Physical Connectivity of SIP PRI Gateway

Proper physical connections are essential for smooth operation. Follow these steps:

1. Power Connection – Connect the gateway to a power source and turn it on.
2. Network Connectivity – Use an Ethernet cable to connect the gateway to your local network (LAN).
3. PRI Line Connection – Plug the PRI cables into the E1/T1 ports of the gateway.
4. PBX Connection – Connect the gateway to your IP-PBX or traditional PBX system.
5. SIP Trunk Connection – Configure the gateway to connect with your SIP service provider over the internet.

Steps to Configure SIP PRI Gateway

Once the hardware is set up, follow these steps to configure the gateway:

Step 1: Access the Web Interface
