Contact Methods

The Contact Methods section is where you manage all the ways calls can be handled in your phone system. This includes:

• App configurations for the phone system app
• SIP accounts for VoIP phones and softphones
• PSTN routing for forwarding to regular phone numbers
• External SIP URIs for routing to other VoIP systems
• Email addresses for receiving voicemails and call recordings

Common Settings

Inbound Calls Configuration

All contact methods (except email) share these common inbound call settings:

• DID Number: Select which FlyNumber rings to this contact method

  warning

  If you set a DID number here, you can't use it in a phone number module for call flows. Leave this empty if you want to use the number in a more complex call flow.

• Internal Number: Set an extension for internal calling

  • 1-4 digit number
  • Must be unique across your system
  • Used for quick internal dialing

• When unavailable: Choose what happens when calls can't be answered

  • Do Nothing: End the call
  • Route to Voicemail: Send to voicemail with selected greeting
  • Custom handling options may vary by contact method type

• Voicemail audio: Select greeting for voicemail (if enabled)

  • Choose from your uploaded audio files
  • Different greetings for different scenarios
  • Professional message recommendations

Integration with Call Flows

All contact methods (App configurations, SIP accounts, PSTN routes, and SIP forwarding) can be integrated into your call flows using the Ring Group module. This allows you to:

• Create complex routing scenarios
• Combine with other call handling features
• Set up conditional routing

tip

To use a contact method in a call flow:

1. Clear the DID number from the contact method's inbound settings
2. Use a Phone Number module connected to a Ring Group
3. Add the contact method as a destination in the Ring Group

You can enhance your call flow by adding other modules like:

• Time Router for schedule-based routing
• Voice Menu for interactive menus
• Other modules to build complex call flows

Call Transfers

Call transfer functionality allows callers to transfer calls to other numbers using feature codes. This applies to both SIP Accounts and PSTN Routes (regular phone number forwarding). When "Allow Call Transfer" is enabled in the contact method settings, callers can perform call transfers during a call.

To configure call transfers, you need to:

1. Enable Allow Call Transfer in the settings of your SIP Account or PSTN Route
2. Ensure the appropriate feature codes are set up in Settings → Feature Codes

There are two types of transfers available, here's how it could work:

1. Attended Transfer

• Press *11 during the call (using our example)
• Enter the destination number in E.164 format (without +) followed by #
• The system announces "Transfer"
• Speak with the new recipient first
• Complete the transfer after confirmation
• Return to the original caller if needed

Use Case

Perfect for when you need to:

• Confirm recipient availability
• Provide context before transfer
• Ensure a proper handoff

2. Unattended Transfer

• Press *22 during the call (using our example)
• Enter the destination number in E.164 format (without +) followed by #
• The system announces "Transfer"
• The call transfers immediately
• The original caller connects directly to the destination

Use Case

Ideal for:

• Quick transfers
• Known recipients
• Routine call routing

warning

Enabling call transfers may incur additional per-minute charges for the transferred calls.

App Configurations 📱

The App Configurations tab shows all users who have the phone system app configured. Here you can manage app settings like inbound/outbound calling options and recording preferences. Once configured, these app configurations can be used as destinations in your call flow with-in the ring group module.

Important

Unlike other contact methods which can be added directly in the Contact Methods menu, app configurations must be set up through the Users menu. See App Integration in Users for details.

There are two ways to set up app configurations:

1. For New Users:

   • Create a new user in the Users menu
   • Enable "Configure application line in the next step"
   • Complete the app configuration setup
   • User will receive an email with activation instructions

2. For Existing Users:

   • Ensure the user has an email address
   • Go to the Users menu
   • Use "Send invite to app" from the Actions menu
   • See Sending App Invitations for step-by-step instructions

The interface displays key information for each app user:

Field	Description
User	Name of the app user
Number	Assigned FlyNumber for inbound calls
Internal number	Extension for internal calling
When unavailable	Action taken when user can't answer
Enable external outbound calls	Whether external calling is allowed
Caller ID(s)	Numbers used for outbound calls
Caller ID name	Display name for outbound calls
Internal caller ID	Identity for internal calls

SIP Accounts 🌐

SIP accounts provide an alternative way to use your phone system with any SIP-compatible client. Instead of using the phone system app, you can configure your preferred SIP client (like Zoiper or Groundwire) using credentials provided by the system. Once configured, these SIP accounts can be used as destinations in your call flow with-in the ring group module.

