wg1r1#csim start 089150
csim: called number = 089150, loop count = 1 ping count = 0
csim err csimDisconnected recvd DISC cid(21)
csim: loop = 1, failed = 1
csim: call attempted = 1, setup failed = 1, tone failed = 0

wg1r1#csim start 089151
csim: called number = 089151, loop count = 1 ping count = 0
