Step-by-step integration and dialplan configuration guide for Reliance Jio SIP trunks on Issabel. Call +91 75999-67999.
Integrating a Reliance Jio SIP Trunk with a Issabel environment requires specific configuration parameters to ensure outbound call authentication, correct inbound DID routing, and clean audio delivery. Our telecom engineers at Call Soft Corporation have prepared this complete configuration guide to assist call center administrators and network engineers in Thane.
Depending on whether your Jio trunk uses IP authentication (matching your static IP gateway) or user registration (auth username and secret), you will need to add custom PEER settings and Dialplan routing rules in Issabel.
In the Issabel GUI, navigate to Connectivity -> Trunks -> Add SIP (chan_sip) Trunk and apply the following settings:
For incoming calls, make sure you configure an Inbound Route in Issabel pointing your pilot/DID numbers to your IVR or Queue.
For most Indian operators, voice traffic must be routed via a dedicated gateway interface on your server or router. Ensure that your server is configured with the correct static routes. For example:
Additionally, disable SIP ALG on your office router or firewall. SIP ALG commonly alters headers and breaks registration or causes one-way audio issues. Ensure UDP ports 5060 (SIP signaling) and UDP ports 10000–20000 (RTP media) are open and forwarded correctly.
This usually occurs if the outbound Caller ID set in your dialer/PBX does not match the active DID or pilot number authorized by Jio. Double check that the Caller ID format conforms to your telecom provider's requirements.
One-way audio is almost always caused by missing static routes on your Asterisk OS or firewall issues (NAT configuration). Make sure the media IP range of Jio is routed correctly and RTP port forwarding is enabled.
