3CX Configuration Guide

Connect a 3CX phone system to Briva Voice

Ask Briva Voice support for the SIP trunk configuration appropriate to your account and 3CX version. You will need the assigned trunk number, authentication details, registrar, and routing requirements.

Before you begin

• Confirm that the SIP trunk is active.
• Have your 3CX administrator review the current 3CX network requirements and run the Firewall Checker.
• Review NAT and SIP ALG behavior with your network administrator.
• Use the provider template or configuration specifically identified by Briva Voice support for your version.

Configure and test routing

1. Add the SIP trunk using the settings provided by Briva Voice.
2. Enter the assigned authentication details and registrar.
3. Add the numbers assigned to the trunk.
4. Create inbound rules for each destination and outbound rules for the required dialing patterns.
5. Confirm number formats, outbound caller ID, emergency calling configuration, and audio in both directions.

Your 3CX administrator manages the 3CX system and its local network. Briva Voice support can help verify the trunk-side settings.
