Hi José,

your assumption looks correct according to the Gobi API:

// Structure to describe indication TLV 0x14 for Voice AllCallStatusIndication
struct sVoiceAllCallStatusIndication_CallEndReason
{
   UINT8 mCallInstanceCount;

   struct sInstance
   {
      UINT8 mCallID;
      eQMIVoiceEndReasons mEndReason;
   };

   // This array must be the size specified by mCallInstanceCount
   // sInstance mInstances[1];
};

You can find snapshots of various Gobi API releases before
https://bye.codeaurora.org/ in the libqmi git repo and an archived copy
of the changes after the last CodeAurora release in 2013 as part of
https://git.codelinaro.org/clo/qsdk/oss/lklm/gobinet .

It might make sense to check
https://git.codelinaro.org/clo/le/platform/vendor/qcom-opensource/snaptel-sdk
for a type which corresponds to eQMIVoiceEndReasons (enum class FailureCause
in SuppServicesManager.hpp perhaps) and add the additional values to the
libqmi eqivalent of eQMIVoiceEndReasons.
