Overview of SIP DMR Configuration

To configure SIP DMR:

1. Edit the SIP config element’s option field.

   The media-release=”<header-name>[;<header-param>]” option defines how the SIP distributed media release feature encodes IPv4 address and port information. If the media-release parameter is configured in the options field but no header is specified, the parameter value of P=Media-Release will be used. This parameter is optional and is not configured by default.

2. Enable SIP DMR for the entire realm by setting the realm config element’s msm release field to enabled.

   The media IPv4 address and port information is encoded into outgoing SIP messages and decoded from incoming SIP messages for all of the realms (in each realm-config element) with which the SIP distributed media release will be used.

   Note:

   You can also use the realm config element’s mm in network field to release the media back to a connected network that has multiple realms. This field is not specific SIP distributed media release and it is not required for the SIP DMR to work. However, if this field is set to enabled and the ingress and egress realms are part of the same network interface, it lets the Oracle® Enterprise Session Border Controller release the media.
