Media Termination Point Configuration
A Media Termination Point software device allows Cisco Unified Communications Manager to relay
calls that are routed through SIP or H.323 endpoints or gateways. You can allocate a media termination
point device because of DTMF or RSVP requirements. When a media termination point is allocated for
RSVP, you can insert it between any type of endpoint device, including SIP or H.323 devices.
Media termination point, a Cisco software application, installs on a server during the software
installation process. You must activate and start the Cisco IP Voice Media Streaming App service on the
server on which you configure the media termination point device. For information on activating and
starting services, refer to the Cisco Unified Serviceability Administration Guide.
Each media termination point device that is defined in the database registers with the Media Resource
Manager (MRM). The MRM keeps track of the total available media termination point devices in the
system and of which devices have available resources.
During resource reservation, the MRM determines the number of resources and identifies the media
resource type (in this case, the media termination point) and the location of the registered media
termination point device. The MRM updates its share resource table with the registration information
and propagates the registered information to the other Cisco Unified Communications Managers within
the cluster.
The media termination point and transcoder can register with the same Cisco Unified Communications
Manager. See the
“Transcoder Configuration” section on page 78-1 for more information.
Each media termination point receives a list of Cisco Unified Communications Managers, in priority
order, to which it should attempt to register. Each media termination point can register with only one
Cisco Unified Communications Manager at a time.
Note Depending on the capabilities of the SIP endpoint, Cisco Unified Communications Manager may require
an RFC 2833 DTMF-compliant media termination point device to make SIP calls. For RSVP calls, the
Media Resource Group List (MRGL) that is associated with the endpoint device needs to include the
media termination point devices that support RSVP.
