User's Manual 17. Control Network
Version 6.8 253 Mediant 500 E-SBC
Parameter Description
a SIP Interface is 6060, you must configure the
BaseUDPPort parameter to any value greater than 6060.

The port must be different from ports configured for SIP
traffic (i.e., ports configured for SIP Interfaces). For
example, if the RTP port range is 6000 to 6999, the SIP
port can be less than 6000 or greater than 6999.
Number of Media Session Legs
CLI: session-leg
[CpMediaRealm_MediaSessionLeg]
Defines the number of media sessions associated with the
range of ports. This is the number of media sessions
available in the port range.
Port Range End
CLI: port-range-end
[CpMediaRealm_PortRangeEnd]
(Read-only field) Displays the ending port for the range of
media interface UDP ports. The device automatically
populates the parameter with a value, calculated by the
summation of the 'Port Range Start' parameter and 'Number
of Media Session Legs' parameter (multiplied by the port
spacing) minus 1:
start port + (sessions * port spacing) - 1
For example, a port starting at 6,000, 5 sessions and 10 port
spacing:
6,000 + (5 * 10) - 1 = 6,000 + (50) - 1 =
6,000 + 49 = 6,049
The device allocates the UDP ports for RTP, RTCP and T.38
in "jumps" (spacing) of 10 (default). For example, if the port
range starts at 6000 and the UDP port spacing is 10, the
available ports include 6000, 6010, 6020, 6030, and so on
(depending on number of media sessions).
For RTCP and T.38 traffic, the port offset from the RTP port
used for the voice session (channel) is one and two,
respectively. For example, if the voice session uses RTP port
6000, the RTCP port and T.38 port for the session is 6001
and 6002, respectively. However, you can configure the
device to use the same port for RTP and T.38 packets, by
setting the T38UseRTPPort parameter to 1.
Default Media Realm
CLI: is-default
[CpMediaRealm_IsDefault]
Defines the Media Realm as the default Media Realm. This
default Media Realm is used when no Media Realm is
configured for an IP Group or SRD for a specific call.

[0] No (default)

[1] Yes
Notes:

This parameter can be set to Yes for only one defined
Media Realm.

If the parameter is not configured, then the first Media
Realm in the table is used as default.

If the table is not configured, the default Media Realm
includes all the configured media interfaces.
QoE Profile
CLI: qoe-profile
[CpMediaRealm_QoeProfile]
Assigns a QoE Profile to the Media Realm. For configuring
QoE Profiles, see ''Configuring Quality of Experience
Profiles'' on page
240 .
BW Profile
CLI: bw-profile
[CpMediaRealm_BWProfile]
Assigns a Bandwidth Profile to the Media Realm. For
configuring Bandwidth Profiles, see ''Configuring Bandwidth
Profiles'' on page
