Hi ,

I am still facing the same error
"Unable to load module chan_ss7.so
Command 'module load chan_ss7.so' failed.
[Aug 16 09:37:16] WARNING[30128]: loader.c:446 load_dynamic_module: Error
loading module 'chan_ss7.so': /usr/lib/asterisk/modules/chan_ss7.so:
undefined symbol: cmd_unblock"


Sorry, chan_ss7.so was in the same path you explained
(/usr/lib/asterisk/modules) I checked.
And I am using the following version of dahdi-linux, dahdi tool and chan_ss7

Dahdi-linux/tools:DAHDI: 2.0.x
chan_ss7:chan_ss7-1.4.3

I got them installed from

`svn co http://svn.digium.com/svn/dahdi/linux/trunk dahdi-trunk`
`cd dahdi-trunk`
`make; make install`

`svn co http://svn.digium.com/svn/dahdi/tools/trunk dahdi-tools`
`cd dahdi-tools`
`./configure; make; make install`

As I am novice in this field i have some query if possible please answer :

1.) Is this error coming due to "NO E1 Card installed"? As i did not plug
any E1 card till now
2.)Bringing Dahdi up is giving the following error

./dahdi.init start
Loading DAHDI hardware modules:
  wct4xxp:                                                 [  OK  ]

  xpp_usb:                                                 [  OK  ]

No hardware timing source found in /proc/dahdi, loading dahdi_dummy
Running dahdi_cfg:  DAHDI_SPANCONFIG failed on span 1: No such device or
address (6)
                                                           [FAILED]
Is this error  also due to no E1 Card in the PCI slot.

Please send me any document covering complete step.

Thanks
Nitesh
