CAF: Leg Creation Samples

Creating a Standalone Outgoing Call

First you must build the outgoing leg attribute:

   PTRCTBCMC_CALL_LEG_ATTRIBUTE ptrOutgoingLegAttribute;
 
   ptrOutgoingLegAttribute = tbnew CTBCMC_CALL_LEG_ATTRIBUTE();
 
   ptrOutgoingLegAttribute->GetCalledNumber()            = "123-4567";
   ptrOutgoingLegAttribute->GetCallingNumber()           = "987-6543";
   ptrOutgoingLegAttribute->GetNetworkAccessPoint()      = "NAP_SS7_MONTREAL";

Once you have all your parameters set, you can now create the outgoing call leg like this:

   PTRCTBCAFCallLeg ptrOutgoingCallLeg = CreateOutgoingCallLeg(ptrOutgoingLegAttribute);

The function CreateOutgoingCallLeg() will do all the work to create the leg and will return it. You have now an active outgoing call leg.

Creating a Media-only Leg

You must first create a media only leg attribute:

   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 or TBCMC_MEDIA_TRANSPORT_IP;

Depending on which type of NAP your using, some parameters must be set. If you are using the NAP_MEDIA_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)
   );

If you are using the NAP_MEDIA_VOIP:

   TBX_RESULT               Result;
   TBX_SDP_INFO             SdpInfo;
   
   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);
