Trunks

Trunks are configuration elements that define how ipbx communicates with outside phone systems. Multi Site trunking does not require additional trunk configuration and communication/authentication is completely automated via master settings.

VoIP Trunks

VoIP Trunks can either be SIP or IAX2 based. While trunks are very similar to channels, their configuration is supposed to be static and take care of interconnection between systems.

Trunks List

To view the trunks list, click on Configuration → VoIP Trunks.

This interaction displays all your configured VoIP trunks. Click on the icon to edit a trunk, or click on the icon to remove the trunk. Click on ping to find out whether the host is alive or not. An appropriate signaling packet will be sent and response will be expected. Note that a successful reply is no guarantee for correct trunk configuration.

Add Trunk

To add a trunk, click on Configuration → VoIP Trunks and click on add SIP trunk or add IAX trunk.

Trunks are usually static (static IP address). For detailed explanation of trunk parameter see adding SIP channels or adding IAX channels.

Registrations List

To view your registrations click on Configuration → VoIP Trunks → Registrations.

The registration list shows you with which other servers your ipbx is registered to. This behavior is akin to a phone/client registered to ipbx.

This interaction will display your registration settings and show whether your system is properly registered with the remote host:

• OK, registered
• FAIL Not registered / registration lost

Click on the icon to edit a registration, or click on the icon to remove the registration.

Add Registration

To add a trunk, click on Configuration → VoIP Trunks → Registrations and click on add SIP registration or add IAX registration.

Adding SIP Registration

Registration User

The registration user as setup on the remote host. Required.

Registration Password

Authentication User

If set, an authentication user different from the the user. (optional)

Host

The remote host that will accept the registration. Required.

Extension

The mapped extension for any incoming calls. This extension will usually be looked up via Inbound Routing. The default dialplan context is incoming.

Adding IAX Registration

Registration User

The registration user as setup on the remote host. Required.

Registration Password

The registration password as setup on the remote host. (optional)

Host

The remote host that will accept the registration. Required.

PSTN / TDM Trunks

Interconnection of your ipbx system with the public switched telephone network PSTN or other TDM based systems can be either achieved using a gateway or a local TDM card.

Taridium supplied systems are usually equipped with Sangoma echo-cancelling T1/E1 PRI cards that can range from 1 to 8 ports. Check Diagnostics → Status → TDM Interfaces to see your installed cards.
