  I see a curious startup with the new stack of Dect
protocol. I have one
 laptop (Debian+Dect DOSCH-AMAND  pcmcia radio U2785B) and a computer
 with DOSCH-AMAND  PCI with the same kernel and compilation

 I do all instructions of http://dect.osmocom.org/README. When finish all
 configurations and start the daemon Asterix in debug mode i can see the
 next event on the log:

 1) Start the daemon:

 # /etc/init.d/asterisk debug

  == Registered channel type 'DECT' (Digital Enhanced Cordless
 Telecommunications (DECT))
   == Parsing '/etc/asterisk/dect.conf':   == Found
     -- Registered extension context 'dect_register' (0xc548c10) in table
 0xc5b21c0; registrar: DECT
     -- Added extension '601' priority 1 to dect_register (0xc548c10)
     -- Added extension '602' priority 1 to dect_register (0xc548c10)
     -- Added extension '603' priority 1 to dect_register (0xc548c10)
 *dect_netlink_init: Object not found* 
This indicates the cluster doesn't exist.

...
  *[Sep 28 00:31:22] ERROR[20318]: chan_dect.c:1905
dect_load_module:
 Unable to initialize DECT handle*

 2)Here's what I think that first create the cluster, and proceed to
 activate FP mode to realize the call server:

 #dect-cluster-add --name cluster0 --emc 0x1182 --fpn 0x0fac2 --mode fp
 #dect-cell-add --name cell0 --cluster cluster0
 #dect-transceiver-bind --transceiver trx0 --cell cell0

 3) Launch another time Asterix in Debug, and failed too:

 # /etc/init.d/asterisk debug

   == Registered channel type 'DECT' (Digital Enhanced Cordless
 Telecommunications (DECT))
   == Parsing '/etc/asterisk/dect.conf':   == Found
     -- Registered extension context 'dect_register' (0xbfc4d50) in table
 0xbebd608; registrar: DECT
     -- Added extension '601' priority 1 to dect_register (0xbfc4d50)
     -- Added extension '602' priority 1 to dect_register (0xbfc4d50)
     -- Added extension '603' priority 1 to dect_register (0xbfc4d50)
 *LCE: dect_lce_init: Permission denied* 
Asterisk is dropping permissions at startup, so you're unable to
bind to the cluster. Try starting it as root using "asterisk -pfc".
I'll look into fixing this, AFAIK asterisk retains the CAP_NET_ADMIN
capability, so I'll probably adjust the permission checks to accept
that.

  *[Sep 28 00:33:56] ERROR[20438]: chan_dect.c:1905
dect_load_module:
 Unable to initialize DECT handle*

 4) The posible Workaround (I think that all my config is correct) to get
 up  the daemon Asterix is do this order:

 *delete the cluster:*

 #dect-cluster-delete --name cluster0
 #dect-cell-delete --cell cell0

 *Detected broadcast message for all:*

  5)Then start daemon on debug
 *#/etc/init.d/asterisk debug*

  func_blacklist.so => (Look up Caller*ID name/number from blacklist
 database)
   == Registered channel type 'DECT' (Digital Enhanced Cordless
 Telecommunications (DECT))
   == Parsing '/etc/asterisk/dect.conf':   == Found
     -- Registered extension context 'dect_register' (0xd3bcd50) in table
 0xd2b5608; registrar: DECT
     -- Added extension '601' priority 1 to dect_register (0xd3bcd50)
     -- Added extension '602' priority 1 to dect_register (0xd3bcd50)
     -- Added extension '603' priority 1 to dect_register (0xd3bcd50)

 And then the Daemon start "apparently" correct

 Some questions:

 1) its posible that need create the cluster,cell and Rtx before launch
 Asterix ? 
Yes, that's how its supposed to work.

...
  2)Its posible that need create all the componets of
the cluster with and
 only with user as asterisk?

 3) When i run  "*nl-link-list" *i can see all interfaces , but i cant
 see "a dect interface" , its is normal ? 

 # ./nl-link-list
 lo loopback <loopback,up,running,lowerup>
 eth0 ether 00:06:1b:de:ee:4c <broadcast,multicast>
 eth1 ether 00:0c:f1:28:60:f4 <broadcast,multicast,up,running,lowerup>
 pan0 ether 6a:08:e2:74:24:db <broadcast,multicast> 
There is dect-cluster-list, dect-cell-list and dect-transceiver-list
for listing the respective DECT components.
