This can be configured in Cisco Unity Connection Administration> System Settings> Advanced> Unified Messaging Services> the TTS and Calendars: Time to Wait for a Response (in seconds) field.

This configuration is specified in either of the following ways: • In Cisco Unity Connection Administration> Users> Users> select a user> Edit> Send Message Settings> select the desirable action under the When a Call is Disconnected or the User Hangs Up field. • In Cisco Unity Connection Administration> Templates> User Templates> select a user template> Edit> Send Message Settings> select the desirable action under the When a Call is Disconnected or the User Hangs Up field. • If the mailbox quota is exceeded or the mailbox store size is exceeded, Unity Connection allows to record the message if the recipient mailbox has not exceeded the Send/ Receive Quota.

In addition to this, an administrator can also manage the message deletion to meet the disk capacity requirements and security needs.
