Communication Manager Extended Access Cellular Voice Mail Avoidance reduces the uncertainty as to where unanswered calls to the cell phone go for coverage. An unanswered call typically either ends at the corporate voice mail system or at the cellular service provider (CSP) voice mail system. You have limited control over the terminating voice mail system. You can administrator the number of ring cycles before a call goes to the corporate and cellular voice mail systems and enable Cellular Voice Mail Avoidance through Communication Manager.

The cellular voice mail system can lead to several problems for the user. The cellular network routes calls to cellular voice mail when any of the following conditions exist:

• Users do not answer a ringing call.

• The cell phone is in a bad coverage area.

• The cell phone is turned off.

With Cellular Voice Mail Avoidance, Communication Manager detects when the cell phone is not the entity answering the call and the call goes to Cellular Voice Mail. Communication Manager then brings the call back so that the call follows normal coverage treatment. The office telephone rings an appropriate number of times before sending the call to coverage.
