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.

Note: Since the MCP and CS 2000 can be upgraded at different times, the two products are backwards compatible by one release.

Interworking with third-party gateways

MCP interworking with SIP-enabled third-party gateways does not involve additional software deployment to the third-party gateways. The MCP SIP Application Module uses SIP to successfully communicate with a third-party gateway that also speaks SIP. Each third-party gateway software release must be validated and certified against the current MCP release.

The MCP SIP Application Module and third-party gateways can be upgraded independently of one another. Refer to MCP SIP Application Module Basics for more information on upgrades to the MCP SIP Application Module.

For information about the upgrade procedures of a specific third-party vendor’s gateway, please refer to the documentation provided by that third-party vendor.

Interworking with Traditional Phones

MCP interworking with traditional telephones does not involve additional software deployment to the existing switching system. However, the SimRing feature on the TDM switch must be activated in order to route calls to CDS users.

The MCP network and SIP Multimedia PC Client (PC Client) may not be upgraded at the same time. As new CDS functionality is introduced in the network through MCP network node upgrades, the existing PC Clients must continue to interwork with the network. Therefore, the MCP network nodes must be backwards compatible with older PC Clients and MCP nodes. In addition, PC Clients (both Converged and non-Converged) must be backwards compatible with all previously released PC Clients, as different versions of the clients may co-exist in a given MCP network.
