CALL COMPLETION FOR TRUNKS
CONFIGURATION
Call completion for trunks is only applicable to SIP register trunks. Two UCM6100s must be first configured
with SIP trunks registered to each other. For the sake of the following illustration, we name the two
UCM6100s involved in this example UCM1 with IP address 192.168.40.233 and UCM2 with IP address
192.168.40.216 respectively.
1. On UCM1, create extension 1000. This extension is for UCM2 to register SIP trunk to UCM1.
2. On UCM1 extension 1000, go to “Features” tab and make sure the following are configured:
 “Enable CC”: selected
 “CC Mode”: set to “For Trunk”