Quick Start

For simple use cases, you can set up a SIP account here for inbound and outbound calls without needing to set up call flow logic. Just configure the account settings and start using it with your SIP client right away. For more complex scenarios, you can integrate the SIP account into your call flows using ring groups.

The SIP Accounts interface displays:

Field	Description
ID	Unique identifier for the SIP account
User	Name of the user assigned to this account
Number	FlyNumber assigned for inbound calls
Internal number	Extension for internal calling
When unavailable	Action taken when user can't answer
Allow Call Transfer	Indicates if call transfer is enabled

PSTN Routes (phone number forwarding) 📞

PSTN Routes allow you to forward calls from your FlyNumber to any regular phone number. Once you setup a route, you can then use the "contact method" anywhere in your call flow with-in the ring group module.

For simple forwarding needs, you can configure everything right here without creating complex call flows on the panel itself. Just select your FlyNumber and enter the destination phone number to get started.

note

There is a phone system specific per-minute rate when forwarding calls to regular phone numbers.

The PSTN Routes interface displays:

Field	Description
Destination Number	The phone number receiving forwarded calls
User	Name of the user this route is assigned to
Number	FlyNumber used for inbound calls
Internal number	Extension for internal calling
When unavailable	Action taken when destination is unreachable

  warning

  Enabling call transfers may incur additional per-minute charges for the transferred calls.

SIP Forwarding ↪️

The SIP Forwarding tab allows you to set your FlyNumber to ring directly to an external SIP address or URI. This can be an external VoIP provider or your own VoIP solution (Asterisk, FreeSwitch, 3CX, etc.). Once configured, these SIP forwarding rules can be used as destinations in your call flow with-in the ring group module.

General Settings

Configure the connection details for your SIP system:

• User: Select the user who will own this configuration
• Username: Your SIP username
• Domain: The SIP domain or IP address
• Port: The port number for SIP communication
• Network Protocol: Choose from:
  • IPv4 Only
  • IPv6 Only
  • Dualstack
  • IPv4 Preferred
  • IPv6 Preferred
• Process 30X redirects: Enable/disable SIP redirect handling

Compatible Systems

You can use SIP forwarding with various SIP-enabled systems and software including:

• Asterisk
• FreePBX
• FreeSwitch
• 3CX
• Any SIP-compatible PBX or provider

IP Whitelisting

If your SIP system or provider uses IP-based security, you'll need to whitelist our IP ranges:

46.19.208.0/21 (46.19.208.0 - 46.19.215.254) - for incoming and outgoing traffic

For RTP media, allow the following port range:

16384-32767

note

If your system accepts traffic from all IPs, whitelisting is not required (though not recommended for security reasons).

note

This is different from traditional call forwarding—instead of forwarding calls, you're configuring the number to connect directly to your SIP-enabled system or provider. Check out our blog post on Forwarding Calls vs Setting Calls.

Email Contact Methods 📩

The Email tab allows you to configure email addresses that will receive system notifications, voicemails, and call recordings. These email contact methods are used throughout the system whenever you need to send notifications or recordings to users.

The Email interface displays:

Field	Description
User	Name of the user this email is assigned to
Email	The email address for notifications
Status	Verification status of the email address

Creating an Email Contact Method

To add a new email contact method:

1. Click the + button in the bottom right corner
2. Configure the settings:

• User: Select the user who will own this email contact
• Email: Enter the email address that will receive notifications

Email Verification

After saving, a verification email will be sent to the provided address. The email contact method must be verified before it can receive notifications.

Domain Verification

For organizations adding multiple email addresses under the same domain, you can verify the entire domain instead of verifying each email individually. This is configured in Settings → Domains.

Domain Verification Benefits

• Validate an entire domain once
• Skip individual email verifications
• Streamline adding new users
• Perfect for larger organizations

To verify a domain:

1. Go to Settings → Domains
2. Enter your domain name
3. A TXT record will be generated
4. Add the TXT record to your domain's DNS settings
5. Click Verify to complete the process

note

DNS changes may take some time to propagate. If verification fails initially, wait a few minutes and try again.

Once a domain is verified:

• All email addresses from that domain are automatically verified when created
• No need for individual verification emails
• Faster setup for new users

info

Domain verification is optional. You can still verify email addresses individually if preferred.
