Nortel Networks Confidential 3 Overview How this chapter is organized The SIP Application Module Overview contains the following subsections: • “Overview” on page 4 — Functional description — Network configuration — Interfaces — Protocols • “Hardware” on page 11 • “Services and features” on page 11 — “Routing and Translation services” on page 12 — “Interworking services” on page 16 — “Service package enforcement” on page 17 — “Authentication services” on page 17 — “Network/Address Hiding service” on
Nortel Networks Confidential 4 Overview Overview The SIP Application Module is a service execution engine that provides the following functionality: • core signaling functionality enabling communication among SIP clients • SIP proxy server • Back-to-Back User Agent • SIP Registration • CPL interpretation • Location server • optional Presence subscription and notification (For more information on the Presence feature, see the MCP SIP Presence Basics document.
Nortel Networks Confidential Overview 5 — changing IP addresses in the contact header so that the SIP Application Module remains on the signaling path — modifying the Session Description Protocol (SDP) using values supplied by the RTP Media Portal to control media endpoints — providing advanced screening capabilities The architecture of a BBUA service consists of two user agent clients linked back-to-back through a proprietary interface.
Nortel Networks Confidential 6 Overview • Redirect Server The SIP Application Module decides whether to proxy or redirect the call separately for each individual request. This decision is made based on subscriber service logic. If the decision is to redirect the request, a 302 Response message is returned with a list of alternate locations. • Registration Server The Registration Server performs registration on messages it receives from clients.

Nortel Networks Confidential 8 Overview Interfaces The SIP Application Module interfaces with numerous other components. See Figure 3, “Network interfaces.” Figure 3 Network interfaces Private network PSTN or PBX Public network Access client NN10029-111 Standard MCP 1.1 FP1 (02.
Nortel Networks Confidential Overview 9 Protocols The SIP Application Module uses various protocols to support SIP clients, including the Management Module, RTP Media Portal, Database Module, and the PSTN Gateways. The protocols use an IP backbone to connect the components. These interfaces are shown in Figure 3, “Network interfaces.
Nortel Networks Confidential 10 Overview Table 1, “SIP Application Module protocols,” gives details about these interfaces.
Nortel Networks Confidential Overview 11 Hardware Refer to Table 2, “Minimum hardware requirements,” for the list of required hardware.
Nortel Networks Confidential 12 Overview • Service package enforcement • Authentication services • Converged PC service • Network/Address Hiding • 911 Notification support • Instant Messaging • Presence • Voicemail server interoperability and MWI (message waiting indication) notification • Registration • Network address book • Overload control • Reliability and fault tolerance Routing and Translation services Foreign termination If an incoming request specifies a domain that is not
Nortel Networks Confidential Overview 13 details). If this step also fails, the SIP Application Module attempts a general DNS A-record lookup to route the request. Note: The DNS A-record is the traditional response given by a DNS. It translates a domain name into an IP address. If any of these steps succeed, the SIP Application Module routes the request. If all these methods fail, the SIP Application Module rejects the request.
Nortel Networks Confidential 14 Overview These routes include routes for private digit dial plans, routes to gateways, and telephony-style routing between SIP domains. Multiple lists can reuse the same routes in a route list. • assign class of service (COS) COS is basically used to block particular types of calls, such as international dialing or long-distance dialing. For example, telephones in an office lobby can be restricted to local and emergency calls only in a domain.
Nortel Networks Confidential Overview 15 URL addresses specifying an appropriate gateway. It supports the use of digit translation and digit manipulation. A route list is assigned a single COS. The route list provides the following additional options that can restrict incoming sessions from using the domain’s telephony resources: • allow/block all incoming sessions from other domains • allow/block all incoming sessions from other subdomains • redirect session to the originator’s domain.
Nortel Networks Confidential 16 Overview With simultaneous ringing, the call terminates to multiple routes at the same time. The first terminating route to answer is accepted and the rest of the routes are released. With sequential ringing, the call tries to terminate to only one of several routes at a time. Route advancement occurs whenever an error response is received, a provisionable No Answer timer expires, or a redirect response is received.
Nortel Networks Confidential Overview 17 devices. Information for each component is stored in .xml format to provide flexibility when describing the capabilities of the component. Bearer Path Control The SIP Application Module uses the RTP Media Portal to control media streams originating from and terminating to non-compliant SIP devices if they do not support media negotiations. The exception to this occurs when the originating and terminating parties are both the same device type.
Nortel Networks Confidential 18 Overview authentication fails since the database does not have the subscriber's information. As a result, the call is blocked. Administrators can configure whether they want a call from an unknown foreign domain authenticated or not. System administrators can also specify foreign proxies in the NodalAuth field of the Authentication tab. In this way, no requests originating from those proxies are failed because of authentication.
Nortel Networks Confidential Overview 19 The Converged service adds the following capabilities to the end user's telephony service: • the ability to manually redirect incoming calls to another party from the PC • the ability to set up automated enhanced routing and screening of incoming calls based on time of day or based on the calling party's identity • a call log of all incoming calls • the ability to send instant messages to the party on the other end of a call • the ability to start collabor
Nortel Networks Confidential 20 Overview The RTP Media Portal handles Network Hiding for the media stream. For information on the RTP Media Portal, refer to the MCP RTP Media Portal Basics document. Note: The SIP Application Module cannot map SDP information without an RTP Media Portal. It only performs address mapping for SIP header fields. Therefore, SDP passes through untouched. If the server must map SDP address information, then you need an RTP Media Portal.
Nortel Networks Confidential Overview 21 Figure 6 RTP Media Portal interworking with Enterprise or foreign clients Enterprise Domain Public Domain SIP Client SIP Client SIP SIP MGCP+ RTP/RTCP RTP/RTCP RTP/RTCP Media Portal 911 Notification support The SIP Application Module supports Instant Message notifications to a specified On-Site Notification (OSN) location whenever a user makes a call to an emergency number such as 911.
Nortel Networks Confidential 22 Overview For more information and the procedure for setting up Instant Message notifications to emergency numbers, see the SIP Provisioning Client User Guide. Instant Messaging Instant Messages are routed in parallel only to a subscriber's dynamically registered routes (see “Registration—static and dynamic” on page 24). This is in contrast to session initiation requests, which are subject to CPL routing logic.
Nortel Networks Confidential Overview 23 transmits the following information over a data link to a voicemail server: • the called number (terminating party's telephone number) • the calling number • the type of call forwarding (for example, due to a busy line, an unanswered call) This feature also provides an interface to pure IP solutions that use a SIP-enabled voicemail server.
Nortel Networks Confidential 24 Overview and has messages waiting, the system sends a Notify to the client. • MESSAGE RETRIEVAL: A subscriber calls the voicemail server for message retrieval. The subscriber is then connected to the voicemail server and accesses the mailbox to retrieve messages. When you provision the voicemail server, specify which SIP Application Module is the host (see the Configuration chapter in this document for details).
Nortel Networks Confidential Overview 25 Network address book Client Address Book information is stored in the network so that it can be accessed from all clients. The information is downloaded in bulk whenever a client comes on line (either through a Simple Object Access Protocol [SOAP] interface or direct database access depending on the client). In order to receive updates to the Address Book after the initial download, the client subscribes to the Address Book event package and updates it as needed.
Nortel Networks Confidential 26 Overview Reliability and fault tolerance The SIP Application Module provides reliability and fault tolerance through multiple SIP Application Modules deployed in an N+M active-standby configuration.
Nortel Networks Confidential Overview 27 these sessions either receive no indication or continue to hear an alerting tone for an indefinite period of time. Manual failover There are two recommended procedures for manually initiating the fail-over of an active instance to a Standby node: the initiation of discrete LOCK and UNLOCK actions, or the initiation of a restart.
Nortel Networks Confidential 28 Overview Restart If you want to simply force an immediate manual fail-over, then you can request a Restart from the Management Console. WARNING The N+M reliability strategy provides a highly available service environment. The fail-over mechanisms enable an instance of the SIP Application Module to survive failure condition(s) by migrating to a standby server where it can resume the processing of new sessions.
Nortel Networks Confidential 29 Upgrades For information on upgrading from one full release to another, refer to the Installation and Commissioning document you receive with the upgrade.

