Requirements for SIP Trunk Integrations

💰 Paid Plan Feature: SIP Trunk integration is available on paid plans only. Free tier users can integrate Twilio SIP Trunks as an alternative.

Overview

SIP (Session Initiation Protocol) Trunks allow you to connect your existing telephony infrastructure with Vodex.ai for seamless call routing and management. This guide outlines the technical requirements and information needed for successful SIP Trunk integration.

Required Information

To integrate a SIP Trunk with Vodex.ai, you’ll need to provide the following technical details:

1. Connection Details

🌐 IP Address or FQDN

IP Address: Static IP address of your SIP Trunk providerFQDN: Fully Qualified Domain Name (e.g., sip.yourprovider.com)Example: 203.0.113.10 or trunk.siprovider.com

🔌 Port Configuration

SIP Port: Usually 5060 (UDP) or 5061 (TLS)RTP Port Range: For media transmissionExample: 5060 or 5061

2. Authentication (If Required)

Authentication is only required if your SIP Trunk is not configured for peer-to-peer connection.

Field	Description	Example
Username	SIP authentication username	`vodex_user_123`
Password	SIP authentication password	`SecurePass123!`
Realm	Authentication realm (optional)	`sip.provider.com`

3. Caller Line Identification (CLI)

CLI management allows Vodex to handle caller ID presentation and routing.

CLI Requirements:

Format: E.164 format preferred (+1234567890)
Validation: Must be authorized by your SIP provider
Presentation: Configure how caller ID appears to recipients

4. DID Configuration (Optional)

DID Range

Specify the range of Direct Inward Dialing numbers available:

Start DID: +1234567000
End DID:   +1234567999
Total DIDs: 1000 numbers

DID Prefix

Configure number formatting and routing:

Country Code: +1
Area Code: 234
Prefix: 567
Format: +1234567XXXX

SIP Trunk Types

Peer-to-Peer Connection

Authentication: Not required
Security: IP-based authentication
Configuration: Simpler setup
Use Case: Direct carrier connections

Registered Connection

Authentication: Username/Password required
Security: Credential-based authentication
Configuration: More secure
Use Case: Third-party SIP providers

Technical Requirements

Network Configuration

Firewall Configuration

Open required ports for SIP signaling and RTP media:

SIP Signaling: 5060 (UDP) or 5061 (TLS)
RTP Media: 10000-20000 (UDP range)

NAT Considerations

Configure NAT traversal if your SIP Trunk is behind NAT:

Enable STUN/TURN servers if needed
Configure proper port forwarding

Quality of Service

Implement QoS policies for optimal call quality:

Prioritize SIP and RTP traffic
Ensure sufficient bandwidth allocation

Codec Support

Vodex.ai supports the following audio codecs:

Codec	Bitrate	Quality	Bandwidth Usage
G.711 (PCMU/PCMA)	64 kbps	High	~87 kbps
G.729	8 kbps	Good	~31 kbps
G.722	64 kbps	HD Audio	~87 kbps

Free Tier Alternative: Twilio Integration

Free tier users can integrate Twilio SIP Trunks for telephony functionality.

For free tier users, consider using Twilio SIP Trunks:

Create Twilio Account: Sign up at twilio.com
Configure SIP Trunk: Set up SIP trunk in Twilio console
Get Credentials: Obtain SIP domain and authentication details
Integrate with Vodex: Use Twilio SIP credentials in Vodex configuration

Twilio SIP Configuration Example:

SIP Domain: yourapp.sip.twilio.com
Username: Your Twilio Account SID
Password: Your Twilio Auth Token
