Set Up Inbound Routing

The default inbound route destination in the UC300/UC500 is a ring group that includes the 10 preset SIP extensions. To edit inbound routing or add a new route, navigate to PBX > Call Control > Inbound Routes. Here you can define how to route incoming calls to your system on any trunk, including defining expected DID&CID numbers, inbound destinations, and so on.
