Adding a Third-Party SIP Provider to UniFi Talk

If you currently subscribe to a third-party SIP provider, you can use your existing service with your UniFi Talk deployment without needing to purchase an official UniFi Talk subscription. Third-party SIP configuration is possible only with unlocked UniFi Talk phones. This guide will walk you through configuring SIP Trunk and connecting your provider to UniFi Talk.

To simplify the setup process, we have prepared templates for the following SIP providers: Breeze Connect, Deutsche Telekom, easybell, DIDWW, Telnyx, and VoIP.ms. While you can configure UniFi Talk with any SIP provider for maximum flexibility, please note that our support team will not be able to assist with SIP providers that are not listed.

Create & Configure SIP Trunking

Set Up a New SIP Trunk

Before configuring UniFi Talk, set up a new SIP trunk through your SIP provider's dashboard. Note that these instructions are general; consult your provider's documentation for specific details.

1. Create a new SIP trunk:
   • Set the authentication credentials (username and password).
2. Add your router's public IP address to the IP Access Control List (ACL):
   • If required, add a new entry for your router's public IP address. Depending on your provider’s requirements, you may need to enter this IP address, use CIDR notation, or include a port number (e.g., 1.2.3.4:6767).
   • We recommend specifying port 6767, as it is used by UniFi Talk when the Static Signaling Port setting is enabled.
3. Assign Direct Inward Dialing (DID) numbers:
   • Ensure that the DID numbers you want to use with UniFi Talk are assigned to the newly created SIP trunk.

Configure UniFi Talk

1. Enable Static Signaling Port:
   • Navigate to System Settings in UniFi Talk and enable the Static Signaling Port to use port 6767 for SIP signaling.
2. Select Add Third-Party SIP Provider and fill out the necessary fields:
   • Custom Fields: Reference your provider’s ITSPs directory or user documentation.
   • Destination Countries: Select specific countries for routing through this SIP provider.
   • Handle All Outgoing Calls By Default: Enable if you want all outgoing calls routed through this SIP provider.
   • DID Numbers & IP Address Range: Enter the IP addresses of the servers used by your SIP provider.

Assign DID Numbers

Once your SIP provider is connected and your DID numbers are imported, assign them to your users. For more information, refer to our Managing Users guide.

Note: If you're using a third-party SIP provider, they will be responsible for maintaining E911 compliance. Contact your provider for guidance on meeting these requirements.

Adjust Port Forwarding Rules

Some third-party SIP configurations require the Static Signaling Port setting to be enabled. Follow these steps to adjust port forwarding rules:

1. Enable Static Signaling Port:
   • In the Talk application, go to Settings > System Settings > Static Signaling Port and check the box.
2. Create Port Forwarding Rule:
   • If your routing tasks are handled by UniFi, go to Network application > Settings > Security > Port Forwarding and create a rule:
     • Interface: Both
     • From: Any
     • Port: 6767
     • Forward IP: Your UniFi Console’s IP address (e.g., 192.168.1.1)
     • Forward Port: 6767
     • Protocol: Both
3. Forward Port 6767 from Upstream Routers:
   • If you have another router upstream, forward incoming traffic on port 6767 from that router to your UniFi Console.
4. Create Firewall Rule:
   • If your firewall rules are managed by UniFi, go to Network application > Settings > Security > Traffic & Firewall Rules and create a rule:
     • Rule Type: Advanced
     • Type: Internet Local
     • Action: Accept
     • Protocol: All
     • Source Type: Port/IP Group
     • Address Group: Any
     • Port Group: Any
     • Destination Type: Port/IP Group
     • Address Group: Any
     • Port Group: Select New
     • Profile Name: Enter a name
     • Port: 6767, select Add
     • Create
