Webex Calling voicemail

Also known as Send calls to voicemail when unanswered, Voicemail Usage Stats, shared voicemail, voice portal, voicemail group.

Webex Calling routes unanswered calls to voicemail based on a ring count configured per user 9. Voice portals, user mailboxes, and shared voicemail groups provide message storage and retrieval options across the platform 17​13.

Mailbox configuration and limits

An unanswered call diverts to voicemail through the setting called send calls to voicemail when unanswered, which is set to a number of rings chosen from a list 9. Neither a default ring count nor a ring count range is published for this setting 9.

The user voicemail configuration publishes 5 settings that have explicit bounds but no published defaults 5:

• Message deletion: 1 to 180 days 5
• Passcode change window: 1 to 7 days 5
• Passcode expiry: 15 to 180 days 5
• Passcode history: 10 to 24 5
• Passcode length: 6 to 30 5

An internal mailbox holds a single message of at most 10 minutes, with a total limit of 100 minutes or 1,000 pages of fax 6. The total message count includes fax messages because fax and voicemail share this storage pool 6. Messages older than 180 days are archived automatically, and retrieving an archived voicemail requires a service request to Cisco 8. No held document states what happens when a mailbox reaches its storage limit 12.

Storage can be set to keep messages in the internal mailbox, send them to an email address, or both 7. Selecting an external mailbox routes every message to an email address, which eliminates access from the phone, the Webex App, and User Hub, and stops transcription 3. Sources disagree on transcription prerequisites, as the user voicemail article gives 3 different and mutually incomplete statements of what voicemail transcription requires before settling it in one place 15.

Access and voice portals

A voice portal provides the dialable number a user calls to access voicemail, and it enforces its own passcode rules 17. An organisation default voicemail passcode also grants access to other user services, including the single number reach portal and hoteling, while disabling hot desk sign-in through the voice portal 2.

A shared voicemail box is provisioned as a voicemail group in Control Hub to take messages for multiple users 13. A voicemail group has a single greeting covering both the no-answer and busy scenarios, and users access it through a shared passcode rather than a list of permitted users 14.

Reporting and records

The voicemail usage report contains 31 fields that describe the current state of a mailbox rather than historical events 16. Cisco states that this report is intended for operational monitoring and troubleshooting, not for billing purposes 16.

A call handled by voicemail is marked as answered in the detailed call history, where the user type field is set to voicemail retrieval 1. Outside this, the 3 voicemail feature articles do not mention call detail records, reporting, or call history 10. Neither voicemail article says what a voicemail leaves in a record, as report, call detail, and log each occur 0 times in both, and every occurrence of record is about recording a greeting 4. Furthermore, no held document states what occurs when a consult leg reaches voicemail, with the reports documentation never pairing the words "consult" and "voicemail" in the same sentence, and neither voicemail article mentioning "consult" at all 11.
