How to Configure Tata SIP Trunk on FreePBX/Asterisk
Setting up a telecom voice trunk requires technical static routing rules and SIP trunk options configuration. Here is the step-by-step workflow:
Physical Feasibility & Link Commissioning
The telecom operator delivers a dedicated fiber cable to your server room. This is terminated into an ONT or dynamic gateway router which segregates the VoIP network.
Configure Router Static Routes
Set up a static routing policy on your main gateway firewall (e.g. Sophos, Fortinet, Mikrotik) to direct all SIP and media traffic destined for the operator softswitch IP through the dedicated gateway port.
Create SIP Trunk Peer in PBX
Inside FreePBX or Asterisk, create a new SIP/PJSIP trunk. Add the host details (Registrar/Proxy IP provided by Tata), select codecs (G711a/G729), and set authentication to "None/Static IP".
Configure Inbound and Outbound Routes
Map your DID numbers to ring groups or IVR system in Inbound Routes. Map outbound dial patterns (like dialing 9 before call) to route outbound voice calls through this new trunk.
