Source notes citing this source

• If a handset displays 'Can't locate a base station', check that the base station is working and move the handset closer; the network may need an additional multicell base. in context
• If a handset displays Deregistered, the guide says to click Refresh on the base Extensions page, reconnect the handset if prompted, and escalate to the service provider if unresolved. in context
• A handset showing Searching is too far from a base or the base is inactive; wait for any base reboot, confirm the base has power and a green LED, and for lasting coverage gaps add a repeater or base. in context
• A flashing red base LED with handsets showing No SIP Reg means the base cannot communicate with the call control system. in context
• A Cisco IP DECT base station LED that stays solid red and never turns green means the base cannot get an IP address; check the Ethernet cable, switch port and DHCP server. in context
• Multicell debug logging is enabled on the base Multi Cell page by setting Multi cell debug to Both, and should be set back to Disabled after troubleshooting. in context
• All base stations in a multicell system must be on the same factory-configured RF band to communicate; compare the RF Band field on each base. in context
• When the Multi Cell page shows Searching! in the DECT property column, the bases cannot communicate; move the base closer (about -75 dBm signal recommended) or add a base in between, and check for interference. in context
• For no audio with multiple handsets on a single-base system, the guide says to verify that Use Different SIP Ports is Enabled under Network Settings. in context
• Base station PCAP logs are held in RAM and are lost if the base loses power or resets before they are downloaded. in context
• A repeater with a red LED that fails registration is not in registration mode; reset it by unplugging for 30 seconds or holding its reset button for 5 seconds. in context
