Use this article to prepare your Sync phone service before you are away from work. You can forward calls to an external number for a specific date range, update your voicemail greeting, and enable voicemail-to-email so missed calls are easier to manage.

Requirements and notes

  • Some settings may depend on your assigned licenses and company permissions.
  • Administrators can update some call routing and voicemail settings for Team Members in the Sync Settings portal.
  • Forwarding calls to external numbers, including mobile numbers, may be affected by carrier behaviour, call screening settings, and company call routing policies.
 

Choose your out-of-office routing method

Before you update your settings, decide how incoming calls should be handled while you are away.

Goal Recommended Sync setting
Send calls to your mobile phone or another external number Enable Call Forwarding, add a forwarding number, and create a Calendar interval.
Forward calls only during specific dates Create a custom Calendar interval for your out-of-office date range.

Open your Profile Settings

Open your Profile Settings to update your personal Call Forwarding and Voicemail settings.

  1. Open the Sync app.
  2. Click your profile icon in the top right corner.
  3. Click your name under Profile Settings.
Profile Settings menu in the net2phone browser app
Example: Profile Settings menu in the Sync browser app.

Forward calls during a date range

Use a custom Calendar interval when you want calls to forward to an external number only while you are out of office. Calendar intervals are useful for vacations, temporary coverage, or planned time away from work.

  1. From Profile Settings, click the Call Forwarding subtab on the left side.
  2. Ensure the Call Forwarding toggle is enabled.
  3. Add the external number that should receive your calls while you are away. 
    External numbers should be entered as full 11-digit phone numbers. For example: 16135551234.
  4. Open the Call Forwarding Option dropdown menu.
  5. Select Forward Only.
  6. At the top of the configuration menu, click the Custom toggle.
Call Forwarding settings with Custom scheduling enabled
Example: Call Forwarding is set to Custom, scheduling is visible, and the call forwarding option is set to Forward Only.

Create a Calendar date range

Create a Calendar interval to choose the exact dates when out-of-office forwarding should be active.

  1. Click Add Calendar Interval.
  2. Click the Calendar icon in the date field.
  3. Select the start date and end date for your out-of-office period.
  4. Set the time range for the interval, or click All Day to forward calls for the full date range.
  5. Click Save before leaving the Profile Settings menu.
Calendar interval configured for all day forwarding from Jan 28 to Jan 30, 2026
Example: Calls are forwarded all day from Jan 28, 2026, to Jan 30, 2026 from 00:00 to 23:59.

Example: Out-of-office date range

To forward calls while you are away from Jan 28, 2026 to Jan 30, 2026, create a Calendar interval for that date range, select All Day, and choose Forward Only as your Call Forwarding option.

 

Mobile voicemail may answer first

Mobile carrier voicemail may answer before net2phone voicemail if the forwarded call rings for too long. Keep your ring duration reasonable if you want missed calls to return to your net2phone voicemail inbox.

 

Update your voicemail greeting

Update your voicemail greeting so callers know you are away and understand when they can expect a response.

  1. From Profile Settings, click the Voicemail subtab on the left side.
  2. In the Greeting section, preview your current greeting.
  3. Choose one of the available greeting options:
    • Default Voicemail Greeting
    • Custom Voicemail Greeting
    • Record Greeting via Phone
  4. Record or upload your out-of-office greeting.
  5. Click Save.
Voicemail subtab within Profile Settings
Example: Voicemail settings, including greeting and voicemail-to-email options.

Voicemail greeting for OOO

Include the date you return, whether callers should expect a delayed response, and who they can contact for urgent assistance.

 

Enable voicemail-to-email

Voicemail-to-email sends voicemail notifications to your email inbox, which can make missed calls easier to review while you are away.

Admins: Allow voicemail-to-email for your organization

Administrators must configure voicemail-to-email settings for Team Members in the Sync Settings portal before this feature can be used. For more information, refer to: Manage Voicemail-to-Email Settings.

 
  1. From Profile Settings, click the Voicemail subtab on the left side.
  2. Ensure your voicemail inbox is enabled.
  3. Enable the toggle labelled Email me when I get a new voicemail.
  4. Select which details to include in the email notification:
    • Include Audio File Attachment – attaches the voicemail audio file to the email.
    • Include Audio Transcript – includes a text version of the voicemail message, if available.
    • Include Caller Details – includes caller information, such as phone number and call details when available.
  5. Click Save.
Voicemail-to-email enabled with all optional inclusions selected
Example: Voicemail-to-email enabled with all optional inclusions selected.

Admin options for Team Members

Sync Administrators can update some Team Member call routing and voicemail settings from the Sync Settings portal. Admin updates are useful when a Team Member is away unexpectedly or needs help preparing their out-of-office routing.

Administrators may be able to update a Team Member’s forwarding behaviour, voicemail settings, or related call handling options, depending on the Team Member’s licenses and company permissions.

Administrator note

User-facing Profile settings and administrator-facing Team Member settings are separate workflows. Use the Sync Settings portal when you need to update settings on behalf of another Team Member.

 

Tips and troubleshooting

Use the table below to review common out-of-office setup issues before changing your forwarding schedule or voicemail settings.

Issue What to check
Calls are not forwarding Confirm Call Forwarding is enabled, the forwarding option is not set to Off, and the current date and time match your Calendar interval.
No forwarding number is saved Add and save at least one external 11-digit number before enabling the out-of-office schedule.
Calls go to your mobile voicemail Reduce your Phone Rings setting, or review your mobile carrier voicemail timing if available.
Caller ID shows your own number Some mobile carriers require this for forwarded calls. This expected behaviour helps prevent forwarded calls from being rejected.
The schedule activates at the wrong time Confirm the time zone set in your Profile Settings.
Voicemail-to-email is not available Confirm your voicemail service is enabled and ask an Administrator to confirm that voicemail-to-email is allowed for your organization.
A Team Member cannot update their own settings Ask a Sync Administrator to review the Team Member’s licenses, permissions, and profile settings in the Sync Settings portal.
