​
Step 1: Create Elastic SIP Trunking

  1. Create the trunk, give it a name, and toggle some general settings

  2. Setup termination (this is for outbound)

  • the termination SIP URI here is important, we would use it in later steps. You might want to use a localized termination uri that’s near your region. You can expand and view your localized uris in the twilio console.

  • For your elastic SIP trunk to accept our outbound request, you need to whitelist IP address or create a auth with username and password.

  • Currently Autocalls SIP server does not have a static IP, so if you opt for the IP route, you need to whitelist all the IP addresses in the range like following:

  1. Setup origination (this is for inbound)

  • Here you will specify Autocalls SIP server address as the origination SIP URI: sip:5wed79aeavr.sip.livekit.cloud

​
Step 2: Move numbers to Elastic SIP Trunking

You’ve created the elastic SIP trunk, now you would need to purchase numbers / move existing numbers to this trunk.

​
Step 3: Import numbers to Autocalls

Now the number is set up with your elastic SIP trunking, you need to import the number to Autocalls so that we will know how to route the call.

  1. Go to your Autocalls.ai dashboard

  2. Navigate to ** Your Phone Numbers**

  3. Click “Integrate SIP trunk”

  4. Fill in your details based on your integration type

Phone number: e.g., +1 555 0123
Username: Your extension username
Password: Your extension password
  1. Here you will supply the termination SIP URI you set up in Step 1.
Server address: e.g., xxx.pstn.twillio.com
  1. Here select Authorization type as you opted in step 2.
  • If IP type is the option you have selected, add the IPs
54.244.51.0
  54.244.51.1  
  54.244.51.2
  54.244.51.3
54.172.60.0
  54.172.60.1
  54.172.60.2
  54.172.60.3

  1. Select the country of where your SIP trunk is located.

​
Step 4: Verify Setup

After configuration:

  1. Make a test call to your number/extension
  2. Check that the AI assistant answers
  3. Use the test call feature to verify outbound calling

​
