Moving from Unity Connection to Webex Calling voicemail

Verified 2026-09-25 · 54 sources · tier 2–6

Voicemail is built directly into the Webex Calling offer rather than delivered through a separate voicemail product 52. Webex Calling cannot integrate with a premises-based voicemail system such as Unity Connection or Unity Connection Express 31.

Architecture and platform differences

Cisco provides no native way to migrate existing Unity Connection voicemail messages or greetings into the Webex Calling native voicemail service 30. Cisco states that some of its third-party partners' migration tools can migrate some Unity Connection voicemail data, but Cisco does not name the tools or specify which data can be moved 32.

For architectures retaining Unity Connection, the Webex Calling Dedicated Instance add-on includes Cisco Unity Connection alongside Unified CM, Expressway, and optional IM and Presence, SME, and Emergency Responder (Americas only) 15. In Dedicated Instance, Unity Connection is installed during service activation and sized according to the Knowledge Worker count provided for each region 14. Customers may distribute users across Dedicated Instance and Webex Calling, but calling features are not harmonised between the two platforms 16.

In the field, during one university's transition to Webex Calling, users were informed that existing voicemails would not transfer and were advised to preserve any required messages prior to cutover 22. Field reports suggest that migrated users in that deployment had to manually set a new voicemail PIN in User Hub, re-record greetings, and re-enable voicemail-to-email directly in User Hub 23.

Location configuration and voice portals

To enable voicemail at a Webex Calling location, the administrator must configure the voicemail pilot number, also referred to by Cisco as the voice portal number 27. Cisco's migration design guidance instructs administrators to provision 1 DID for the voicemail number at each Webex Calling location 49.

Each Webex Calling location receives its own voice portal, which is assigned a phone number and extension from that location 54. The extension is typically the last 4 digits of the voice portal number 54. Each location's voice portal also has an administrator passcode configured in Control Hub that is available only to administrators 38.

Users access the Webex Calling voice portal by calling from their own number and entering their PIN, or from any phone by pressing * and entering their mailbox number and passcode 53. Cisco implementation guidance specifies acceptance tests to verify that mailboxes are correctly assigned, reachable internally and remotely, able to record, retrieve, and manage messages, and able to deliver notifications 4.

Mailbox settings and group features

Webex Calling supports shared voicemail and fax mailboxes designated as voicemail groups 39. Cisco migration design documentation lists specific use cases for voicemail groups:

  • Department or workgroup mailboxes 51
  • Voicemail destinations for auto attendants or hunt groups 51
  • Call queue overflow targets 51
  • Users requiring only a voicemail box 51

For user mailboxes, the internal storage option imposes a 10-minute limit on single messages and a total capacity of 100 minutes per mailbox 28. If fax messaging is enabled, voicemail and fax share an aggregate storage limit of 100 minutes of voice messages or 1,000 pages of fax 50.

Administrators can configure routing behaviors, notifications, and delivery modes for individual mailboxes:

  • Separate toggles govern sending calls to voicemail when the line is busy or when unanswered after a designated number of rings 5.
  • A destination number can be specified to route callers who press 0 while in the mailbox 47.
  • A per-user toggle controls receipt of new message notifications 29.
  • An "email a copy" setting delivers a copy of each voicemail recording to a specified email address while preserving the message in the internal mailbox 17.
  • An "external mailbox" option forwards all voice messages directly to a designated email address, preventing access from desk phones, the Webex App, or User Hub 18.

Greetings and auto attendant assets

Uploaded custom user voicemail greetings must be formatted as .wav files, 8 kHz, 8-bit mono, CCITT u-law, and must not exceed 2 MB 25. Uploading a new greeting file or recording a new greeting replaces the previous greeting 24.

Cisco's Unified CM to Webex Calling migration tool can ingest auto attendants using a Unity Call Handler .zip file created with the CallHandlerDataDump tool 1. The migration tool identifies an error condition where greetings cannot be found in Webex Calling, which it marks as not migratable 2. CallHandlerDataDump itself is not supported by TAC and lists supported Unity Connection versions 7.x to 11.x (version 1.0.11, last updated 2020-10-12) 6.

For data extraction, COBRAS (Cisco Unified Backup and Restore Application Suite) covers backup, restore, and migration for Unity Connection 7.x through 15, and is TAC supported on supported Connection releases 10. COBRAS message backups across all Connection releases store recordings inside ZIP files containing EML messages, allowing WAV attachments to be extracted using an email client 8. For Unity Connection 8 and later, the COBRAS Data Viewer can extract voice names and custom greetings as WAV files 7. Additionally, field reports suggest a community NodeJS tool uses CUPI to extract Unity Connection call handler greetings and uploads them via the Webex audio API at the organisation or location level 21.

Transcription

Voicemail transcription is enabled or disabled per location in Control Hub under Management > Locations 44. For transcription delivery, the user must have the internal mailbox configured, "email a copy" enabled, and reside in a location where transcription is activated 46.

Transcriptions are presented in the body of an email accompanied by the recording as a .WAV attachment, and can also be viewed within the Webex App 41. Voicemail transcription supports English, French, German, Italian, Japanese, and Spanish; however, Japanese is excluded in the Kingdom of Saudi Arabia region 43. Voicemails that are composed and sent, replied to, or forwarded directly from the Webex Calling voice portal are not transcribed 45.

PIN management and security rules

An organisation default voicemail passcode is configured in Control Hub under Services > Calling > Service Settings in the Voicemail Passcode section 12. Cisco describes this default passcode as assigned to new users added to the organisation 11. A user assigned the default passcode must reset it on their device or in the application prior to accessing voicemail 13. End users can also reset their voicemail PIN directly in User Hub under Settings > Calling > Voicemail > Reset voicemail PIN 48.

PIN configuration must comply with system rules:

  • Length must be between 6 and 30 digits 35.
  • PINs cannot contain repeated patterns, 4 or more identical digits consecutively, or 4 or more ascending or descending digits 37.
  • PINs must not contain the user's phone number or extension forwards or backwards, match the current PIN reversed, or match any of the preceding 10 PINs 34.
  • Administrators can optionally enforce an interval of 1 to 7 days between passcode changes and an expiry duration of 15 to 180 days 33.

Applicability

Applies to: Cisco Webex Calling, Cisco Webex Calling Dedicated Instance, Cisco Webex Calling migration tool, and Cisco Unity Connection. Deployments: on-premises, multi-tenant, and dedicated instance. Sources checked 2026-09-25. Voicemail transcription supports Japanese across supported regions, except in the Kingdom of Saudi Arabia region where Japanese is not supported 43. COBRAS supports Unity Connection 7.x through 15 10, while CallHandlerDataDump lists support for Unity Connection 7.x to 11.x 6. Extraction of custom greetings and voice names via COBRAS Data Viewer applies to Unity Connection 8 and later 7.
