I have downloaded Linux QMI SDK 04.00.26 and in section 9.39.2.8 of the PDF (Call Manager defined call end reasons (Type=3)) there is no explanation for 2007. From 2006 then 2500:
2006 - REDIR OR HANDOFF, this error code is returned when data call is brought down because device is
in the process of redirecting/handing off to a different target system
• 2500 - OFFLINE, this error code is returned when data call is brought down because traffic channel got
rejected/released by CM(Call Manager) since device went offline
What is meaning for 2007? SLQSStartDataSession fails with “CM reason 2007”
EM7565 and SWI9X50C_01.11.00.00
