Creating a Standalone Outgoing Call

   ptrOutgoingLegAttribute->GetCalledNumber()         = "123-4567";

Creating a Media-only Leg

If you are using the NAP_MEDIA_TDM:

   PTRCTBCMC_MEDIA_ONLY_LEG_ATTRIBUTE ptrLegAttribute;
   ptrLegAttribute = tbnew CTBCMC_MEDIA_ONLY_LEG_ATTRIBUTE();
 
   ptrLegAttribute->GetNetworkAccessPoint()      = "NAP_SS7_MONTREAL";
   
   pMediaDesc = ptrLegAttribute->GetProfile()->MediaDescription;
   pMediaDesc->Type                              = TBCMC_MEDIA_TYPE_AUDIO;
   pMediaDesc->Transport                         = TBCMC_MEDIA_TRANSPORT_TDM;
   pMediaDesc->Settings.TdmAudio.Type            = TBCMC_MEDIA_SETTINGS_TYPE_TDM_AUDIO;
   pMediaDesc->Settings.TdmAudio.un8Timeslot     = 5;
   Strncpy
   (
       pMediaDesc->Settings.TdmAudio.szTrunkName, 
       "TRUNK_TORONTO_1", 
       sizeof(pMediaDesc->Settings.TdmAudio.szTrunkName)
   );
 
   PCTBCMCLeg pCallLeg = tbnew CTBCMCLeg( ++mun32LegId, ptrLegAttribute, this, 0, &mLegMutex );
   pCallLeg->CreateCall();

If you are using the NAP_MEDIA_VOIP:

   TBX_RESULT                         Result;
   TBX_SDP_INFO                       SdpInfo;
   PTRCTBCMC_MEDIA_ONLY_LEG_ATTRIBUTE ptrLegAttribute;
   ptrLegAttribute = tbnew CTBCMC_MEDIA_ONLY_LEG_ATTRIBUTE();
 
   ptrLegAttribute->GetNetworkAccessPoint()      = "NAP_SS7_MONTREAL";
   
   pMediaDesc = ptrLegAttribute->GetProfile()->MediaDescription;
   pMediaDesc->Type                              = TBCMC_MEDIA_TYPE_AUDIO;
   pMediaDesc->Transport                         = TBCMC_MEDIA_TRANSPORT_IP;
   pMediaDesc->Settings.PacketAudio.Type         = TBCMC_MEDIA_SETTINGS_TYPE_PACKET_AUDIO;
  
   // Set Local SDP
   Result = BuildSdpInfo("", 0, SdpInfo);                 // No IP specified, Toolpack will choose one
   TBCAF_EXIT_ON_ERROR( Result, "BuildSdpInfo failed." );
   ptrLegAttribute->SetLocalSDP(&SdpInfo);
   
   // Set Peer SDP
   Result = BuildSdpInfo("10.0.0.15", 5000, SdpInfo);     // Using peer IP address and port
   TBCAF_EXIT_ON_ERROR( Result, "BuildSdpInfo failed." );
   ptrLegAttribute->SetPeerSDP(&SdpInfo);
 
   PCTBCMCLeg pCallLeg = tbnew CTBCMCLeg( ++mun32LegId, ptrLegAttribute, this, 0, &mLegMutex );
   pCallLeg->CreateCall();
