SIP Trunking Quick Start

This guide will walk you through setting up your first SIP trunk and connecting it to a Convocore AI agent in just a few steps.

​
Prerequisites

Before you begin, make sure you have:
  • ✅ A Convocore account with an active workspace
  • ✅ A SIP trunk provider account (e.g., Twilio or Peoplefone)
  • ✅ At least one phone number from your SIP provider
  • ✅ A voice-enabled AI agent configured in Convocore
  • ✅ Access to the Convocore SIP server (provided by Convocore)

​
Step 1: Navigate to SIP Trunking

Log into your Convocore dashboard and navigate to the SIP section.
1

Open the Dashboard

Go to your Convocore workspace dashboard at https://convocore.ai/app/{region}
2

Find the SIP Menu

Look for the “SIP” option in the left sidebar navigation menu
3

Step 2: Add Your SIP Provider

Now you’ll configure your SIP trunk by adding your provider’s details.
1

Click 'New SIP Provider'

On the SIP management page, click the ”+ New SIP Provider” button in the top right

​
Step 4: Configure Your SIP Provider

Now you need to configure your SIP provider to route calls to Convocore’s SIP server.

​
Convocore SIP Server Details

Point your SIP provider to route calls to: 
IP Address: 161.35.79.143
Port: 5060
Protocol: UDP

​
Configuration Example (Twilio or Peoplefone)

If you’re using Twilio, here’s how to configure trunk forwarding:
1

Log into Twilio Console

Go to the Twilio Console at https://console.twilio.com
2

Create a SIP Trunk

Navigate to Elastic SIP Trunking → Trunks → Create new SIP Trunk
3

Configure Termination URI

Configure the termination URI as this will be used to route calls to the Convocore SIP server:Also configure the ACL configuration and credentials configuration:
4

Configure Origination URI

Add the Convocore SIP server as an origination URI:
sip:161.35.79.143:5060
5

Assign Phone Numbers

Associate your phone numbers with this trunk
The exact configuration steps vary by provider. Check your SIP provider’s documentation for specific instructions on routing calls to an external SIP endpoint.

​
Step 5: Test Your Connection

Time to make your first test call!
1

Verify Configuration

Double-check that your SIP provider, phone number, and agent are all configured correctly
2

Make a Test Call

Dial the phone number you configured from any phone
3

Listen for the Agent

Your Convocore AI agent should answer and begin the conversation
4

Check the Conversation Log

After the call, check your Convocore dashboard under Conversations to see the call transcript

​
Troubleshooting Connection Issues

If your test call doesn’t work, check these common issues:
  • Verify your SIP domain is correct
  • Check that your SIP provider is routing to the correct Asterisk server
  • Ensure your phone number is in E.164 format
  • Check your SIP provider’s codec settings (should support PCMU/PCMA)
  • Verify firewall rules allow SIP traffic (UDP 5060) and RTP traffic (UDP 10000-20000)
  • Ensure NAT traversal is configured if your Asterisk server is behind NAT
  • Double-check your SIP username and password
  • Verify the “Requires Authentication” toggle is set correctly
  • Check if your SIP provider requires IP whitelisting
  • Ensure your agent is voice-enabled
  • Check that the agent is assigned to the correct phone number
  • Verify the region setting matches your deployment

​
Step 6: Monitor and Manage

Your SIP trunk is now live! Here’s how to monitor and manage it:

​
View Active Phone Numbers

On the SIP management page, you can:
  • See all configured SIP providers
  • Expand each provider to view associated phone numbers
  • See which agent is assigned to each number
  • View call counts and statistics

​
Common Questions

The number of phone numbers you can configure depends on your Convocore plan. Check your workspace settings to see your current limits.
Yes! You can add multiple SIP providers to your workspace and manage them all from the same interface.
If your SIP provider experiences downtime, calls to your phone numbers will fail at the provider level before reaching Convocore. Consider setting up failover with your provider.
Yes, you can delete and re-add the phone number with a different agent, or use the edit function if available.
Concurrent call limits depend on both your SIP provider’s capacity and your Convocore plan. Check with both providers for specific limits.
Pro Tip: Set up multiple phone numbers with different agents to A/B test agent configurations and find what works best for your use case!
