another problem ... when CGB for CIC 1 with range 30 is received CIC 17 remains non blocked and when a call is attemted it pickups CIC 17 ... then it gets a BLO (for 17) and when received its is properly put in blocking state. The same behavior is on CGB for 17 with range 14 - CIC 17 remains available. On CGB for 1 with range 14 it properly sets 1 to 15 as blocked. When local blocking is requested from cli the status is properly displayed. in chan_dahdi.conf: cicbeginswith=1 channel => 1-15 cicbeginswith=17 channel => 17-31 sigchan=16
