Custom call forwarding lets you forward calls only during specific days and times. Use this option when you want calls to follow a schedule instead of using Personal 24/7 Call Forwarding.
Using the Sync mobile app?
This article uses examples from the net2phone browser app in Google Chrome. To learn how to manage call forwarding from the mobile app, visit: Configure Call Forwarding in the Mobile App.
How to set up custom Call Forwarding in Sync
Follow the steps below to access your Call Forwarding settings, choose how calls should forward, and create one or more custom schedule intervals. Custom schedules can use recurring weekday rules, specific calendar dates, or a combination of both.
Step 1: Access your Call Forwarding settings
Follow the steps below:
- Open your Profile Settings.
- Click your profile icon in the top right corner.
- Click your name under Profile Settings.
- Click the Call Forwarding subtab on the left side.

Step 2: Choose your Call Forwarding options
Review the Call Forwarding options below before choosing the forwarding behaviour that matches your call handling needs.
Off
Off disables call forwarding entirely.

When Off is selected, you will see the message: Only your devices will ring, no calls will be forwarded.
Ring All
Ring All rings all configured destinations at the same time. Depending on how your account is set up, this can include:
- Your net2phone devices, such as the browser app, desk phone, or mobile app.
- Any Forwarding Numbers you have added.

The call is connected to whichever device answers first. If no one answers within the configured number of Phone Rings, the call is sent to voicemail or handled according to your company’s call flow. When Ring All is selected, you will see the message: Ring your Devices & Forwarding Numbers at the same time.
No Answer
No Answer only forwards calls when you do not answer on your net2phone devices.
- Your devices ring first for the number of rings set under Phone Rings.
- If you do not answer in time, the call is forwarded to your forwarding number or numbers.

This option is useful when you want calls to reach your desk phone or browser app first, and fall back to a mobile or external number only if you are unavailable. When No Answer is selected, you will see the message: If none of your devices answer, forward all calls.
Failover
Failover forwards calls only when your net2phone devices are unreachable. This may happen during an internet outage, power failure, or when your device is not registered.
- If your devices are online and available, calls ring your devices normally.
- If your devices are offline, calls are forwarded to your forwarding number or numbers instead.

This option is typically used as a backup or disaster-recovery setting. When Failover is selected, you will see the message: When your Devices go offline, forward all calls.
Forward Only
Forward Only sends all incoming calls directly to your forwarding number or numbers without ringing your net2phone devices.
- Calls bypass your browser app, desk phone, and other assigned net2phone devices.
- Use this option when you want calls to go directly to a mobile phone or another external destination.

When Forward Only is selected, you will see the message: Do not ring your Devices, forward all calls.
Phone Rings
The Phone Rings setting controls how long your devices ring before the call is forwarded or sent to voicemail. A common example is 4 Rings.
Ring duration can also affect which voicemail answers the call. If you are forwarding to a mobile phone and your mobile carrier’s voicemail picks up faster than net2phone voicemail, the mobile voicemail may capture the message first.
If calls are going to your mobile voicemail instead of net2phone voicemail, try reducing the number of rings under Phone Rings or adjusting your mobile carrier’s voicemail settings.
You can also adjust your rings before timeout in the Devices subtab of Profile Settings.

Pro tip: Ring timeout adjustment
When choosing how many rings to allow before timeout, consider the following:
- More rings gives you extra time to answer, but may increase caller wait time.
- Fewer rings reduces caller wait time, but gives you less time to answer and may result in more missed calls.
Call Screening
Call Screening helps you identify forwarded calls before you answer. When Call Screening is enabled, you will hear a brief system message indicating that the incoming call was forwarded through net2phone. Your device will then provide options to accept or deny the call.
Call Screening is helpful when forwarding calls to a mobile phone, where it may otherwise be unclear whether the call is personal or work-related.
Record the Caller’s Name
When Call Screening is enabled, you can also enable Record the Caller’s Name. With this setting active:
- The caller is prompted to state their name before the call connects.
- You will hear the recorded name when the call reaches your forwarding destination.
- You can then choose to accept or deny the call.
This option is useful if you receive calls from unknown numbers or want additional confirmation before answering forwarded calls on an external device.
Note: Record the Caller’s Name is only available when Call Screening is enabled.

Incoming Call ID for Forwarded Calls
When calls are forwarded to an external device, such as your mobile phone, your Caller ID may show your own number instead of the original caller’s number. Many mobile carriers block foreign Caller ID for forwarded calls to help prevent spoofing, so this setting helps prevent your carrier from rejecting forwarded calls.

Call Queue sign-in and Call Forwarding
If you are signed in to any Call Queue, call forwarding is automatically paused. While you remain signed in to a queue, all incoming calls follow the queue’s routing rules instead of your personal call forwarding settings.
Forwarded calls resume only after you sign out of the queue. This behaviour ensures that queue duties take priority and prevents calls from being diverted away from your group’s call flow.
When you are signed in to a call queue and have call forwarding enabled, the following warning message appears: Queue sign-in pauses call forwarding. Resume call forwarding by signing out of queues.

