– Listen Port: Enter the port number used to communication via this channel. The
combination of Listen Address and Listen Port must be unique across all channels
configured for the server. SIP channels support both UDP and TCP transport on the
configured port.
– External Listen Address and External Listen Port: Edit these fields to match the
public address of a load balancer associated with this channel. When the server selects
an interface or logical address to use for outbound network traffic, WebLogic SIP
Server examines the channel that was configured with the same primary Listen
Address; if the External Listen Address of this channel differs, the external address is
embedded into SIP message headers for further call traffic. See “Configuring Load
Balancer Addresses” on page 1-3.

11. Optionally click Show to display and edit advanced channel properties, such as connection
timeout values. Keep in mind the following restrictions and suggestions for advanced channel
properties:
– Outbound Enabled—This attribute cannot be unchecked, because all SIP and SIPS
channels can originate network connections.
– HTTP Enabled for This Protocol—This attribute cannot be selected for SIP and SIPS
channels, because WebLogic SIP Server does not support HTTP transport SIP
protocols.
– Maximum Message Size—This attribute specifies the maximum TCP message size
that the server allows on a connection from this channel. WebLogic SIP Server shuts
off any connection where the messages size exceeds the configured value. The default
size of 10,000,000 bytes is large. If you are concerned about preventing Denial Of
Service (DOS) attacks against the server, reduce this attribute to a value that is
compatible with your deployed services.

Configuring Custom Timeout, MTU, and Other Properties
SIP channels can be further configured using one or more custom channel properties. The custom
properties cannot be set using the Administration Console. Instead, you must use a text editor to
add the pro perties to a single, custom-property stanza in the channel configuration portion of
the config.xml file for the domain.
