Avaya Definity Gx/PBXLink Integration Guide for Cisco Unity 3.1
Programming the Avaya Definity/PBXLink Phone System
• The number of MWIs that will be activated when call traffic is at its peak.
• The number of AMIS delivery calls.
• The number of Media Master connections needed when call traffic is at its peak. (Media Master
connections are used by Cisco Unity web applications and e-mail clients to play back and record
over the phone.)
It is best to install only the number of voice messaging ports that are needed so that system resources are
not allocated to unused ports.
The Number of Voice Messaging Ports That Will Answer Calls
The calls that the voice messaging ports answer can be incoming calls from unidentified callers or from
subscribers. Typically, these voice messaging ports are the busiest. They also have the lowest port
numbers for the phone system. As a general guideline, assign a majority of the voice messaging ports to
answer calls.
You can set voice messaging ports to both answer calls and to dial out (for example, to set MWIs).
The Number of Voice Messaging Ports That Will Only Dial Out, and Not Answer Calls
Ports that will only dial out and will not answer calls can do one or more of the following:
• Notify subscribers by phone, pager, or e-mail of messages that have arrived.
• Turn MWIs on and off for subscriber extensions.
• Make outbound AMIS calls to deliver voice messages from Cisco Unity subscribers to users on
another voice messaging system. (This action is available only with the AMIS licensed feature.)
• Make a Media Master connection so that subscribers can use the phone as a recording and playback
device in Cisco Unity web applications and e-mail clients.
Typically, these voice messaging ports are the least busy ports. They also have the highest port numbers
for the phone system. As a general guideline, assign a minority of the voice messaging ports to dial out.
Caution In programming the phone system, do not send calls to voice messaging ports in Cisco Unity that cannot
answer calls (voice messaging ports that are not set to Answer Calls). For example, if a voice messaging
port is set only to Dialout MWI, do not send calls to it.
Preparing for Programming the Phone System
Record your decisions about the voice messaging ports to guide you in programming the phone system.
Programming the Avaya Definity/PBXLink Phone System
If you use programming options other than those supplied in the following procedure, the performance
of the integration may be affected.
If you want to remap extension numbers (for example, when multiple subscribers use a single phone, or
when multiple extension numbers on a single phone should go to a single subscriber greeting), see
“Appendix: Remapping Extension Numbers” section on page 31.
