Case for the 603 DECLINE and 200 TOOLPACK NORMAL

The TOOLPACK_NORMAL reason code is mapped to the 603_DECLINE reason code. The reason is the following:

A SIP BYE does not include a cause code, so on normal call terminations, So TMedia will send a BYE on SIP, and internally, a 200 TOOLPACK_NORMAL (in the logs and the CDRs). But when the call terminates unexpectedly, for example after a ACM, but before a ANM, Tmedia will still send a BYE on SIP, but internally, it will log a 603 Decline (REASON_CODE_603_DECLINE).
