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. The MCP SIP PRI Gateway uses standard PRI protocols and is compatible with any PRI-enabled switch that understands these standard PRI protocols:

•AT&T 4ESS(AT4)

•AT&T 5ESS (E10)

•AT&T TR 41459

•Bellcore National 2

•ETSI

•ECMA-143

•ETS 300 102-1

•Northern Telecom DMS-100 (DMS)

•NIS A211-1

•QSig

Because SIP revisions are backwards compatible, the MCP SIP Application Module and the MCP SIP-PRI Gateway can be upgraded
