Outgoing Call Processing
During an outgoing call, the host receives an L3L4mPROGRESS in 
response to the L4L3mCALL_REQUEST to start the call. The host 
then receives an L3L4mSEIZE_COMP message if send_seize_comp_
event = 1 in the IISDN_ROBBED_BIT_DATA structure. This 
message is sent when the module detects a wink from the network, 
indicating the network is ready to receive digits. After the digits are 
transmitted, the module waits for answer supervision from the 
network (indicating the far end has gone off hook) or for an answer 
timer to expire (if timed_answer_supervision = 1). When answer 
supervision is received or the timer expires, the host receives an 
L3L4mCONNECT indicating the call is connected.
 shows how the module makes an outgoing call over a wink 
start or delay dial trunk.
