Avaya Modular Messaging Concepts and 

Planning Guide

63. Different MAS units in a voice mail domain can have different 

peer Domino servers.

64. Different MAS units in a voice mail domain can have different 

directory servers that are replicants of each other.

65. Each directory server can be a server of more than one voice mail 

domain.

66. An e-mail server can be a peer server for more than one MAS.

67. An e-mail server can be a host to more than one voice mail 

domain.

68. A voice mail domain can have multiple e-mail servers.

69. A voice mail domain can contain a maximum of ten MAS units. 

If a dedicated is used to host the Tracing Server, or Offline Call 
Answer store, or both, this dedicated server does not count 
toward the maximum MAS units supported.

When implementing a Modular Messaging—Microsoft Exchange or 
Modular Messaging—IBM Lotus Domino configuration, planners must 
consider the proximity of the e-mail message store to the switch or 
communication servers. 

Messaging Application Server (MAS) units must be located on the same 
LAN as the message store. If the switch is at another location, 
arrangements must be made to get the traffic from the remote switch to 
the site with the e-mail server and MAS units. This can be accommodated 
by extending communication facilities or by networking traffic from the 
remote site(s) to a switch at the same location as the e-mail server and 
MAS units. 

Note: In a Modular Messaging—MSS system, the MAS units and 

the MSS are on the same private LAN, and are at the same 
location as the switch.
