MGCP-CONFIG CONFIGURATION ELEMENTS A-M
Version S-C6.1.0 Oracle Communications Session Border Controller ACLI Reference Guide 181
Default 0.0.0.0
public-gw-port—Enter the port on media interface in the public realm. This field
value is the media gateway port that the Net-Net SBC uses to communicate with
the call agent or softswitch.
Default 2427
Values Min: 1025 / Max; 65535
second-public-gw-port—Enter the second UDP port on public-gw-address where
Net-Net SBC receives packets from the call agent or softswitch. Net-Net SBC can
receive messages from the call agent or softswitch on either the public-gw-port or
the second-public-gw-port.
Default 0
Values Min: 1025 / Max: 65535
alg-port—Enter the port used to send a packet from the network processor to the
host processor. Each mgcp-config must have a unique ALG port so the ALG
function can distinguish which mgcp-config element applies to packets sent up
from the network processor.
Default 2427
Values Min: 1025 /Max; 65535
mode—Set the MGCP-NAT mode. This field defines how endpoint names are
translated as MGCP flows traverse the Net-Net SBC. This is a required field.
Default LineUnit
Values • Host—A “unit” term is added to endpoint name on public side to
uniquely identify the gateway/host on the private side. The left-most
part of the private FQDN is used as the unit term (or unit name).
• LinePrefix—Divisor field value is used to compute a number to insert
into the localname part of the endpoint name. The number to be
inserted is the IP address modulo the divisor. This mode inserts this
number before the channel number. Example: aaln/1 becomes
aaln/1231. The IP address part is replaced by the public-gw-address.
• LineUnit—Divisor field value is used to compute a number to insert
into localname part of endpoint name. The number inserted is the IP
address modulo the divisor. This mode adds the unit-number term
defined in the conventions section of ftp://ftp.rfc-editor.org/in-
notes/rfc3435.txt (e.g., aaln/2 becomes aaln/123/2). The IP address part
is replaced by the public-gw-address (also defined in this element).
• FQDN—Dots are removed from the host portion of the private
endpoint. Example: the address aaln/[e-mail] on the private
(i.e., gateway) side would become aaln/abcxyzcom/[e-mail] on the
public (i.e., call agent) side.
• FQDN2—Dots are retained in the host portion of the private endpoint.
Example: the address aaln/[e-mail] on the private (i.e., gateway)
side would become aaln/abc.xyz.com/[e-mail] on the public (i.e., call
agent) side.
• OnlyHost—Endpoint name is not translated.
• None—Endpoint name is not translated.
