Hi,
I found a solution for making an outbound call and having control
over read and write frames in a while loop.
First step is make outbound call without Caller Session:
switch_ivr_originate(NULL,peerSession,cause,"user/1010 at 192.168"....);
Second step is transfer peerSession to an extension in Dialplan doing
the while-loop (read and write frames):
switch_core_session_execute_exten(peerSession,"Test","XML","default");
regards
