/E1.
Four steps are involved in configuring CUCM-controlled media resources:
Step 1.
Enable DSP farm services.
Step 2.
Configure a DSP farm profile.
Step 3.
Configure SCCP.
Step 4.
Specify media resources in CUCM.
