Ribbon recommends using the Transparency Profile to configure transparency on the SBC Core for new deployments, as well as applying additional transparency configurations to existing deployments. Do not use IP Signaling Profile flags in these scenarios because the flags will be retired in upcoming releases.
Refer to the SBC SIP Transparency Implementation Guide for additional information.
Use this object to define the parameters associated with the Media features for this SIP trunk group.
The SBC 52x0 and SBC 7000 systems support creating IP Interface Groups containing sets of IP interfaces that are not "processor friendly" (i.e. carried on physical Ethernet ports served by separate processors). However, restrictions exist regarding the usage of such Interface Groups.
(This ability does not apply to the SBC 51x0 and SBC 5400 systems which have only two physical media ports. IP interfaces from the two physical ports may be configured within the same IP Interface Groups without restriction.)
For complete details, refer to Configuring IP Interface Groups and Interfaces.
On SBC main screen, go to Configuration > System Provisioning > Category: Trunk Provisioning > Trunk Group > Sip Trunk Group > Media. The Media window is displayed.
The Media can be checked for each Address Context, for each Zone, for each Sip Trunk Group created or for all the Address Contexts, Zones and Sip Trunk Groups created. Use the drop-down box to select the desired Address Context, Zone and Sip Trunk Group.
The Edit Media window is displayed.

The following fields are displayed:
Sip Trunk Group - Media parameters
Parameter | Description |
---|---|
| Specifies whether the SBCwill transpass media direction (Data Path Mode) received from a peer in the Offer SDP RTP IP.
|
| If enabled, attempt to set up a direct-media path so that media flows directly between endpoints in the same direct-media group.
|
Dtls Profile Name | Specifies the name of the Dtls Profile which would be attached to this Trunk Group. To create a Dtls Profile, refer to Security - Dtls Profile. |
| If enabled, attempt to set up a direct-media call for endpoints behind NAT.
|
| Enable flag on trunk groups facing AS to allow direct media using C-line trigger (e.g. media antitrombone).
Direct Media configuration ( |
| This identifies the direct media group to which this trunk group belongs. The value ranges from 0 to 655535 and the default value is 0. |
| Determines whether a SIP late media (reverse offer) INVITE should be converted to a forward offer on egress or else allowed to transparently pass through.
If you configure Packet Service Profile When
Set this flag at the Ingress leg of the Trunk Group. |
| This field indicates the default packet size in milliseconds. The value ranges from 10 to 150 and the default value is 150. |
| Indicates whether the SDP offer sent by SBC includes any direction attribute line defined by COMEDIA draft.
|
Tmr64K | Enable this flag to allow the transmission Medium Requirement Unrestricted 64kbit/s control for SIP-ISUP interworking.
|
| Name of the IP interface group for media. |
Media Ip Address | default = 0.0.0.0 Each trunk group can have a The |
| When enabled, incoming media packets which do not match the expected source IP address and UDP port are filtered out.
|
| The Media Address Type attribute determines the type of IP address used in the offer.
The The ice parameter is available only when |
| Enable flag to support media recording of RTP stream to an external recording device on this SIP trunk group.
|
| Enable this flag to control the selective relay of unknown SDP attributes at session level and attributes from core audio stream.
|
Msrp | Enables the MSRP payload relay over TCP connections that will be setup on a successful negotiation of MSRP SDP attributes. The options are:
|
Omr Allowed | The options are:
|
Omr Primary Realm | Use this parameter to choose which Address Context realm name to use as the primary realm for this SIP trunk group.
|
Advertise Audio Only | When enabled SBC sends only the main audio/image stream in the SDP offer. The options are:
|
Lync Share | This flag supports Lync/Desktop sharing application media streams. The options are:
