It sounds like the Ericsson pbx uses overlap dialing. Try enabling that on 
both links in the zapata.conf file and see if it works better.

For immediate=no you should not match the s context. I think 
  exten => _.,1,Dial(Zap/g2/${EXTEN})
is more correct. Or use "_XXX" for a three digit DID.

Again, the Ericson device should use overlap dialing. All that is needed 
in the pri-ericsson context is
   exten => _X.,1,Dial(Zap/g1/${EXTEN})
