Types of Phone Numbers
Learn about the different types of phone numbers you can use with VoxLink.ai: dedicated numbers, SIP integration, and Caller ID
VoxLink.ai lets you connect three different kinds of phone numbers to your AI assistant:
Normal (Dedicated) Numbers
- Rented directly from VoxLink.ai.
- Can be used for both inbound and outbound calls.
- Typically charged as a monthly rental, with the ability to handle multiple parallel calls on a single number.
SIP Integration (VOIP/PBX)
- Connect an existing VOIP or PBX number via SIP.
- This setup allows you to keep your existing numbers while benefiting from VoxLink.ai's AI.
- Works for both inbound and outbound—see our SIP Integration Guide for setup instructions.
- You can configure this directly in your dashboard under Phone Numbers.
Caller ID (Outbound Only)
- When you already have a phone number (e.g., your personal or business line) but don't want to port it or integrate via SIP.
- You verify ownership (via OTP or a short call) so that number can appear on people's caller ID.
- Inbound calls won't be answered by the AI if you use Caller ID alone—it only masks the AI's outbound calls.
Choosing the Right Option
- If you need inbound and you don't already have a VOIP solution, consider renting a dedicated number.
- If you have an established PBX or VOIP provider, use SIP integration.
- If you just want to do outbound calls showing your existing phone line, pick Caller ID.
