Extensions, Voicemail Boxes, Phones & DIDs

Last updated · cacofonix 3.4.28 · getafix 3.2.65

In Sirius Telefonix, a 4-digit Extension is the universal routing address: every user phone line, call queue, IVR auto attendant, and inbound phone number (DID) resolves through an extension.

1. Extensions (/settings/extensions)

Open Settings → Extensions to view or edit extensions in your company (System Admins can click Add Extension to provision new ones):

  • Base Extension: Exactly 4 digits (for example, 1001 for an agent or 5100 for a queue; set at creation and read-only on edit).
  • User: The user account associated with this extension (leave blank for queue or IVR extensions).
  • Ring Duration: How many seconds (6 to 99, typically 40) a direct call to this extension rings before overflowing to personal voicemail (or returning busy if voicemail is disabled).

Configuring a Personal Voicemail Box

When your company has Voicemail Enabled, opening an extension displays a Voicemail button in the top-right corner of the editor:

  1. Click Voicemail to open the mailbox settings:
    • Basic Info: Set the Full Name, notification Email, and toggle Enabled / Disabled, then click Update (VoiceMail saved).
    • Security (visible when Enabled): Enter a numeric voicemail Password (PIN) of at least 5 characters and click Change Password (Password updated).
  2. How Users Access Personal Voicemail:
    • Web UI: In the Admin Console under Applications → Voice Mail Messages (/apps/voicemailmessages), where users can play, download, click-to-dial Call Back, or delete messages.
    • From a Phone: Dial *29 from the extension's registered phone and enter the voicemail PIN, or dial *<4-digit-extension> (e.g., *1001) during a call/IVR to drop a caller directly into that extension's voicemail greeting.

2. Phones & SIP Phone Lines (/settings/phones)

A Phone record groups one or more Phone Lines (SIP endpoints).

  1. Open Settings → Phones and click a Phone row to open it.
  2. Under Phone Lines, click an existing line to edit it (or Add Phone Line as a System Admin):
    • Extension: Select the 4-digit extension this line serves.
    • Caller Name: Display name shown on the Desk Call Card, Floor agent cards, and internal calls.
    • Description: Optional label (such as Browser Softphone or Yealink T46U).
    • SIP User Name: Automatically generated by the platform as <companyId>_<extension> (for example, acme_1001) and shown read-only when editing an existing line.
    • SIP Password: Must be 8 to 50 characters and include at least one letter and one digit. Click the eye icon to reveal the current password, or leave it blank when editing other fields to keep the existing password.
    • Call Waiting: Keep Call Waiting Disabled for agents using the Desk (fulliautomatix), as the Desk is designed around a single active call card. You may enable Call Waiting Enabled for standalone hardware desk phones that do not use the Desk.

Note: The Desk's built-in WebRTC browser softphone retrieves its user's SIP User Name and SIP Password automatically when the user signs in — you only need to copy these credentials manually when configuring a physical SIP phone or third-party softphone app.

3. Phone Numbers / Inbound DIDs (/settings/phonenumbers)

Inbound public telephone numbers (DIDs) are mapped to internal extensions under Settings → Phone Numbers:

  • Phone No: The public DID number delivered by the SIP carrier (read-only after creation).
  • Provider: The SIP trunk provider carrying this number.
  • Company: The tenant owning the number.
  • Extension: Select the 4-digit Extension that should answer inbound calls to this number:
    • Pointing a DID to an Auto Attendant's extension plays your IVR greeting to external callers.
    • Pointing a DID to a Queue's extension places external callers directly into that queue.
    • Pointing a DID to a User's extension rings that user's phone directly (DDI).
