Digital Integration with Digital PIMG Units

The phone system sends call information, MWI requests, and voice connections through the digital lines, which connect the phone system to the PIMG units (media gateways). The PIMG units communicate with the Unity Connection server through the LAN or WAN using Session Initiation Protocol (SIP). Figure 1-1 shows the required connections for a digital integration using digital PIMG units.

DTMF Integration with Analog PIMG Units

The phone system sends call information, MWI requests, and voice connections through the analog lines, which connect the phone system to the PIMG units (media gateways). The PIMG units communicate with the Unity Connection server through the LAN or WAN using Session Initiation Protocol (SIP). Figure 1-2 shows the required connections for a DTMF integration using analog PIMG units.

Serial (SMDI, MCI, or MD-110) Integration with Analog PIMG Units

The phone system sends call information and MWI requests through the data link, which is an RS-232 serial cable that connects the phone system and the master PIMG unit (media gateway). Voice connections are sent through the analog lines between the phone system and the PIMG units. The PIMG units communicate with the Unity Connection server through the LAN or WAN using Session Initialization Protocol (SIP). Figure 1-3 shows the required connections for a serial integration using analog PIMG units.

Call Information

The phone system sends the following information with forwarded calls:

  • The extension of the called party

  • The extension of the calling party (for internal calls) or the phone number of the calling party (if it is an external call and the system uses caller ID)

  • The reason for the forward (the extension is busy, does not answer, or is set to forward all calls)

Unity Connection uses this information to answer the call appropriately. For example, a call forwarded to Unity Connection is answered with the personal greeting of the user. If the phone system routes the call without this information, Unity Connection answers with the opening greeting.


Note

Serial integrations send requests to turn on and turn off MWIs through the data link.

Integration Functionality

The PIMG integration provides the following integration features:

  • Call forward to personal greeting

  • Call forward to busy greeting

  • Caller ID

  • Easy message access (a user can retrieve messages without entering an ID because Unity Connection identifies the user based on the extension from which the call originated; a password may be required)

  • Identified user messaging (Unity Connection identifies the user who leaves a message during a forwarded internal call, based on the extension from which the call originated)

  • Message waiting indication (MWI)

Centralized Voice Messaging

Unity Connection supports centralized voice messaging through the phone system, which supports various inter-phone system networking protocols including proprietary protocols such as Avaya DCS, Nortel MCDN, or Siemens CorNet, and standards-based protocols such as QSIG or DPNSS. Note that centralized voice messaging is a function of the phone system and its inter-phone system networking, not voicemail. Unity Connection supports centralized voice messaging as long as the phone system and its inter-phone system networking are properly configured.
