[Asterisk-Dev] Call progress events not received in Zap channels

[Daniel Montejo Biosca (hotmail)]

  Hello,
  When i make a outbound call from SIP channel to external number using
Asterisk Manager Api I receive that event:
  "Event: Newstate
  Privilege: call,all
  Channel: SIP/1003-5a38
  State: Busy
  CallerID: 1003
  CallerIDName: 1003XLiteDMB
  Uniqueid: 1129047291.38"

  But when i make a outbound call from Zap channel to external number using
Asterisk Manager Api i don't receive it.
  Why? Is possible receive it?

  Thank you
