Phone Numbers

To receive inbound phone calls, your AI agent needs an Indian phone number. Zentrix Agent Studio provides phone numbers through our verified Indian telephony partner, integrated natively with our voice AI platform.

How Numbers Work

Each phone number is a standard Indian landline or virtual number in the +91 format. When a customer calls the number, the call is routed through our telephony infrastructure to your AI agent, which handles the conversation in real time. See Inbound Calls for the detailed call flow.

Numbers are assigned to agent instances on a one-to-one basis by default -- one number per agent. In a multi-agent setup, a single number can route through multiple agents using the primary/secondary routing model.

Provisioning Types

Zentrix Agent Studio offers three ways to get a phone number:

Type	Markup	SLA	Setup Fee	Best For
Self-Serve	20% on base cost	4 business hours	Rs 0	Most customers -- fast and affordable
Managed	35% on base cost	24 hours	Rs 0	Customers who want us to handle everything
BYON (Bring Your Own Number)	0% markup	24-48 hours	Rs 1,499 one-time	Businesses with existing phone numbers

Self-Serve -- You request a number through the dashboard. The admin provisions it and assigns it to your agent. The base telephony cost is marked up by 20%.

Managed -- You tell us what you need, and we handle the entire setup. We select an appropriate number, configure it with your agent, and test the connection. The higher markup covers the hands-on service.

BYON (Bring Your Own Number) -- If you already have a business phone number, you can port it to our telephony platform and link it to your agent. There is no ongoing markup on telephony costs, but a one-time setup fee of Rs 1,499 covers the porting and configuration work.

Requesting a Number

1. Go to My Agents in your customer portal
2. Select the agent you want to assign a number to
3. Click Request Phone Number
4. Choose your provisioning type (Self-Serve, Managed, or BYON)
5. For BYON, provide your existing number and carrier details
6. An admin will process your request and assign the number

Once assigned, the number appears in your agent's dashboard alongside the call logs and other details.

Number Assignment

Numbers are linked to agents through our voice platform. When a number is assigned to an agent:

1. The voice platform links the agent to the phone number
2. The telephony infrastructure is configured to route inbound calls to the AI engine
3. Incoming calls are automatically routed to your AI agent

Multi-Agent Shared Numbers

In a multi-agent configuration, a single phone number can serve as the entry point for multiple agents. The primary agent (typically a Receptionist) answers all calls and routes to secondary agents based on the caller's needs. See Routing Config for details on how call routing works with shared numbers.

Number Inventory (Admin)

Administrators can view and manage all phone numbers from the Phone Numbers section in the admin panel. This includes:

• Viewing all numbers with their assigned agents
• Syncing number inventory from the voice platform using the Sync Numbers button
• Provisioning new numbers
• Viewing the telephony provider status

Telephony Costs

Phone number costs include two components:

• Monthly rental -- The telephony provider charges a monthly fee for the phone number itself
• Per-minute usage -- The telephony provider charges per minute of call time (inbound calls)

These costs are passed through to you with the markup percentage based on your provisioning type. Your Zentrix Agent Studio subscription (e.g., Rs 3,499/mo for AI Receptionist) is separate from telephony costs. See Pricing Tiers for full pricing details.
