Installing the package is quite simple.

• be sure to have asterisk installed (along with headers files)
• be sure to have kernel headers installed, to be able to compile kernel modules (kernel must be > 2.6.11 )
• in visdn src dir, just do ./configure ; make ; make install
• cp samples/30-visdn.rules to /etc/udev/rules.d (if asterisk is running as non-root, change the above file to set the right devices permissions. You can check an alternative rules file HERE )
• copy samples/vgsm.conf and vgsm_operators.conf to you asterisk conf dir, normally /etc/asterisk
• edit the vgsm.conf according to the SIMs present on the board
• load the kernel modules: modprobe visdn_vgsm; modprobe visdn_streamport; modprobe visdn_timer_system
• start asterisk :)
• with "show vgsm interfaces" you should see each interface status (Example)
• with "show vgsm interfaces _interface_name_" you should see the detailed info of the interface selected ( Example )
  *to dial out, just write into the dialplan: exten => _33.,1,Dial(VGSM/_interface_name_/${EXTEN})
