Zycoo IPPBX is built on the Asterisk platform and supports the standard SIP protocol. It can connect to IMS SIP trunks from ITSPs (Internet Telephony Service Providers) as well as SIP endpoints.
This document provides instructions for E1 configuration on the T600 model.
Ensure the E1 line conforms to the standard specification.
For loopback testing, use the following pin connections:
| Connection | Pin Mapping |
|---|---|
| Line Order | 1, 2, 4, 5 |
| Connection | 1 → 4 |
| Connection | 2 → 5 |
Log in to the IPPBX web interface using the admin account.
Navigate to Telephony → Preferences → Module Settings
Important Note: If only one E1 module is being installed, please insert it into Slot 2.
| Parameter | Setting |
|---|---|
| Module Type | E1/T1 |
| Mode | E1 |
| Overlap Dial | Yes |
| Signaling | CPE |
| Framing | CCS |
| Coding | HDB3 |
| CRC4 | Disable |
After completing the configuration, click Submit. The device will require a reboot for the changes to take effect.
Navigate to Telephony → Outbound Control → Trunks
The default trunk settings are generally sufficient for most deployments.
Navigate to Telephony → Outbound Control → Dial Rules
Edit the default Dial Rule
| Parameter | Setting |
|---|---|
| DialPattern | X. |
| Available Trunks | Tick PRI-1 |
Ensure that DialPlan1 includes the DialOut rule.
Most E1 lines require caller ID authentication. Please configure the outbound caller ID as follows:
| Parameter | Setting |
|---|---|
| Outbound CID | Your line number |
Navigate to Telephony → Inbound Control → Inbound Routes
Set up the destination for the E1 trunk
Navigate to Telephony → Inbound Control → Direct Routing
Add a new DID entry and enter your line number
Important Note: If the DID is not correctly configured in Direct Routing, incoming calls will be routed to the PRI-1 trunk via the default Inbound Routes settings.
Navigate to Dashboard → Trunks
Verify that the Channel Status of the Digital Channel shows Up
If the status shows Alarm, please follow these steps:
Connect a loop cable to the E1 interface
Reboot the device
After the device has fully started up, confirm the E1 status again in the Digital Channel section
If the Digital Channel status shows Up, the E1 card is functioning properly.
