Gateway Configuration Settings
Use Trusted Relay Point From the drop-down list box, enable or disable whether Cisco Unified
Communications Manager inserts a trusted relay point (TRP) device
with this media endpoint. Choose one of the following values:
• Default—If you choose this value, the device uses the Use Trusted
Relay Point setting from the common device configuration with
which this device associates.
• Off—Choose this value to disable the use of a TRP with this
device. This setting overrides the Use Trusted Relay Point setting
in the common device configuration with which this device
associates.
• On—Choose this value to enable the use of a TRP with this device.
This setting overrides the Use Trusted Relay Point setting in the
common device configuration with which this device associates.
A Trusted Relay Point (TRP) device designates an MTP or transcoder
device that is labeled as Trusted Relay Point.
Cisco Unified Communications Manager places the TRP closest to the
associated endpoint device if more than one resource is needed for the
endpoint (for example, a transcoder or RSVPAgent).
If both TRP and MTP are required for the endpoint, TRP gets used as
the required MTP. See the
“TRP Insertion in Cisco Unified
Communications Manager” in the Cisco Unified Communications
Manager System Guide for details of call behavior.
If both TRP and RSVPAgent are needed for the endpoint, Cisco Unified
Communications Manager first tries to find an RSVPAgent that can
also be used as a TRP.
If both TRP and transcoder are needed for the endpoint, Cisco Unified
Communications Manager first tries to find a transcoder that is also
designated as a TRP.
Refer to the “Trusted Relay Point” section and its subtopics in the
“Media Resource Management” chapter of the Cisco Unified
Communications Manager System Guide for a complete discussion of
network virtualization and trusted relay points.
Signaling Port This field applies only to H.323 devices. The value designates the
H.225 signaling port that this device uses.
Default value specifies 1720. Valid values range from 1 to 65535.
Media Termination Point
Required
If you want a Media Termination Point to implement features that
H.323 does not support (such as hold and transfer), check the check
box.
Use this check box only for H.323 clients and H.323 devices that do not
support the H.245 Empty Capabilities Set message.
If you check this check box to require an MTP and this device becomes
the endpoint of a video call, the call will be audio only.
