# Manage phone.systems(TM) trunks

Manage existing inbound phone.systems(TM) trunks from the **Inbound Trunks**
page. View a trunk's configuration, edit its settings, enable CNAM lookup, or
delete trunks that are no longer required.

These settings control caller ID and caller name delivery to your
phone.systems(TM) PBX. To change how the PBX answers and routes calls,
[launch and configure phone.systems(TM)](../../../../phone-systems/Getting-started/index.html#ps3-launch-and-configure).

## Before you begin

  one, see [Create a phone.systems(TM) trunk](create-phone-systems-trunk.html).
