Setting Up Phone Numbers & SIP Trunks

Phone Numbers

VINSI.AI allows you to purchase and manage phone numbers directly from the dashboard. Open Phone Numbers in the AI Phone Agent product (it is also available under CRM → Admin → Phone Numbers). The page subtitle reads "Manage your phone numbers and agent assignments".

The table lists Phone Number, Trunk, Agent, Date Added, and Actions. Use the search box ("Search by phone number or agent...") to find a number. The Trunk badge shows your own trunk name, or VINSI.AI AGENT, VINSI.AI PHONE, or VINSI.AI FAX.

1. Click to purchase a new phone number
2. Enter a 3-digit Area Code
3. Click Search Available Numbers
4. Optionally narrow the results with "Filter by city or state…"
5. Click a number, then click Subscribe & Buy ($3/mo)
6. Complete the Stripe checkout. Once purchased, the phone number will appear in the phone numbers table

Assign AI Agent

A number doesn't have to be assigned to an AI agent—it can also be a member's line, a hunt group, a queue, or a fax number. See Phone Numbers for those uses. To have an AI agent answer a number:

1. Locate the phone number in the phone numbers table
2. Use the dropdown in the Agent column
3. Select the AI agent you want to assign (choose No Agent to clear it)
4. The selected agent will now manage calls for that number

Using Your Own SIP Trunk

If you prefer to use your own SIP infrastructure instead of purchasing a phone number, you can connect a SIP trunk.

1. Click from the Phone Numbers section
2. Fill in the Configure SIP Trunk fields:
   
   • Trunk Name (required) — a label to identify this SIP trunk in your account
   • Phone Number (required) — enter the number in E.164 format (e.g. +18001234567)
   • Inbound Call Setup — to receive inbound calls, set your Origination SIP URI at your provider to the URI shown in the modal, with weight = 1 and priority = 1
   • SIP Termination URI (required) — the SIP URI where outbound calls will be terminated (e.g. sip:example.com:5060)
   • SIP Username / SIP Password (optional) — credentials if your provider requires authentication
3. Click Configure Trunk to save and activate the SIP trunk

To change a trunk later, use Edit SIP Trunk and click Save Changes. Leave the password blank to keep the current one.
