Outbound Call Setup
An outbound call request sequence that results in call acceptance by
the remote side is illustrated in Figure 53 . The Host application
issues the module an L4L3mCALL_REQUEST message with the
following R2 payload entries:
l43msg.msgtype = L4L3mCALL_REQUEST;
l43msg.lapdid = 0x1;
l43msg.data.call_req_data.bchannel = 1;
l43msg.data.call_req_data.called_party.num_digits
l43msg.data.call_req_data.called_party.dnis_category
(set to an IISDN_R2MF_SIGNAL_CODES value)
l43msg.data.call_req_data.called_party.digits (ASCII
string)
l43msg.data.call_req_data.calling_party.num_digits
l43msg.data.call_req_data.calling_party.ani_category
(set to an IISDN_R2MF_SIGNAL_CODES value)
l43msg.data.call_req_data.calling_party.presentation_ind
(set to an IISDN_R2_ANI_XXXX value)
l43msg.data.call_req_data.calling_party.digits (ASCII
string)
l43msg.data.call_req_data.call_type (set to
IISDNcalltypR2_GND for a terrestrial circuit or
IISDNcalltypR2_SAT for a satellite circuit)
