6.7.6.2 Configuring H.248 Protocol and Profiles
A Media Gateway (MG) communicates with a group of MGCs through a MG link. Both the MG and
MGC group form an H.248 association.
Once you have completed the steps in 6.7.6.1 Setting Up MGCs and MGC Groups, page 6-79, perform
the following steps to configure H.248 protocol and profiles:
Table 6-45 Field Descriptions for the VXSM Create MGC Groups Window
Field Name Description
MGC Grp Index Unique index value to identify the particular MGC group. The range is 1-12.
MGC Index Unique index value to identify each MGC (call agent) that communicates with
the media gateway. The range is 1-4.
Preference
Preference value of the IP address for the specific MGC (call agent). If the
value is lower, the preference of the IP address is higher. For example, the
value 1 has a higher preference than the value 2. If several IP addresses have
the same preference value, the media gateway selects them one at a time. The
range is from 1-12. The default value is 1.
UDP Port
Value to represent the UDP port of the MGC in the MGC group. A value of 0
means that no UDP port is specified. Therefore, the UDP port that is already
in the protocol table is used. The range is 1024-65535.
