Best guess given the above... asterisk is probably detecting a tone or 
noise coming from the central office, and/or, detecting tip-ring open or 
polarity reversal during the dialing. (I'm not familiar with your 
country telco standards, so this might not be all that helpful.)
Try...
  busydetect=yes
  busycount=6
  callprogress=no
towards the top of your zapata.conf statements.

If those don't have any impact, post a piece of your zapata.conf file.
