Nortel Networks Confidential 3 Overview How is this chapter organized This chapter provides a high-level overview of the interworking between the Multimedia Communications Platform (MCP) and the following systems: • Primary Rate Interface (PRI)-enabled switches • SIP-T-based switches • third-party gateways • traditional phones • third-party voicemail servers Interworking with PRI-enabled switches The MCP uses the SIP PRI Gateway to perform interworking with PRI-enabled switches (switches with PR
Nortel Networks Confidential 4 Overview Supported services The SIP PRI Gateway supports the following call types: • SIP to PRI • PRI to SIP • PRI to PRI The SIP PRI Gateway supports the following call features: • Basic call: The ability to make a call. • Hold/Retrieve: The ability to hold and retrieve calls. • Call transfers: The ability to forward the call to a third party after the call is established. Call transfer is limited to SIP clients.
Nortel Networks Confidential • Overview 5 SIP/PRI mapping support, including: — Protocol parameter mapping — error codes — PRI cause values with SIP responses — presentation and screening indicators • PRACK: the provisional response acknowledge message that ensures that the ringing signal does not get lost. • Type of Server (ToS): The ToS bit can be configured to indicate the priority of the voice packet over data packet to ensure quality of service.
Nortel Networks Confidential 6 Overview Figure 1 shows a network view of the MCP/CS 2000 interconnection. The MCP configuration enables direct connection between the MCP and CS 2000 with no intervening SIP proxies. The CS 2000 and its associated media gateways are placed in the private managed network.
Nortel Networks Confidential Overview 7 The profile is added when a new domain is created in the MCP system. Note: The profile name in the TELEPROF table on the CS 2000 side must match the profile name in the PRODOMAIN table on the MCP side. Otherwise, interworking between the MCP and CS 2000 will not work. Call Forward Both the MCP and the CS 2000 support call forwarding.
Nortel Networks Confidential 8 Overview include the audio codecs supported by the gateways. For the SDP that is received from the CS 2000, the MCP fills in the missing mandatory parameters as specified in RFC 2327. Details on the restrictions on SDP are specified in the SN03 IP Gateway InterOP Requirements document. Recursive Search The MCP Back-to-Back User Agent (BBUA) handles SIP 302 responses to an INVITE sent out because of a received INVITE from the CS 2000.
Nortel Networks Confidential Overview 9 If the platform sending the INFO receives a response code other than the ones listed above, it treats the response as a valid audit response, and does not bring the call down. The CS 2000 sends a 200 OK for an empty INFO message and a 481 response code if the call leg does not exist. Supported media The following are the media supported by the interworking of MCP and the CS 2000: • G. 711 PCMU • G. 711 PCMA • G. 729 • G.
Nortel Networks Confidential 10 Overview line-based voicemail server requires that a Line Gateway be placed between the MCP network and the voicemail server. This Line Gateway would process SIP messages to/from the MCP network and create the corresponding line signalling to/from the line network. “Interworking with third-party voicemail servers” on page 13, provides more information about how the MCP interworks with non-SIP aware voicemail servers.
Nortel Networks Confidential Overview 11 Converged Desktop Services CDS enhances the end user’s communication experience in a variety of ways: • Advanced Call Handling: The user can use the MCP Personal Agent web pages to control the user’s availability. By providing this ability to CDS users, features not easily accessible on existing TDM switching systems now become viable.
Nortel Networks Confidential 12 Overview non-Converged) is the only endpoint that supports this functionality. The Web Client supports the reception of web pages, but cannot send web pages to a Converged PC Client. • Instant Messaging (IM): The Converged PC Client can send and receive messages from any client that supports the Nortel Networks IM format. All MCP clients support sending and receiving of instant messages with each other.
Nortel Networks Confidential Overview 13 other SIP endpoints (such as the SIP Multimedia Web Client or an i2004 controlled by the IP Client Manager (IPCM) for voice over IP calls. An MCP alias must be set up for each user so that the alias is the same as the Calling Line ID sent from the TDM switch to the MCP over PRI.

Nortel Networks Confidential 17 Upgrades How this chapter is organized This chapter provides information about upgrade procedures dealing with MCP interworking with the following other systems: • Primary Rate Interface (PRI)-enabled switches • SIP-T-based switches • third-party gateways • traditional phones • third-party voicemail servers Interworking with PRI-enabled switches MCP interworking with PRI-enabled switches does not involve additional software deployment to the PRI-enabled switches.
Nortel Networks Confidential 18 Upgrades independently of one another. Refer to MCP SIP PRI Gateway Basics and MCP SIP Application Module Basics for more information on upgrades to those nodes of the MCP network. Interworking with CS 2000 MCP interworking with the CS 2000 does not involve additional software deployment. The functionality exists in the SIP Application Module. Refer to the MCP SIP Application Module Basics for more information on upgrades.
Nortel Networks Confidential Upgrades 19 Compatibility is maintained by version identifiers included in an MCP user’s service package information. When new CDS functionality becomes available in the MCP network, older Converged PC Clients can continue to exist and operate in the upgraded MCP network; however, they won’t be able to access the new Converged PC Client services. Note: In general, MCP network is upgraded before the PC Client is upgraded.
