After fixing the modprobe problem with the B200 I have problem dialling!
I am setting signalling to [font=Helvetica, Geneva, Arial, SunSans-Regular, sans-serif, Verdana,]bri_cpe_ptmp but it keeps saying "all circuits are busy now" and sometimes it dials (rings to the other end) and then it says the number is not answering, although it keeps ringing.[/font]
Afte numerous testings and with the help of Hua Upper, the conclusion is that the integrated dahdi module with freepbx 2.10 causes the problem. When I uninstalled it everything started to work fine again!