Nortel Networks Confidential 102 Appendix A: Basic call flows 4. Client A sends an ACK message to the SIP Application module, which sends the ACK on to Client B. Note: The terminating client starts sending packets. The connection is established. 5. Client B sends Bye to end the call. 6. Client A responds with a 200 OK. Call transfer Figure 3, “Call transfer to client diagram,”and Figure 4, “Call transfer (blind) to client call flow,” show the basic call flow for a call transfer.

Appendix A: Basic call flows Nortel Networks Confidential The following steps provide more detail about the call flow: 1. Client A initiates the transfer of B to C. A selects blind transfer. 2. The SIP Application Module sends a Hold to B. 3. Client B sends a 200 OK message back to the SIP Application Module. The 200 OK messages contain an Allow Header, which lists the SIP methods that the client being transferred supports.

Nortel Networks Confidential Appendix A: Basic call flows 107 22. SIP Application Module sends an Invite (Unhold) to Client B. 23. Client B responds with a 200 OK. 24. The SIP Application Module sends the Invite to Client A. 25. Client A responds with an Ack. 26. The SIP Application Module sends an Ack to Client B and the call is re-established. Authentication Figure 6, “Authentication diagram,”and Figure 7, “Authentication call flow,” show the basic call flow for Authentication.
Nortel Networks Confidential 108 Appendix A: Basic call flows Figure 7 Authentication call flow SIP Application Module Client A Database 1. Register 2. 100 Trying 3. Retrieve user profile 4. 401 Unauthorized 4. 401 Unauthorized 5. Register 6. 100 Trying 7. Add user 8. User registered 9. 200 Registration successful The following steps provide more detail about the call flow: 1. Client A sends a Register (SIP) message to the SIP Application Module.
Nortel Networks Confidential Appendix A: Basic call flows 109 5. Client A sends another Register (SIP) message to the SIP Application Module. 6. Again, the SIP Application Module returns a 100 Trying message to Client A. 7. The SIP Application Module tells the Database Module to add this user to the registration tables (SQL). 8. The Database Module tells the SIP Application Module that the user is registered (SQL). Nothing is returned unless there is an error.
