How To Forward Calls On Landline: A Comprehensive Technical Configuration Guide
Call forwarding on a landline is achieved by inputting specific feature access codes (FAC) into your telephone keypad to redirect incoming signals from your Public Switched Telephone Network (PSTN) line to a designated external number. This process relies on activation codes typically starting with star (*) symbols, which trigger your service provider’s switching equipment to reroute voice traffic before it reaches your local terminal.
Pre-Procedure Requirements and Provider Verification
Before attempting to engage call forwarding, it is essential to verify that the service is provisioned on your current subscription plan. While most residential and small business landline packages include basic call forwarding, some digital voice services (VoIP) or legacy analog lines require a specific "Feature Pack" activation from the service provider.
- Essential Requirements:
- Active landline service with a dial tone.
- The 10-digit destination telephone number to which you intend to route calls.
- Knowledge of your local exchange carrier (LEC) specific star codes, as these may vary slightly by region or provider.
- Touch-tone telephone hardware capable of generating Dual-Tone Multi-Frequency (DTMF) signals.
Estimated duration for setup is under three minutes, with no additional hardware costs assuming the feature is included in your existing service bundle.
Execution of Call Forwarding Procedures
The following steps outline the standard North American Star Code protocol used by major telecommunications carriers. Note that if your line is provided through a cable company or a digital VoIP interface, these codes remain the standard industry protocol.
Step 1: Initiating the Forwarding Sequence
Pick up your landline handset and listen for a clear dial tone. Once confirmed, press the asterisk (*) key followed by the activation code. For standard call forwarding, the universal code is 72. You should hear a secondary dial tone or a series of confirmation beeps after entering this sequence.
Step 2: Inputting the Destination Number
Immediately following the confirmation tone, dial the full 10-digit telephone number where you wish to receive your calls. Do not pause for an extended period, as the switching equipment may time out if it does not detect the complete string of digits.
Step 3: Verifying Activation
After entering the 10-digit number, remain on the line for approximately three to five seconds. Most modern switching systems will provide a confirmation tone, which is typically a rapid series of beeps or a recorded voice announcement confirming that call forwarding has been successfully enabled. If you hear a busy signal or a reorder tone, the activation failed; replace the handset and repeat the process from Step 1.
Step 4: Deactivating Call Forwarding
To stop the redirection of calls, pick up the receiver and dial the deactivation code, which is typically *73. You will hear a confirmation tone indicating that the feature has been disabled and that your landline will once again process incoming calls locally.
Pro-Tip: Always perform a test call from a cellular device to your landline number immediately after activation to confirm the routing is successful and audio quality remains clear at the destination.
Warning: Be aware that long-distance charges may apply when forwarding calls from your landline to a number outside your local calling area. Verify your billing agreement to ensure you are not subject to per-minute roaming or toll costs.

Technical Parameters and Protocol Comparison
The following table outlines the standard Feature Access Codes (FAC) utilized in the majority of North American PSTN environments. While 72 and 73 are the industry standard for Call Forwarding Variable, specific carriers may deviate.
| Feature Type | Activation Code | Deactivation Code | Functional Description |
|---|---|---|---|
| Call Forwarding Variable | *72 | *73 | Redirects all incoming calls to a designated number |
| Call Forwarding Busy | *90 | *91 | Redirects calls only when the line is currently in use |
| Call Forwarding No Answer | *92 | *93 | Redirects calls if the line rings for a set duration |
| Remote Access Forwarding | Varies by ISP | Varies by ISP | Enables forwarding via an external phone line |
Common Failure Modes and Diagnostic Remedies
Identifying why a call forwarding sequence fails often involves checking the physical state of the line or the status of the provider-side settings.
- Failure: System produces a fast-busy signal immediately after entering *72.
- Root Cause: The feature is likely not enabled on your account profile, or you are attempting to forward to a restricted number (e.g., an international line without proper permissions).
- Actionable Fix: Contact your service provider’s customer support to confirm that "Call Forwarding Variable" is an active feature on your line.
- Failure: Call forwarding is active, but the destination phone never rings.
- Root Cause: The destination number entered was incorrect, or the destination provider is blocking the forwarded call due to caller ID spoofing triggers.
- Actionable Fix: Deactivate and re-activate the sequence, ensuring the full 10-digit number (including area code) is entered without pauses.
- Failure: The line rings at the landline instead of the destination number.
- Root Cause: The activation was not acknowledged by the central office switch, or the deactivation code was triggered inadvertently.
- Actionable Fix: Listen specifically for the confirmation tone after the final digit of your destination number; if this tone does not occur, the switch has not saved your routing preference.
Frequently Asked Questions
Does call forwarding impact the quality of the audio?
Yes, in some instances, call forwarding can introduce minor latency or a slight reduction in audio fidelity. This occurs because the call is essentially being bridged, meaning the carrier must process two legs of the call simultaneously, increasing the potential for signal degradation.
Can I forward my landline to an international number?
Most standard landline service plans restrict forwarding to domestic 10-digit numbers to prevent toll fraud. To forward to an international destination, you must usually contact your provider to authorize international dialing permissions, which may involve higher per-minute rates.
Will I still be charged for calls that are forwarded?
Yes, you are generally responsible for the cost of the call from your landline to the destination number. If the forwarded number is outside your local calling plan, the provider will apply long-distance or toll charges for the duration of the connected call.
How do I know if call forwarding is currently enabled?
If you suspect forwarding is active but are unsure, dial the deactivation code (*73) regardless. If the system was already disabled, you will typically hear a secondary dial tone or an error tone indicating no change was made, which serves as an unofficial status check.
Does call forwarding work if the power at my home is out?
Traditional copper-wire landlines powered by the central office will continue to function and maintain call forwarding status during a power outage. However, if your landline is provided via an optical network terminal (ONT) or a cable modem, the service will drop if your local power or the modem's battery backup fails.
