Late-to-Early Media Internetworking

The late-to-early media internetworking feature is supported for Session Initiation Protocol (SIP) calls. Early Media is the ability of two user agents to communicate before a call is actually established. Early Media can flow when the caller makes a media proposal on the initial call setup request and the callee responds to the offer before the call is connected. The SBC provides interoperability between SIP devices that do not provide SDP on their INVITEs and SIP devices that require SDP on INVITEs they receive. This occurs when

•An endpoint caller wants to negotiate media after the INVITE has been accepted (late media) and does not include an SDP offer on the initial INVITE

•The callee that expects an SDP offer on the initial INVITE, which it then answers with a 1XX response (early media).

The normal negotiation for media is for the caller to include an SDP offer on the initial INVITE and for the callee to accept with a 200 response. However,

•Late media is used by some endpoints, such as call agents that want to allow the callee to select the media used.

•Early media is used by some more recent endpoints that need to support media flow before the call is accepted, such as a pre-call announcement or in-band tones from a Call Hold server.

In order to interwork between a late media caller and an early media callee, the SBC sends an invite to the callee that includes an SDP offer of media. The SBC then sends appropriate messages between the caller and callee, depending on the responses from each.

The SBC supports this interworking on a per-adjacency basis. You can configure each adjacency to require late-to-early media interworking for calls made to that adjacency and/or for calls made from that adjacency.

Restrictions for Late-to-Early Media Internetworking Support

The restrictions for late-to-early media internetworking are:

•This feature applies only to SIP-to-SIP calls, it does not apply to SIP-to-H.323 interworking calls.

•This feature applies only to IPv4; you cannot use it with IPv6 addressing.

•If the caller refines the media chosen by the callee, this is sent back to the callee in a PRACK. However, if the callee attempts to refine the media again, the event is logged but it is not passed back to the caller.

•Because the SBC generates SDPs, any calls using this feature cannot use media bypass.

•The SBC only generates SDPs offering a single audio stream. If the caller and callee want to negotiate video, fax, or other media streams, they can renegotiate this after the call has been established.

•If the callee attempts to send early media either before or without sending a reliable 1XX INVITE, the SBC will drop that media; it will not reach the caller.

•The callee must not send unreliable 1XX INVITE responses because the caller would interpret them as an out-of-sequence SDP offer. For late-to-early interworking calls, the SBC sets 100rel as mandatory in order to forbid the callee from sending unreliable responses only if the caller side supports 100rel.

•Late-to-early media interworking must not be used with the Gq IMS interface. This interface does not provide the SBC with the local media address necessary to create an SDP offer (and will likely result in calls with incorrect media paths).
