Certified integration of Reliance Communications SIP trunks with Asterisk, FreePBX, and ViciDial. Call +91 75999-67999.
Are you planning to configure or troubleshoot a Reliance Communications SIP Trunk? Call Soft Corporation provides expert telecom integration services across India. We specialize in setting up and configuring Reliance business voice services with Asterisk, FreePBX, ViciDial, Issabel, and Grandstream UCM IP PBX systems.
Telecom carriers in India like Reliance deliver SIP trunks over dedicated physical fiber Leased Lines (ILL), MPLS, or FTTX connections. Proper configuration requires precise settings for WAN interfaces, IP-based or registration-based authentication, custom static routing, and dialing rules. Our certified engineers ensure 100% reliable connectivity with zero call drops, high call quality (G.711 alaw), and proper DID mapping for your business in Kota.
Here are the standard configuration parameters required for setting up Reliance SIP trunks on Asterisk-based PBX servers:
| Parameter | Value / Details |
|---|---|
| Authentication Type | IP-Based Authentication |
| SIP Proxy Host | Provided by Reliance (specific private IP) |
| Signaling Port | 5060 (UDP) |
| DTMF Mode | RFC2833 |
| Codecs Supported | G.711 alaw, G.711 ulaw, G.729 |
| Maximum Channels | Scalable from 30 up to 1000+ concurrent calls |
1. Physical/VLAN WAN Setup: Reliance communications SIP trunks (enterprise business voice) are configured using IP-based authentication over dedicated network connections. They support multiple concurrent channels for outbound dialers and high-volume inbound call centers. Configuration requires establishing proper gateway settings, signaling IPs, and mapping the DID blocks correctly within your Asterisk or Grandstream UCM environment.
2. Define OS Level Static Routes: You must route the SIP signaling IP and RTP voice IP ranges through the telecom gateway gateway IP rather than your public internet link. On Linux, run:
3. Outbound Dialplan: In FreePBX or ViciDial, define the dialing prefix and outbound Caller ID to match your allocated pilot number exactly. Contact our team at +91 75999-67999 for custom scripting or troubleshooting help.
Reliance SIP trunks offer superior scalability (you can add channels without adding hardware), redundancy, lower call charges, and direct digital IP-to-IP connectivity.
If your PBX is purely IP-based (like Asterisk/FreePBX), you do not need a physical gateway. However, if you are using an older analog/digital PBX, you will need a VoIP gateway (like Dinstar or Grandstream) to convert SIP to PRI/FXO.
