Avaya Modular Messaging Concepts and 

Planning Guide

40. All MAS units must be on same LAN segment as the Microsoft 

Exchange server.

41. Each MAS has a single primary peer Exchange server. The 

administrator can configure the MAS to establish communication 
with another Exchange server to act as a peer when the current 
primary peer Exchange server goes offline. 

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

peer Exchange servers.

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

directory servers that are replicants of each other.

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

domain.

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

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

domain.

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

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

If a dedicated server 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.

49. Each MAS can have only one directory server. The directory 

server must be an Active Directory Domain controller configured 
as a global catalog.

50. An Exchange 2003 domain can contain more than one voice mail 

domain.

51. A voice mail domain can contain subscribers in different 

Exchange 2003 domains, provided subscribers are in the same 
forest.
