Passthrough

Allows route calls received from a trunk straight to another trunk.

Configuration

Trunk configuration

Note

If you are using a SIP trunk as an origin trunk, skip this step and go to ‘Route Configuration’.

First login as ‘localadmin’, click on ‘Local’ and then on ‘Brick type’ menu.

If you already have configured the trunks, click on ‘Edit’ button beside the trunk that you want to configure the passthrough. On the ‘Add trunk’ window, look for the ‘Channelstring’ field.

If you’re creating the trunk now, click on ‘Add trunk’ button. Then select type ‘Custom’ and the field ‘Channelstring’ will appear.

The ‘Channelstring’ field identify the channels of one trunk, used to permit or deny the passthrough from this trunk.

For example, if you’re using a khomp board, usually the channel string will be ‘b0l1’. This string identify the board 0 and link 1.

Route configuration

After that, you have to configure the routes allowing route calls from this entity. To do it, login as ‘admin’ and edit the chosen route adding on ‘Access control’ this trunk(Passthrough Trunks).
