Cellular service provider voice mail
Office stations can have standard Avaya server running Communication Manager voice mail coverage such as Communication Manager Messaging. But cell phones usually have voice mail coverage from the cellular service provider. There are now two ways to coordinate the two systems.
First, you can administer Communication Manager Extended Access Cellular Voice Mail Avoidance. Use the Cellular Voice Mail Avoidance feature to reduce the uncertainty as to where unanswered Extension to Cellular calls go. An unanswered call ends either at your office telephone voice mail, or at your cell phone voice mail system.
Communication Manager detects when the cell phone is not the entity that answers the call and brings the call back to the server. The call is treated as a normal call on the telephone with Extension to Cellular enabled. The call is then processed with the normal number of rings set on your call coverage.
Second, you can set up the number of unanswered rings so that one of the voice mail systems always answers first. However, there are coverage options in both the Avaya server running Communication Manager and the network that send a call immediately to the respective voice mail. Examples of these options include busy,
active,
or send-all-calls
in Communication Manager and cell phone unavailable
or network congested
in the network. Users must understand that an unanswered call can result in a voice mail message in either mailbox.
