Network Requirements

Note: Network requirements are primarily needed for private network setups. If you're using a public cloud SIP provider (e.g., Twilio, Telnyx), you typically don't need to configure these manually as they handle network routing automatically.

Before configuring inbound and outbound calls in private network environments, you need to set up network allowlists.

IP Allowlist

For private network setups, you need to allow the following IP addresses in your firewall or allowlist settings for both inbound and outbound calls:

34.139.65.119
34.75.46.115
34.138.200.23

1. Navigate to your firewall or security settings.

2. Add all three IP addresses listed above to your allowlist.

3. Save your configuration.

Port Configuration

For private network setups, you also need to configure the following ports:

For Ingress (Inbound Calls):

• SIP: Port 5060 (UDP)

• RTP: Configure RTP ports as required by your SIP provider

For Egress (Outbound Calls):

• SIP: Port 5060 (UDP)

• RTP: Ports 10000-20000 (UDP)

Note: The IP allowlist and port configuration are required for both inbound and outbound calls to work properly in private network environments.
