The following procedure describes how to configure trunks through the Web interface. You can also
configure trunks through ini file parameters or CLI (configure voip > interface).
➢
To configure a new trunk:
1. Open the Trunk Settings page (Setup menu > Signaling & Media tab > Gateway folder >
Trunks & Groups > Trunks).
The parameters displayed on the Trunk Settings page depends on the protocol type
(configured by the 'Protocol Type' parameter).
When modifying an existing |(configured) trunk through the Web interface, some
parameters require you to first stop the trunk. The Web interface displays the
values of these parameters as grayed out. To configure these parameters, stop the
trunk by clicking the Stop Trunk button, modify the parameter values, and then
click the Apply Trunk Settings (or Apply to All Trunks) button. For all other
parameters, simply modify their parameter values, and then click Submit.
To delete a configured trunk, configure the 'Protocol Type' parameter to NONE.
You cannot configure trunks that you have deactivated.
You cannot activate or deactivate a stopped trunk.
If the trunk can't be stopped because it provides the device's clock (assuming the
device is synchronized with the trunk clock), assign a different trunk to provide the
device's clock or enable 'TDM Bus PSTN Auto Clock' in the TDM Bus Settings
page (see TDM and Timing).
If you configure the 'Protocol Type' parameter to NONE (i.e., no protocol type is
selected) and no other trunks have been configured, after selecting a PRI protocol
type, you must reset the device.
BRI trunks can operate with E1 or T1 trunks.
All PRI trunks of the device must be of the same line type (either E1 or T1).
However, different variants of the same line type can be configured on different
trunks. For example, E1 Euro ISDN and E1 CAS (subject to the constraints in the
device's Release Note).
The ISDN BRI North American variants (NI-2, DMS-100, and 5ESS) are partially
supported by the device. Please contact the sales representative of your
purchased device before implementing this protocol.
If the protocol type is CAS, you can assign or modify a dial plan (in the 'Dial Plan'
field) and perform this without stopping the trunk.
When configuring through ini file, if you want to configure a parameter for a specific
trunk, append the parameter name with an underscore (_) followed by the trunk ID
(i.e., ProtocolType_x, where x denotes the trunk ID). When using this format, the
first trunk (ID 1) is denoted with a 0, trunk ID 2 with a 1, trunk ID 3 with a 2, and so
on.
