Carrier / Trunk Setup

In Vicidial, a carrierrepresents a SIP trunk or VoIP provider that connects your Vicidial server to the public telephone network (PSTN). Carriers handle the actual phone calls — routing your outbound calls to real phone numbers and delivering inbound calls to your server.

You need at least one carrier configured for Vicidial to make or receive calls. Multiple carriers can be configured for redundancy (failover), cost optimization, or geographic routing.

Example: IP Authentication Carrier

Example: Registration-Based Carrier

Dial Prefix Setting:

The dial prefix tells Vicidial how to route calls through this carrier. The phone number is appended automatically.

Vicidial supports multiple carriers with automatic failover. Configure in the campaign settings:

• Primary Carrier — Set as the default dial prefix in campaign settings.
• Failover Carrier — Use Vicidial's dial prefix routing or Asterisk dialplan to route to secondary carrier on failure.
• Round-Robin — Distribute calls across multiple carriers for load balancing.
• Cost-Based Routing — Use different carriers based on destination (domestic vs. international, per area code).

• Campaign CID — Default Caller ID set at the campaign level. All outbound calls show this number.
• List CID Override — Each list can have its own CID, overriding the campaign CID.
• CID Group — Rotate through multiple CIDs automatically (for local presence dialing).
• Per-Lead CID — Set CID per lead via custom field for maximum local presence.
• STIR/SHAKEN — Ensure your carrier supports STIR/SHAKEN attestation to prevent "Spam Likely" labels.
