Troubleshooting
Handset shows "no access" but calls are possible
This issue could occur if the IPBS, with which the handset is currently connected, is
disconnected from power and the IP network. In such situation, the handset roams to another
IPBS of the same IP-DECT system, but the roaming to the new base station is incomplete from
the IP-DECT system point of view (because the "old" IPBS doesn't answer anymore). The new
IPBS will block the location registration for about 5 to10 minutes. So the handset will show "no
access" for this time period. However, calls will be possible on this handset even if the location
registration was not accepted by the new IPBS.
