1. Create SIP trunk in 3CX
- 3CX Management Console → SIP Trunks → Add SIP Trunk → Generic SIP Trunk.
- Registrar / Host:
— - Authentication ID:
— - Password: use the password shown above (unique to your property).
- Enable Register so 3CX registers to TataVoice.
- Codec priority:
PCMU,PCMA,OPUS.
2. Route inbound calls
- Create an inbound rule or DID route that forwards calls to this SIP trunk.
- For testing, create an extension that routes to the trunk after hours or on overflow.
- Calls hitting your trunk username
—are answered by your AI agent.
3. Firewall & NAT
Allow UDP/TCP 5060 and RTP between your 3CX server and —.
If 3CX is behind NAT, set the correct external IP and enable RTP port range forwarding.
4. Test your line
Place a test call to your DID. You should hear your configured greeting from the dashboard voice settings. Check Recent calls for duration and transcript.
Security: Do not share these credentials. Each TataVoice customer has a separate SIP username — calls are billed to your wallet only when your trunk is used.