Step 3: Enable custom Call Forwarding
You can use a combination of weekday scheduling and specific calendar dates and times.
- Ensure the Call Forwarding toggle is enabled.
- Select a Call Forwarding Option from the dropdown menu.
- Add at least one Call Forwarding number, such as an external 11-digit number or an internal extension.
- At the top of the configuration menu, click the Custom toggle. The 24/7 option is disabled when Custom is selected.
- Under Choose between Weekdays or Calendar dates, you can:
- Set one or more Weekdays intervals.
- Set one or more Calendar intervals.
- Use a combination of both Weekdays and Calendar intervals.
- Set the time range for the interval, or click All Day to forward calls for the full day.
- Click Save before navigating away from the Profile Settings configuration menu.

Step 4(a): Create Weekdays intervals
Use a Weekdays interval when you want forwarding to repeat on the same days each week. For example, you can forward calls every Monday to Wednesday from 08:00 to 11:30.
- Click Add Weekdays Interval. A new row appears with:
- A date field for reference.
- Day buttons for S, M, T, W, T, F, and S.
- A time range field.
- An All Day shortcut and a trash can icon.
- Select the days of the week when forwarding should be active by clicking the day buttons. For example, click M, T, and W.
- Click the time range field and choose or type the start and end times when calls should be forwarded.
- To forward calls for the full day, click All Day. The time range updates to 00:00 - 23:59.
- Optional: Click Add Weekdays Interval again to create additional blocks for the same or different days. For example, you can create one block for mornings and another for afternoons.
- Optional: To remove a Weekdays interval, click the trash can icon at the end of that row.
- Click Save before navigating away from the Profile Settings configuration menu.

Step 4(b): Create a Calendar interval
Use a Calendar interval to forward calls only on specific dates or during a temporary date range. For example, you can create a Calendar interval for vacation coverage or a short-term schedule change.
- Click Add Calendar Interval.
- In the date field, click the Calendar icon.
The calendar picker opens with two months displayed at a time. Use the navigation arrows to change the displayed months. - Choose and select one of the following:
- Single Day to forward calls on one date.
- Date Range to select a start and end date. For example, Jan 28, 2026 - Jan 30, 2026.
- Set the time range for the interval, or click All Day to forward calls for the full day or date range.
- Optional: Click Add Calendar Interval again to create additional date-based rules.
- Optional: To delete a Calendar interval, click the trash can icon at the end of that row.
- Click Save before navigating away from the Profile Settings configuration menu.

Using Weekdays and Calendar intervals together
Custom schedules can include both Weekdays intervals and Calendar intervals. Call Forwarding turns on whenever the current date and time match any active interval in your schedule.
Use Weekdays intervals for recurring weekly schedules, and use Calendar intervals for temporary or date-specific coverage.
| Interval type | Best used for | Example |
|---|---|---|
| Weekdays | Repeating schedules that happen on the same days each week. | Forward calls every Monday to Wednesday from 08:00 to 11:30. |
| Calendar | One-time dates, vacations, temporary coverage, or short-term schedule changes. | Forward calls all day from Jan 28, 2026 to Jan 30, 2026. |
How overlapping intervals work
If two intervals overlap, Call Forwarding remains active; you do not need to remove an overlap unless it makes the schedule harder to review or maintain.
For example, you can forward calls every Monday to Wednesday from 08:00 to 11:30 using a Weekdays interval, and also forward calls all day from Jan 28 to Jan 30 using a Calendar interval. If both intervals apply at the same time, Call Forwarding remains active.
Tips and troubleshooting custom Call Forwarding
Use the table below to troubleshoot common custom Call Forwarding issues before changing your schedule or deleting intervals.
| Issue | What to check |
|---|---|
| No forwarding numbers are added | Calls will not forward until at least one forwarding number is saved. Add an external 11-digit number or an internal extension. |
| Mobile voicemail answers first | Reduce your Phone Rings setting, or adjust your mobile carrier’s voicemail timing if available. |
| Caller ID shows your own number | Some mobile carriers require this for forwarded calls. This is expected behaviour and helps prevent forwarded calls from being rejected. |
| International numbers fail | Your account or region may block international forwarding. Contact your administrator or net2phone Support if international forwarding is required. |
| Forwarding is not activating | Confirm that Call Forwarding is enabled, the forwarding option is not set to Off, and the current date and time match an active interval. |
| Times appear incorrect | Custom schedules follow the time zone set in your Profile. Update your profile time zone if the schedule is activating at the wrong time. |
| The schedule is difficult to manage | Remove unused or duplicate intervals with the trash can icon. Use fewer intervals when possible to make the schedule easier to review. |
| You need to pause forwarding temporarily | Set the forwarding option to Off, or remove the active schedule interval if you no longer need it. |
