The IOI simply identifies the networks on both sides of the session. This would only be the case if the originating network were different from the terminating network. Otherwise, the network is the same and there is no need for IOI. This header is used in conjunction with the P-CHARGING-FUNCTION-ADDRESS header, as well as the P-ACCESS-NETWORK header. Together these headers provide a fair amount of information that can be quite useful to SIP networks. As with all charging data, this header is only used within a trusted domain and is not sent outside of the home network. The exception to this rule is if the outside network has an agreement in place with the home network, in which case it is considered a trusted domain. Following is an example of this header:

In SIP networks, the initiation of a session can sometimes result in conversation being chopped off, especially when the session first begins. This is due to the very nature of how a session is established, and when the medium is actually cut-through. In the PSTN, the voice facility (trunk) is connected end to end in one direction to allow for tones (such as ringback) and digits (DTMF) to be transmitted. This is necessary for the sole purpose of supporting the call, not for the benefit of the user. In a SIP network, the offer/answer model can result in a party answering his or her phone prior to any media being made available. For example, a perfect session would mean that the INVITE would carry the offer (in the SDP) for the session. The response, then, would provide the answer (again in the SDP), and the session would be established. The facility is connected and the voice is sent after the 2xx response is received by the UAC. However, this is not always the case. Sometimes the offer is carried in the response itself, and the answer is provided in the ACK. This results in the voice being chopped because the UAC cannot provide resources for the session until the answer has been sent. This header was introduced to solve this problem. There are many instances where media need to be delivered prior to the session being completely established (as in the PSTN model). The receipt of DTMF tones for an interactive voice response (IVR), for example, warrants early media being made available and connecting, as does an announcement being delivered to the calling party prior to the call actually being connected. The purpose of this header is to notify originators of a request when early media need to be supported (this, again, is media transmission prior to the establishment of the session). Of course, care must be taken in SIP networks to prevent actual user data from being allowed during this time. The network proxies are responsible for ensuring that no user data is allowed to be sent during the early media period. This is analogous with PSTN networks where the trunk is cut through in the backward direction for the sole purpose of signaling tones and announcements, as well as digit collection, prior to the called party answering.

It has been suggested that some calls will require a higher QoS than others. This requires some fashion of enforcing QoS policy for authorized calls. This header was added as a means of communicating an authorization key to the UAC wishing to have QoS enforced for a specific request. The header is added by a proxy in the network that is configured to provide QoS support. The proxy must interface with an application providing the QoS authorization, so this does not necessarily mean that the proxy provides the authorization itself. The proxy simply provides an authorization token. The token must then be sent by the UAC to the entity providing the resource. This is outside the scope of SIP and is supported by other protocols (such as the Resource Reservation Protocol [RSVP]). A media gateway, for example, may interface to another function providing a media reservation. As part of the media reservation, QoS is enforced by the media resource reservation function, ensuring that a resource will be made available to the UAC. The UAC provides the token provided in this header to this reservation function to show that it is authorized to receive QoS. For example, a subscriber initiates a call by dialing digits. The UAC then inserts these digits into an INVITE and forwards the INVITE to the destination. The proxies within the network route the message to its destination, where the UAS examines the session description (SDP) to ensure it can provide the necessary resources for the session. The UAS then returns a final response to the UAC agreeing to support the session with the required resources. The message is then forwarded back through the same path as the initial INVITE. The proxy responsible for supporting QoS will then examine the SDP portion and send this information to a resource reservation function. The resource reservation function then verifies that the proper bandwidth is available to support the session, and provides an authorization token back to the proxy. This authorization token includes where the reservation is being held. The exchange of reservation information is exchanged using something other than SIP (such as RSVP). The UAC then receives the response containing the P-MEDIA-AUTHORIZATION header with the authorization token. This is then used by the UAC to send to the reservation function using RSVP, for example. The media path is then secured with the requested QoS supported. SIP is really providing a means in this case for communicating the proper credentials to be used by the reservation system, rather than providing the QoS function itself. This is important to understand, as SIP really is nothing more than a means to communicate call control information between the many different entities in the SIP network.
