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.
Interworking with third-party voicemail servers
MCP interworking with third-party voicemail servers does not involve additional software deployment to the third-party voicemail servers. The MCP SIP Application Module uses SIP to successfully communicate with third-party voicemail servers. For non-SIP-aware voicemail servers, a gateway between the MCP network and the legacy voicemail server is used, in which case the MCP SIP Application Module still relies on SIP to successfully communicate with that gateway (for example, the MCP SIP PRI Gateway connects the MCP network to a PRI trunk-based voicemail server).
The MCP SIP Application Module and the MCP SIP PRI Gateway can be upgraded independently of any third-party voicemail server (or necessary intermediary gateway). 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.
For information about the upgrade procedures of a specific third-party vendor’s voicemail server, please refer to the documentation provided by that third-party vendor.
